    options.










[-autoclear autoClear] A
    boolean value which specifies whether the first keypress in a cell will
    delete whatever text was previously there. Defaults to 0.
    [-bordercursor borderCursor] Specifies
    the name of the cursor to show when over borders, a visual indication that
    interactive resizing is allowed (it is thus affect by the value of
    -resizeborders). Defaults to crosshair.
    [-borderwidth or -bd borderWidth]
    Specifies a non-negative pixel value or list of values indicating the width
    of the 3-D border to draw on interior table cells (if such a border is being
    drawn; the relief option typically determines this). If one value is
    specified, a rectangle of this width will be drawn. If two values are
    specified, then only the left and right edges of the cell will have borders.
    If four values are specified, then the values correspond to the {left right
    top bottom} edges. This can be overridden by the a tag's borderwidth option.
    It can also be affected by the defined -drawmode for the table. Each
    value in the list must have one of the forms acceptable to
    Tk_GetPixels. [-browsecommand or -browsecmd
    browseCommand] Specifies a command which will be evaluated
    anytime the active cell changes. It uses the %-substition model described in
    COMMAND SUBSTITUTION below. Any changes to the active cell while the command
    is running are ignored to prevent recursion. [-cache
    cache] A boolean value that specifies whether an internal
    cache of the table contents should be kept. This greatly enhances speed
    performance when used with -command but uses extra memory. Can
    maintain state when both -command and -variable are empty. The
    cache is automatically flushed whenever the value of -cache or
    -variable changes, otherwise you have to explicitly call clear
    on it. Defaults to off. [-colorigin
    colOrigin] Specifies what column index to interpret as the
    leftmost column in the table. This value is used for user indices in the
    table. Defaults to 0. [-cols cols]
    Number of cols in the table. Defaults to 10.
    [-colseparator colSeparator] Specifies
    a separator character that will be interpreted as the column separator when
    cutting or pasting data in a table. By default, columns are separated as
    elements of a tcl list. [-colstretchmode
    colStretchMode] Specifies one of the following stretch modes
    for columns to fill extra allocated window space:





  

  
Columns will not stretch to fill the assigned window space. If the columns
      are too narrow, there will be a blank space at the right of the table.
      This is the default.

  

  
Only columns that do not have a specific width set will be stretched.

  

  
All columns will be stretched by the same number of pixels to fill the
      window space allocated to the table. This mode can interfere with
      interactive border resizing which tries to force column width.

  

  
The last column will be stretched to fill the window space allocated to
      the table.

  

  
The table will get more or less columns according to the window space
      allocated to the table. This mode has numerous quirks and may disappear in
      the future.





[-coltagcommand colTagCommand] Provides
  the name of a procedure that will be evaluated by the widget to determine the
  tag to be used for a given column. When displaying a cell, the table widget
  will first check to see if a tag has been defined using the tag col
  widget method. If no tag is found, it will evaluate the named procedure
  passing the column number in question as the sole argument. The procedure is
  expected to return the name of a tag to use, or a null string. Errors
  occurring during the evaluation of the procedure, or the return of an invalid
  tag name are silently ignored. [-colwidth
  colWidth] Default column width, interpreted as characters in the
  default font when the number is positive, or pixels if it is negative.
  Defaults to 10. [-command command]
  Specified a command to use as a procedural interface to cell values. If
  -usecommand is true, this command will be used instead of any reference
  to the -variable array. When retrieving cell values, the return value
  of the command is used as the value for the cell. It uses the %-substition
  model described in COMMAND SUBSTITUTION below.
  [-drawmode drawMode] Sets the table
  drawing mode to one of the following options:




  

  
The table is drawn to an offscreen pixmap using the Tk bordering functions
      (double-buffering). This means there will be no flashing, but this mode is
      slow for larger tables.

  

  
The table is drawn directly to the screen using the Tk border functions.
      It is faster, but the screen may flash on update. This is the
    default.

  

  
The table is drawn directly to the screen and the borders are done with
      fast X calls, so they are always one pixel wide only. As a side effect, it
      restricts -borderwidth to a range of 0 or 1. This mode provides
      best performance for large tables, but can flash on redraw and is not 100%
      Tk compatible on the border mode.

  

  
The table is drawn to the screen as in fast mode, but only single pixel
      lines are drawn (not square borders).





[-ellipsis ellipsis] This specifies a
  string to display at the end of a line that would be clipped by its cell, like
  ``...''. An ellipsis will be displayed only on non-wrapping, non-multiline
  cells that would be clipped. The ellipsis will display on the left for east
  anchored cells, otherwise it displays on the right. Defaults to ""
  (no ellipsis). [-flashmode flashMode] A
  boolean value which specifies whether cells should flash when their value
  changes. The table tag flash will be applied to these cells for the
  duration specified by -flashtime. Defaults to 0.
  [-flashtime flashTime] The amount of
  time, in 1/4 second increments, for which a cell should flash when its value
  has changed. -flashmode must be on. Defaults to 2.
  [-height height] Specifies the desired
  height for the window, in rows. If zero or less, then the desired height for
  the window is made just large enough to hold all the rows in the table. The
  height can be further limited by -maxheight.
  [-invertselected invertSelected]
  Specifies whether the foreground and background of an item should simply have
  their values swapped instead of merging the sel tag options when the
  cell is selected. Defaults to 0 (merge sel tag).
  [-ipadx ipadX] A pixel value specifying
  the internal offset X padding for text in a cell. This value does not grow the
  size of the cell, it just causes the text to be drawn further from the cell
  border. It only affects one side (depending on anchor). Defaults to 0. See
  -padx for an alternate padding style. [-ipady
  ipadY] A pixel value specifying the internal offset Y padding
  for text in a cell. This value does not grow the size of the cell, it just
  causes the text to be drawn further from the cell border. It only affects one
  side (depending on anchor). Defaults to 0. See -pady for an alternate
  padding style. [-justify justify] How to
  justify multi-line text in a cell. It must be one of left,
  right, or center. Defaults to left.
  [-maxheight maxHeight] The max height in
  pixels that the window will request. Defaults to 600.
  [-maxwidth maxWidth] The max width in
  pixels that the window will request. Defaults to 800.
  [-multiline multiline] Specifies the
  default setting for the multiline tag option. Defaults to 1.
  [-padx padX] A pixel value specifying
  the offset X padding for a cell. This value causes the default size of the
  cell to increase by two times the value (one for each side), unless a specific
  pixel size is chosen for the cell with the width command. This will
  force an empty area on the left and right of each cell edge. This padding
  affects all types of data in the cell. Defaults to 0. See -ipadx for an
  alternate padding style. [-pady padY] A
  pixel value specifying the offset Y padding for a cell. This value causes the
  default size of the cell to increase by two times the value (one for each
  side), unless a specific pixel size is chosen for the cell with the
  height command. This will force an empty area on the top and bottom of
  each cell edge. This padding affects all types of data in the cell. Defaults
  to 0. See -ipadx for an alternate padding style.
  [-resizeborders resizeBorders] Specifies
  what kind of interactive border resizing to allow, must be one of row, col,
  both (default) or none. [-rowheight
  rowHeight] Default row height, interpreted as lines in the
  default font when the number is positive, or pixels if it is negative.
  Defaults to 1. [-roworigin rowOrigin]
  Specifies what row index to interpret as the topmost row in the table. This
  value is used for user indices in the table. Defaults to 0.
  [-rows rows] Number of rows in the
  table. Defaults to 10. [-rowseparator
  rowSeparator] Specifies a separator character that will be
  interpreted as the row separator when cutting or pasting data in a table. By
  default, rows are separated as tcl lists.
  [-rowstretchmode rowStretchMode]
  Specifies the stretch modes for rows to fill extra allocated window space. See
  -colstretchmode for valid options.
  [-rowtagcommand rowTagCommand] Provides
  the name of a procedure that can evaluated by the widget to determine the tag
  to be used for a given row. The procedure must be defined by the user to
  accept a single argument (the row number), and return a tag name or null
  string. This operates in a similar manner as -coltagcommand, except
  that it applies to row tags. [-selectioncommand or
  -selcmd selectionCommand] Specifies a command to evaluate
  when the selection is retrieved from a table via the selection mechanism (ie:
  evaluating ``selection get''). The return value from this command will
  become the string passed on by the selection mechanism. It uses the
  %-substition model described in COMMAND SUBSTITUTION below. If an error
  occurs, a Tcl background error is generated and nothing is returned.
  [-selectmode selectMode] Specifies one
  of several styles for manipulating the selection. The value of the option may
  be arbitrary, but the default bindings expect it to be either single,
  browse, multiple, or extended; the default value is
  browse. These styles are like those for the Tk listbox, except expanded
  for 2 dimensions. [-selecttitle
  selectTitles] Specifies whether title cells should be allowed in
  the selection. Defaults to 0 (disallowed).
  [-selecttype selectType] Specifies one
  of several types of selection for the table. The value of the option may be
  one of row, col, cell, or both (meaning row
  && col); the default value is cell. These types define
  whether an entire row/col is affected when a cell's selection is changed (set
  or clear). [-sparsearray sparseArray] A
  boolean value that specifies whether an associated Tcl array should be kept as
  a sparse array (1, the default) or as a full array (0). If true, then cell
  values that are empty will be deleted from the array (taking less memory). If
  false, then all values in the array will be maintained.
  [-state state] Specifies one of two
  states for the entry: normal or disabled. If the table is
  disabled then the value may not be changed using widget commands and no
  insertion cursor will be displayed, even if the input focus is in the widget.
  Also, all insert or delete methods will be ignored. Defaults to normal.
  [-titlecols titleCols] Number of columns
  to use as a title area. Defaults to 0. [-titlerows
  titleRows] Number of rows to use as a title area. Defaults to 0.
  [-usecommand useCommand] A boolean value
  which specifies whether to use the command option. This value sets
  itself to zero if command is used and returns an error. Defaults to 1
  (will use command if specified). [-validate
  validate] A boolean specifying whether validation should occur
  for the active buffer. Defaults to 0. [-validatecommand or
  -vcmd validateCommand] Specifies a command to execute when
  the active cell is edited. This command is expected to return a Tcl boolean.
  If it returns true, then it is assumed the new value is OK, otherwise the new
  value is rejected (the edition will not take place). Errors in this command
  are handled in the background. It uses the %-substition model described in
  COMMAND SUBSTITUTION below. [-variable
  variable] Global Tcl array variable to attach to the table's C
  array. It will be created if it doesn't already exist or is a simple variable.
  Keys used by the table in the array are of the form row,col for
  cells and the special key active which contains the value of the active
  cell buffer. The Tcl array is managed as a sparse array (the table does not
  require that all valid indices have values). No stored value for an index is
  equivalent to the empty string, and clearing a cell will remove that index
  from the Tcl array, unless the -sparsearray options is set to 0.
  [-width width] Specifies the desired
  width for the window, in columns. If zero or less, then the desired width for
  the window is made just large enough to hold all the columns in the table. The
  width can be further limited by -maxwidth.
  [-wrap wrap] Specifies the default wrap
  value for tags. Defaults to 0.











The table command creates a 2-dimensional grid of cells.
    The table can use a Tcl array variable or Tcl command for data storage and
    retrieval, as well as optionally cache data in memory for speed. One of
    these data sources must be configured before any data is retained by
    the table. The widget has an active cell, the contents of which can be
    edited (when the state is normal). The widget supports a default style for
    the cells and also multiple tags, which can be used to change the
    style of a row, column or cell (see TAGS for details). A cell flash
    can be set up so that changed cells will change color for a specified amount
    of time ("blink"). Cells can have embedded images or windows, as
    described in TAGS and "EMBEDDED WINDOWS" respectively.


One or more cells may be selected as described below. If a table
    is exporting its selection (see -exportselection option), then it
    will observe the standard X11 protocols for handling the selection. See THE
    SELECTION for details.


It is not necessary for all the cells to be displayed in the table
    window at once; commands described below may be used to change the view in
    the window. Tables allow scrolling in both directions using the standard
    -xscrollcommand and -yscrollcommand options. They also support
    scanning, as described below.


In order to obtain good performance, the table widget supports
    multiple drawing modes, two of which are fully Tk compatible.










When the table command is loaded into an interpreter, a
    built-in Tcl command, tkTableInit, is evaluated. This will search for
    the appropriate table binding init file to load. The directories searched
    are those in $tcl_pkgPath, both with Tktable(version) appended and
    without, $tk_library and [pwd] (the current directory). You
    can also define an $env(TK_TABLE_LIBRARY) to head this search list.
    By default, the file searched for is called tkTable.tcl, but this can
    be overridden by setting $env(TK_TABLE_LIBRARY_FILE).


This entire init script can be overridden by providing your own
    tkTableInit procedure before the library is loaded. Otherwise, the
    aforementioned env(TK_TABLE_LIBRARY) variable will be set with the
    directory in which $env(TK_TABLE_LIBRARY_FILE) was found.










Many of the widget commands for tables take one or more indices as
    arguments. An index specifies a particular cell of the table, in any of the
    following ways:



  

  
Specifies the cell as a numerical index of row,col which corresponds to
      the index of the associated Tcl array, where -roworigin,-colorigin
      corresponds to the first cell in the table (0,0 by default). The values
      for row and column will be constrained to actual values in the table,
      which means a valid cell is always found.

  

  
Indicates the cell that has the location cursor. It is specified with the
      activate widget command.

  

  
Indicates the anchor point for the selection, which is set with the
      selection anchor widget command.

  

  
Indicates the bottom-rightmost cell visible in the table.

  

  
Indicates the bottom right cell of the table.

  

  
Indicates the top-leftmost editable cell of the table, not necessarily in
      the display. This takes into account the user specified origin and title
      area.

  

  
Indicates the top-leftmost editable cell visible in the table (this
      excludes title cells).

  
@x,y

  
Indicates the cell that covers the point in the table window specified by
      x and y (in pixel coordinates). If no cell covers that
      point, then the closest cell to that point is used.




In the widget command descriptions below, arguments named
    index, first, and last always contain text indices in
    one of the above forms.










A tag is a textual string that is associated with zero or more
    rows, columns or cells in a table. Tags may contain arbitrary characters,
    but it is probably best to avoid using names which look like indices to
    reduce coding confusion. A tag can apply to an entire row or column, or just
    a single cell. There are several permanent tags in each table that can be
    configured by the user and will determine the attributes for special
  cells:





  

  
This tag is given to the active cell

  

  
If flash mode is on, this tag is given to any recently edited cells.

  

  
This tag is given to any selected cells.

  

  
This tag is given to any cells in the title rows and columns. This tag has
      -state disabled by default.






Tags control the way cells are displayed on the screen. Where
    appropriate, the default for displaying cells is determined by the options
    for the table widget. However, display options may be associated with
    individual tags using the ``pathName tag configure'' widget
    command. If a cell, row or column has been tagged, then the display options
    associated with the tag override the default display style. The following
    options are currently supported for tags:





  

  
Anchor for item in the cell space.

  

  
Background color of the cell.

  

  
Borderwidth of the cell, of the same format for the table, but may also be
      empty to inherit the default table borderwidth value (the default).

  

  
String to display at the end of a line that would be clipped by its cell,
      like ``...''. An ellipsis will be displayed only on non-wrapping,
      non-multiline cells that would be clipped. The ellipsis will display on
      the left for east anchored cells, otherwise it displays on the right.

  

  
Font for text in the cell.

  

  
Foreground color of the cell.

  

  
How to justify multi-line text in a cell. It must be one of left,
      right, or center.

  

  
An image to display in the cell instead of text.

  

  
Whether to display text with newlines on multiple lines.

  

  
The relief for the cell. May be the empty string to cause this tag to not
      disturb the value.

  

  
Whether to show the text over an image.

  

  
The state of the cell, to allow for certain cells to be disabled. This
      prevents the cell from being edited by the insert or delete
      methods, but a direct set will not be prevented.

  

  
Whether characters should wrap in a cell that is not wide enough.






A priority order is defined among tags based on creation order
    (first created tag has highest default priority), and this order is used in
    implementing some of the tag-related functions described below. When a cell
    is displayed, its properties are determined by the tags which are assigned
    to it. The priority of a tag can be modified by the ``pathName
    tag lower'' and ``pathName tag raise''
    widget commands.


If a cell has several tags associated with it that define the same
    display options (eg - a title cell with specific row and
    cell tags), then the options of the highest priority tag are used. If
    a particular display option hasn't been specified for a particular tag, or
    if it is specified as an empty string, then that option will not be used;
    the next-highest-priority tag's option will be used instead. If no tag
    specifies a particular display option, then the default style for the widget
    will be used.


Images are used for display purposes only. Editing in that cell
    will still be enabled and any querying of the cell will show the text value
    of the cell, regardless of the value of -showtext.










There may be any number of embedded windows in a table widget (one
    per cell), and any widget may be used as an embedded window (subject to the
    usual rules for geometry management, which require the table window to be
    the parent of the embedded window or a descendant of its parent). The
    embedded window's position on the screen will be updated as the table is
    modified or scrolled, and it will be mapped and unmapped as it moves into
    and out of the visible area of the table widget. Each embedded window
    occupies one cell's worth of space in the table widget, and it is referred
    to by the index of the cell in the table. Windows associated with the table
    widget are destroyed when the table widget is destroyed.


Windows are used for display purposes only. A value still exists
    for that cell, but will not be shown unless the window is deleted in some
    way. If the window is destroyed or lost by the table widget to another
    geometry manager, then any data associated with it is lost (the cell it
    occupied will no longer appear in window names).


When an embedded window is added to a table widget with the window
    configure widget command, several configuration options may be associated
    with it. These options may be modified with later calls to the window
    configure widget command. The following options are currently supported:





  

  
NOT CURRENTLY SUPPORTED. Specifies a Tcl script that may be evaluated to
      create the window for the annotation. If no -window option has been
      specified for this cell then this script will be evaluated when the cell
      is about to be displayed on the screen. Script must create a window for
      the cell and return the name of that window as its result. If the cell's
      window should ever be deleted, the script will be evaluated again the next
      time the cell is displayed.

  

  
Background color of the cell. If not specified, it uses the table's
      default background.

  

  
Borderwidth of the cell, of the same format for the table, but may also be
      empty to inherit the default table borderwidth value (the default).

  

  
As defined in the Tk options man page.

  

  
As defined in the Tk options man page.

  

  
The relief to use for the cell in which the window lies. If not specified,
      it uses the table's default relief.

  

  
Stickiness of the window inside the cell, as defined by the grid
      command.

  

  
Specifies the name of a window (widget) to display in the annotation. It
      must exist before being specified here. When an empty string is specified,
      if a window was displayed it will cease to be managed by the table
    widget.














Table selections are available as type STRING. By default, the
    value of the selection will be the values of the selected cells in nested
    Tcl list form where each row is a list and each column is an element of a
    row list. You can change the way this value is interpreted by setting the
    -rowseparator and -colseparator options. For example, default
    Excel format would be to set -rowseparator to '\n' and
    -colseparator to '\t'. Changing these values affects both how the
    table sends out the selection and reads in pasted data, ensuring that the
    table should always be able to cut and paste to itself. It is possible to
    change how pastes are handled by editing the table library procedure
    tk_tablePasteHandler. This might be necessary if
    -selectioncommand is set.










Individual cells can span multiple rows and/or columns. This is
    done via the spans command (see below for exact arguments). Cells in
    the title area that span are not permitted to span beyond the title area,
    and will be constrained accordingly. If the title area shrinks during a
    configure, sanity checking will occur to ensure the above. You may set spans
    on regular cells that extend beyond the defined row/col area. These spans
    will not be constrained, so that when the defined row/col area expands, the
    span will expand with it.


When setting a span, checks are made as to whether the span would
    overlap an already spanning or hidden cell. This is an error and it not
    allowed. Spans can affect the overall speed of table drawing, although not
    significantly. If spans are not used, then there is no performance loss.


Cells hidden by spanning cells still have valid data. This
    will be seen during cut and paste operations that involve hidden cells, or
    through direct access by a command like get or set.


The drawing properties of spanning cells apply to only the visual
    area of the cell. For example, if a cell is center justified over 5 columns,
    then when viewing any portion of those columns, it will appear centered in
    the visible area. The non-visible column area will not be considered in the
    centering calculations.










The various option based commands that the table supports all
    support the familiar Tk %-substitution model (see bind for more
    details). The following %-sequences are recognized and substituted by the
    table widget:



  
%c

  
For SelectionCommand, it is the maximum number of columns in any
      row in the selection. Otherwise it is the column of the triggered
    cell.

  
%C

  
A convenience substitution for %r,%c.

  
%i

  
For SelectionCommand, it is the total number of cells in the
      selection. For Command, it is 0 for a read (get) and 1 for a write
      (set). Otherwise it is the current cursor position in the cell.

  
%r

  
For SelectionCommand, it is the number of rows in the selection.
      Otherwise it is the row of the triggered cell.

  
%s

  
For ValidateCommand, it is the current value of the cell being
      validated. For SelectionCommand, it is the default value of the
      selection. For BrowseCommand, it is the index of the last active
      cell. For Command, it is empty for reads (get) and the current
      value of the cell for writes (set).

  
%S

  
For ValidateCommand, it is the potential new value of the cell
      being validated. For BrowseCommand, it is the index of the new
      active cell.

  
%W

  
The pathname to the window for which the command was generated.










The table command creates a new Tcl command whose name is
    pathName. This command may be used to invoke various operations on
    the widget. It has the following general form:




pathName option ?arg arg ...?



Option and the args determine the exact behavior of the command.

The following commands are possible for table widgets:



  

  
Sets the active cell to the one indicated by index.

  

  
It returns the bounding box for the specified cell (range) as a 4-tuple of
      x, y, width and height in pixels. It clips the box to the visible portion,
      if any, otherwise an empty string is returned.

  

  
This command is a voodoo hack to implement border sizing for tables. This
      is normally called through bindings, with the following as valid
    options:







  

  
Records x and y and the row and/or column border under that
      point in the table window, if any; used in conjunction with later
      border dragto commands. Typically this command is associated
      with a mouse button press in the widget. If row or col is
      not specified, it returns a tuple of both border indices (an empty item
      means no border). Otherwise, just the specified item is returned.

  

  
This command computes the difference between its x and y
      arguments and the x and y arguments to the last
      border mark command for the widget. It then adjusts the
      previously marked border by the difference. This command is typically
      associated with mouse motion events in the widget, to produce the effect
      of interactive border resizing.







  

  
Returns the current value of the configuration option given by
      option. Option may have any of the values accepted by the
      table command.

  

  
This command is a convenience routine to clear certain state information
      managed by the table. first and last represent valid table
      indices. If neither are specified, then the command operates on the whole
      table. The following options are recognized:







  

  
Clears the specified section of the cache, if the table has been keeping
      one.

  

  
Clears the specified row and column areas of specific height/width
      dimensions. When just one index is specified, for example 2,0, that
      is interpreted as row 2 and column 0.

  

  
Clears the specified area of tags (all row, column and cell tags).

  

  
Performs all of the above clear functions on the specified area.







  

  
Query or modify the configuration options of the widget. If no
      option is specified, returns a list describing all of the available
      options for pathName (see Tk_ConfigureInfo for information
      on the format of this list). If option is specified with no
      value, then the command returns a list describing the one named
      option (this list will be identical to the corresponding sublist of the
      value returned if no option is specified). If one or more
      option-value pairs are specified, then the command modifies the
      given widget option(s) to have the given value(s); in this case the
      command returns an empty string. Option may have any of the values
      accepted by the table command.

  

  
With no arguments, it returns the sorted indices of the currently selected
      cells. Otherwise it sets all the selected cells to the given value. The
      set has no effect if there is no associated Tcl array or the state is
      disabled.

  

  
If no value is given, the value of the cell being edited (indexed by
      active) is returned, else it is set to the given value.

  

  
This command is used to delete various things in a table. It has several
      forms, depending on the option:







  

  
Deletes text from the active cell. If only one index is given, it deletes
      the character after that index, otherwise it deletes from the first index
      to the second. index can be a number, insert or
    end.

  

  
Deletes count cols starting at (and including) col index.
      The index will be constrained to the limits of the tables. If
      count is negative, it deletes cols to the left. Otherwise it
      deletes cols to the right. count defaults to 1 (meaning just the
      column specified). At the moment, spans are not adjusted with this action.
      Optional switches are:







  

  
Causes the table cols to be unaffected by the deletion (empty cols may
      appear). By default the dimensions are adjusted by count.

  

  
Causes the selection to be maintained on the absolute cells values.
      Otherwise, the selection will be cleared..

  

  
Causes the tags specified by the tag method to not move along with
      the data. Also prevents specific widths set by the width method
      from being adjusted. By default, these tags are properly adjusted.

  

  
Causes the embedded windows created with the window method to not
      move along with the data. By default, these windows are properly
    adjusted.

  

  
Prevents title area cells from being changed. Otherwise they are treated
      just like regular cells and will move as specified.

  
--

  
Signifies the end of the switches.







  

  
Deletes count rows starting at (and including) row index. If
      count is negative, it deletes rows going up. Otherwise it deletes
      rows going down. The selection will be cleared. The switches are the same
      as those for column deletion.







  

  
Returns the value of the cells specified by the table indices first
      and (optionally) last in a list.

  

  
If no row is specified, returns a list describing all rows for
      which a height has been set. If row is specified with no value, it
      prints out the height of that row in characters (positive number) or
      pixels (negative number). If one or more row-value pairs are
      specified, then it sets each row to be that height in lines (positive
      number) or pixels (negative number). If value is default,
      then the row uses the default height, specified by -rowheight.

  

  
When called without args, it returns all the hidden cells (those
      cells covered by a spanning cell). If one index is specified, it returns
      the spanning cell covering that index, if any. If multiple indices are
      specified, it returns 1 if all indices are hidden cells, 0 otherwise.

  

  
With no arguments, prints out the location of the insertion cursor in the
      active cell. With one argument, sets the cursor to that point in the
      string. 0 is before the first character, you can also use insert or
      end for the current insertion point or the end of the text. If
      there is no active cell, or the cell or table is disabled, this will
      return -1.

  

  
Returns the integer cell coordinate that corresponds to index in
      the form row,col. If row or col is specified, then only the
      row or column index is returned.

  

  
This command is used to into various things into a table. It has several
      forms, depending on the option:







  

  
The value is a text string which is inserted at the index
      position of the active cell. The cursor is then positioned after the new
      text. index can be a number, insert or end.

  

  
Inserts count cols starting at col index. If count is
      negative, it inserts before the specified col. Otherwise it inserts after
      the specified col. The selection will be cleared. The switches are the
      same as those for column deletion.

  

  
Inserts count rows starting at row index. If count is
      negative, it inserts before the specified row. Otherwise it inserts after
      the specified row. The selection will be cleared. The switches are the
      same as those for column deletion.







  

  
Rereads the old contents of the cell back into the editing buffer. Useful
      for a key binding when <Escape> is pressed to abort the edit (a
      default binding).

  

  
This command is used to implement scanning on tables. It has two forms,
      depending on option:







  

  
Records x and y and the current view in the table window;
      used in conjunction with later scan dragto commands. Typically this
      command is associated with a mouse button press in the widget. It returns
      an empty string.

  

  
This command computes the difference between its x and y
      arguments and the x and y arguments to the last scan
      mark command for the widget. It then adjusts the view by 5 times the
      difference in coordinates. This command is typically associated with mouse
      motion events in the widget, to produce the effect of dragging the list at
      high speed through the window. The return value is an empty string.







  

  
Adjust the view in the table so that the cell given by index is
      positioned as the cell one off from top left (excluding title rows and
      columns) if the cell is not currently visible on the screen. The actual
      cell may be different to keep the screen full.

  

  
This command is used to adjust the selection within a table. It has
      several forms, depending on option:







  

  
Sets the selection anchor to the cell given by index. The selection
      anchor is the end of the selection that is fixed while dragging out a
      selection with the mouse. The index anchor may be used to refer to
      the anchor cell.

  

  
If any of the cells between first and last (inclusive) are
      selected, they are deselected. The selection state is not changed for
      cells outside this range. first may be specified as all to
      remove the selection from all cells.

  

  
Returns 1 if the cell indicated by index is currently selected, 0
      if it isn't.

  

  
Selects all of the cells in the range between first and
      last, inclusive, without affecting the selection state of cells
      outside that range.







  

  
Sets the specified index to the associated value. Table validation will
      not be triggered via this method. If row or col precedes the
      list of index/value pairs, then the value is assumed to be a Tcl list
      whose values will be split and set into the subsequent columns (if
      row is specified) or rows (for col). For example, set row
      2,3 {2,3 2,4 2,5} will set 3 cells, from 2,3 to 2,5. The
      setting of cells is silently bounded by the known table dimensions.

  

  
This command is used to manipulate row/col spans. When called with no
      arguments, all known spans are returned as a list of tuples of the form
      {index span}. When called with only the index, the span for that
      index only is returned, if any. Otherwise an even number of
      index rows,cols pairs are used to set spans. A span starts at the
      index and continues for the specified number of rows and cols.
      Negative spans are not supported. A span of 0,0 unsets any span on that
      cell. See EXAMPLES for more info.

  

  
This command is used to manipulate tags. The exact behavior of the command
      depends on the option argument that follows the tag
      argument. cget, cell, and row|col complain about
      unknown tag names. The following forms of the command are currently
      supported:







  

  
With no arguments, prints out the list of cells that use the tag.
      Otherwise it sets the specified cells to use the named tag, replacing any
      tag that may have been set using this method before. If tagName is
      {}, the cells are reset to the default tag. Tags added during
      -*tagcommand evaluation do not register here. If tagName does not
      exist, it will be created with the default options.

  

  
This command returns the current value of the option named option
      associated with the tag given by tagName. Option may have
      any of the values accepted by the tag configure widget
    command.

  

  
With no arguments, prints out the list of cols that use the tag.
      Otherwise it sets the specified columns to use the named tag, replacing
      any tag that may have been set using this method before. If tagName
      is {}, the cols are reset to the default tag. Tags added during
      -coltagcommand evaluation do not register here. If tagName does not
      exist, it will be created with the default options.

  

  
This command is similar to the configure widget command except that
      it modifies options associated with the tag given by tagName
      instead of modifying options for the overall table widget. If no
      option is specified, the command returns a list describing all of
      the available options for tagName (see Tk_ConfigureInfo for
      information on the format of this list). If option is specified
      with no value, then the command returns a list describing the one
      named option (this list will be identical to the corresponding sublist of
      the value returned if no option is specified). If one or more
      option-value pairs are specified, then the command modifies the
      given option(s) to have the given value(s) in tagName; in this case
      the command returns an empty string. See TAGS above for details on the
      options available for tags.

  

  
Deletes a tag. No error if the tag does not exist.

  

  
Returns 1 if the named tag exists, 0 otherwise.

  

  
Returns 1 if the specified index has the named tag, 0 otherwise.

  

  
Lower the priority of the named tag. If belowThis is not specified,
      then the tag's priority is lowered to the bottom, otherwise it is lowered
      to one below belowThis.

  

  
If no pattern is specified, shows the names of all defined tags. Otherwise
      the pattern is used as a glob pattern to show only tags matching
      that pattern. Tag names are returned in priority order (highest priority
      tag first).

  

  
Raise the priority of the named tag. If aboveThis is not specified,
      then the tag's priority is raised to the top, otherwise it is raised to
      one above aboveThis.

  

  
With no arguments, prints out the list of rows that use the tag.
      Otherwise it sets the specified rows to use the named tag, replacing any
      tag that may have been set using this method before. If tagName is
      {}, the rows are reset to use the default tag. Tags added during
      -rowtagcommand evaluation do not register here. If tagName does not
      exist, it will be created with the default options.







  

  
Explicitly validates the specified index based on the current
      -validatecommand and returns 0 or 1 based on whether the cell was
      validated.

  

  
If no col is specified, returns a list describing all cols for
      which a width has been set. If col is specified with no value, it
      prints out the width of that col in characters (positive number) or pixels
      (negative number). If one or more col-value pairs are specified,
      then it sets each col to be that width in characters (positive number) or
      pixels (negative number). If value is default, then the col
      uses the default width, specified by -colwidth.

  

  
This command is used to manipulate embedded windows. The exact behavior of
      the command depends on the option argument that follows the
      window argument. The following forms of the command are currently
      supported:







  

  
This command returns the current value of the option named option
      associated with the window given by index. Option may have
      any of the values accepted by the window configure widget
    command.

  

  
This command is similar to the configure widget command except that
      it modifies options associated with the embedded window given by
      index instead of modifying options for the overall table widget. If
      no option is specified, the command returns a list describing all
      of the available options for index (see Tk_ConfigureInfo for
      information on the format of this list). If option is specified
      with no value, then the command returns a list describing the one
      named option (this list will be identical to the corresponding sublist of
      the value returned if no option is specified). If one or more
      option-value pairs are specified, then the command modifies the
      given option(s) to have the given value(s) in index; in this case
      the command returns an empty string. See EMBEDDED WINDOWS above for
      details on the options available for windows.

  

  
Deletes an embedded window from the table. The associated window will also
      be deleted.

  

  
Moves an embedded window from one cell to another. If a window already
      exists in the target cell, it will be deleted.

  

  
If no pattern is specified, shows the cells of all embedded windows.
      Otherwise the pattern is used as a glob pattern to show only cells
      matching that pattern.







  

  
This command is used to query and change the horizontal position of the
      information in the widget's window. It can take any of the following
      forms:







  

  
Returns a list containing two elements. Each element is a real fraction
      between 0 and 1; together they describe the horizontal span that is
      visible in the window. For example, if the first element is .2 and the
      second element is .6, 20% of the table's text is off-screen to the left,
      the middle 40% is visible in the window, and 40% of the text is off-screen
      to the right. These are the same values passed to scrollbars via the
      -xscrollcommand option.

  

  
Adjusts the view in the window so that the column given by index is
      displayed at the left edge of the window.

  

  
Adjusts the view in the window so that fraction of the total width
      of the table text is off-screen to the left. fraction must be a
      fraction between 0 and 1.

  

  
This command shifts the view in the window left or right according to
      number and what. Number must be an integer.
      What must be either units or pages or an abbreviation
      of one of these. If what is units, the view adjusts left or
      right by number cells on the display; if it is pages then
      the view adjusts by number screenfuls. If number is negative
      then cells farther to the left become visible; if it is positive then
      cells farther to the right become visible.







  

  
This command is used to query and change the vertical position of the text
      in the widget's window. It can take any of the following forms:







  

  
Returns a list containing two elements, both of which are real fractions
      between 0 and 1. The first element gives the position of the table element
      at the top of the window, relative to the table as a whole (0.5 means it
      is halfway through the table, for example). The second element gives the
      position of the table element just after the last one in the window,
      relative to the table as a whole. These are the same values passed to
      scrollbars via the -yscrollcommand option.

  

  
Adjusts the view in the window so that the row given by index is
      displayed at the top of the window.

  

  
Adjusts the view in the window so that the element given by
      fraction appears at the top of the window. Fraction is a
      fraction between 0 and 1; 0 indicates the first element in the table, 0.33
      indicates the element one-third the way through the table, and so on.

  

  
This command adjusts the view in the window up or down according to
      number and what. Number must be an integer.
      What must be either units or pages. If what is
      units, the view adjusts up or down by number cells; if it is
      pages then the view adjusts by number screenfuls. If
      number is negative then earlier elements become visible; if it is
      positive then later elements become visible.














The initialization creates class bindings that give the following
    default behaviour:



  
[1]

  
Clicking Button-1 in a cell activates that cell. Clicking into an already
      active cell moves the insertion cursor to the character nearest the
    mouse.

  
[2]

  
Moving the mouse while Button-1 is pressed will stroke out a selection
      area. Exiting while Button-1 is pressed causing scanning to occur on the
      table along with selection.

  
[3]

  
Moving the mouse while Button-2 is pressed causes scanning to occur
      without any selection.

  
[4]

  
Home moves the table to have the origin in view.

  
[5]

  
End moves the table to have the end cell in view.

  
[6]

  
Control-Home moves the table to the origin and activates that cell.

  
[7]

  
Control-End moves the table to the end and activates that cell.

  
[8]

  
Shift-Control-Home extends the selection to the origin.

  
[9]

  
Shift-Control-End extends the selection to the end.

  
[10]

  
The left, right, up and down arrows move the active cell.

  
[11]

  
Shift-<arrow> extends the selection in that direction.

  
[12]

  
Control-leftarrow and Control-rightarrow move the insertion cursor within
      the cell.

  
[13]

  
Control-slash selects all the cells.

  
[14]

  
Control-backslash clears selection from all the cells.

  
[15]

  
Backspace deletes the character before the insertion cursor in the active
      cell.

  
[16]

  
Delete deletes the character after the insertion cursor in the active
      cell.

  
[17]

  
Escape rereads the value of the active cell from the specified data
      source, discarding any edits that have may been performed on the
    cell.

  
[18]

  
Control-a moves the insertion cursor to the beginning of the active
    cell.

  
[19]

  
Control-e moves the insertion cursor to the end of the active cell.

  
[20]

  
Control-minus and Control-equals decrease and increase the width of the
      column with the active cell in it.

  
[21]

  
Moving the mouse while Button-3 (the right button on Windows) is pressed
      while you are over a border will cause interactive resizing of that row
      and/or column to occur, based on the value of -resizeborders.




Some bindings may have slightly different behavior dependent on
    the -selectionmode of the widget.


If the widget is disabled using the -state option, then its
    view can still be adjusted and cells can still be selected, but no insertion
    cursor will be displayed and no cell modifications will take place.


The behavior of tables can be changed by defining new bindings for
    individual widgets or by redefining the class bindings. The default bindings
    are either compiled in or read from a file expected to correspond to:
    "[lindex $tcl_pkgPath 0]/Tktable<version>/tkTable.tcl".










The number of rows and columns or a table widget should not
    significantly affect the speed of redraw. Recalculation and redraw of table
    parameters and cells is restricted as much as possible.


The display cell with the insert cursor is redrawn each time the
    cursor blinks, which causes a steady stream of graphics traffic. Set the
    -insertofftime option to 0 avoid this. The use of a -command
    with the table without a cache can cause significant slow-down, as the
    command is called once for each request of a cell value.












Set the topleft title area to be one spanning cell. This
    overestimates both row and column span by one, but the command does all the
    constraining for us.




$table span [$table cget -roworigin],[$table cget -colorigin] [$table cget -titlerows],[$table cget -titlecols]



Force a table window refresh (useful for the slight chance that a bug in the
  table is not causing proper refresh):



$table configure -padx [$table cget -padx]
