<H2><A NAME="sect2" HREF="#toc2">Description</A></H2>
The <B>table</B> command
arranges widgets in a table.  The alignment of widgets is determined by their
row and column positions and the number of rows or columns that they span.

<H2><A NAME="sect3" HREF="#toc3">Introduction</A></H2>
Probably the most painstaking aspect of building a graphical
application is getting the placement and size of the widgets just right.
It usually takes many iterations to align widgets and adjust their spacing.
That's because managing the geometry of widgets is simply not a packing
problem, but also graphical design problem.  Attributes such as alignment,
symmetry, and balance are more important than minimizing the amount of
space used for packing. <P>
The <B>table</B> geometry manager arranges widgets in a
table.  It's easy to align widgets (horizontally and vertically) or to create
empty space to balance the arrangement of the widgets.  Widgets (called
<I>slaves</I> in the Tk parlance) are arranged inside a containing widget (called
the <I>master</I>).  Widgets are positioned at row,column locations and may span
any number of rows or columns.  More than one widget can occupy a single
location. <P>
The placement of widget windows determines both the size and arrangement
of the table.  The table queries the requested size of each widget.  The
<I>requested size</I> of a widget is the natural size of the widget (before the
widget is shrunk or expanded).  The height of each row and the width of
each column is the largest widget spanning that row or column.  The size
of the table is in turn the sum of the row and column sizes.  This is the
table's <I>normal size</I>. <P>
The total number of rows and columns in a table is determined
from the indices specified.  The table grows dynamically as windows are
added at larger indices. 
<H2><A NAME="sect4" HREF="#toc4">Example</A></H2>
The table geometry manager is created by
invoking the <B>table</B> command. <BR>
<CODE># Create a table in the root window<BR>
table .<BR>
</CODE><P>The window <I>.</I> is now the <I>container</I> of the table.  Widgets are packed into
the table and displayed within the confines of the container. <P>
You add widgets
to the table by row and column location.  Row and column indices start from
zero. <BR>
<CODE>label .title -text "This is a title"<BR>
<P>
# Add a label to the table<BR>
table . .title 0,0 <BR>
</CODE><P>The label <I>.title</I> is added to the table.  We can add more widgets in the same
way. <BR>
<CODE>button .ok -text "Ok"<BR>
button .cancel -text "Cancel"<BR>
<P>
# Add two buttons<BR>
table . .ok 1,0<BR>
table . .cancel 1,1<BR>
</CODE><P>Two buttons <I>.ok</I> and <I>.cancel</I> are now packed into the second row of the table.
 They each occupy one cell of the table.  By default, widgets span only
a single row and column. <P>
The first column contains two widgets, <I>.title</I> and
<I>.ok</I>.  By default, the widest of the two widgets will define the width of
the column.  However, we want <I>.title</I> to be centered horizontally along the
top of the table.  We can make <I>.title</I> span two columns using the <B>configure</B>
operation. <BR>
<CODE># Make the label span both columns<BR>
table configure . .title -cspan 2<BR>
</CODE><P>The label <I>.title</I> will now be centered along the top row of the table.   <P>
In
the above example, we've create and arranged the layout for the table invoking
the <B>table</B> command several times.  Alternately, we could have used a single
<B>table</B> command. <BR>
<CODE>label .title -text "This is a title"<BR>
button .ok -text "Ok"<BR>
button .cancel -text "Cancel"<BR>
<P>
# Create and pack the table<BR>
table . \<BR>
    .title  0,0 -cspan 2 \<BR>
    .ok     1,0 \<BR>
    .cancel 1,1<BR>
</CODE><P>The table will override the requested width and height of the container
so that the window fits the table exactly.  This also means that any change
to the size of table will be propagated up through the Tk window hierarchy.
 This feature can be turned off using the <B>configure</B> operation again. <BR>
<CODE>table configure . -propagate no<BR>
</CODE><P>You can also set the width of height of the table to a specific value. This
supersedes the calculated table size. <BR>
<CODE># Make the container 4 inches wide, 3 inches high<BR>
table configure . -reqwidth 4i -reqheight 3i<BR>
</CODE><P>If a widget is smaller than the cell(s) it occupies, the widget will float
within the extra space.  By default, the widget will be centered within
the space, but you can anchor the widget to any side of cell using the
<B>-anchor</B> configuration option. <BR>
<CODE>table configure . .ok -anchor w<BR>
</CODE><P>The <B>-fill</B> option expands the widget to fill the  extra space either vertically
or horizontally (or both). <BR>
<CODE># Make the title label fill the entire top row<BR>
table configure . .title -cspan 2 -fill x <BR>
<P>
# Each button will be as height of the 2nd row.<BR>
table configure . .ok .cancel -fill y<BR>
</CODE><P>The width of <I>.title</I> will be the combined widths of both columns. Both <I>.ok</I>
and <I>.cancel</I> will become as tall as the second row.   <P>
The <B>-padx</B> and <B>-pady</B> options
control the amount of padding  around the widget.  Both options take a list
of one or two values. <BR>
<CODE># Pad the title by two pixels above and below.<BR>
table configure . .title -pady 2<BR>
<P>
# Pad each button 2 pixels on the left, and 4 on the right.<BR>
table configure . .ok .cancel -padx { 2 4 }<BR>
</CODE><P>If the list has only one value, then both exterior sides (top and bottom
or left and right) of the widget are padded by that amount.  If the list
has two elements, the first specifies padding for the top or left side
and the second for the bottom or right side. <P>
Like the container, you can
also override the requested widths and heights of widgets using the <B>-reqwidth</B>
and <B>-reqheight</B> options.  This is especially useful with character-based widgets
(such as buttons, labels, text, listbox, etc) that let you specify their
size only in units of characters and lines, instead of pixels. <BR>
<CODE># Make all buttons one inch wide<BR>
table configure . .ok .cancel -reqwidth 1i<BR>
<P>
</CODE><P>Each row and column of the table can be configured, again using the <B>configure</B>
operation.  Rows are and columns are designated by <I>R<I>i</I></I> and <I>C<I>i</I></I> respectively,
where <I>i</I> is the index of the row or column. <P>
For example, you can set the
size of a row or column. <BR>
<CODE># Make the 1st column 2 inches wide<BR>
table configure . c0 -width 2.0i<BR>
<P>
# Make the 2nd row 1/2 inch high.<BR>
table configure . r1 -height 0.5i<BR>
</CODE><P>The new size for the row or column overrides its calculated size.  If no
widgets span the row or column, its height or width is zero. So you can
use the <B>-width</B> and <B>-height</B> options to create empty spaces in the table. <BR>
<CODE># Create an empty row and column<BR>
table configure . r2 c2 -width 1i<BR>
</CODE><P>The <B>-pady</B> option lets you add padding to the top and bottom sides of rows.
 The <B>-padx</B> option adds padding to the left and right sides of columns.  Both
options take a list of one or two values. <BR>
<CODE># Pad above the title by two pixels <BR>
table configure . r0 -pady { 2 0 }<BR>
<P>
# Pad each column 4 pixels on the left, and 2 on the right.<BR>
table configure . c* -padx { 2 4 }<BR>
<P>
</CODE><P>Notice that you can configure all the rows and columns using either <I>R*</I>
or <I>C*</I>. <P>
When the container is resized, the rows and columns of the table
are also resized.  Only the rows or columns that contain widgets (a widget
spans the row or column) grow or shrink.  The <B>-resize</B> option indicates whether
the row or column can be shrunk or stretched.  If the value is <I>shrink</I>, the
row or column can only be resized smaller.  If <I>expand</I>, it can only be resized
larger.  If <I>none</I>, the row or column is frozen at its requested size. <BR>
<CODE># Let the 1st column get smaller, but not bigger<BR>
table configure . c0 -resize shrink<BR>
<P>
# Let the 2nd column get bigger, not smaller<BR>
table configure . c1 -resize expand<BR>
<P>
# Don't resize the first row <BR>
table configure . r0 -resize none<BR>
</CODE><P>The following example packs a canvas, two scrollbars, and a title. The rows
and columns containing the scrollbars are frozen at their requested size,
so that even if the frame is resized, the scrollbars will remain the same
width. <BR>
<CODE>table . \<BR>
    .title   0,0 -cspan 3 \<BR>
    .canvas  1,1 -fill both \<BR>
    .vscroll 1,2 -fill y \<BR>
    .hscroll 2,1 -fill x<BR>
<P>
# Don't let the scrollbars resize<BR>
table configure . c2 r2 -resize none<BR>
<P>
# Create an empty space to balance the scrollbar<BR>
table configure . c0 -width .vscroll<BR>
</CODE><P>Note that the value of the <B>-width</B> option is the name of a widget window.
 This indicates that the width of the column should be the same as the
requested width of <I>.vscroll</I>. <P>
Finally, the <B>forget</B> operation removes widgets
from the table. <BR>
<CODE># Remove the windows from the table<BR>
table forget .quit .frame<BR>
</CODE><P>It's not necessary to specify the container.  The <B>table</B> command determines
the container from the widget name. 
<H2><A NAME="sect5" HREF="#toc5">Operations</A></H2>
The following operations are
available for the <B>table</B>: 
<DL>

<DT><B>table <I>container</I></B> ?<I>widget index option value</I>?...  
</DT>
<DD>Adds the widget <I>widget</I> to the table at <I>index</I>.  <I>Index</I> is a row,column position
in the table.  It must be in the form <I>row</I>,<I>column</I> where <I>row</I> and <I>column</I> are
the respective row and column numbers, starting from zero (0,0 is the upper
leftmost position).  <I>Row</I> and <I>column</I> may also be numeric expressions that
are recursively evaluated.  If a table doesn't exist for <I>container</I>, one is
created.  <I>Widget</I> is the path name of the window, that must already exist,
to be arranged inside of <I>container</I>. <I>Option</I> and <I>value</I> are described in the
 <FONT SIZE=-1><B>WIDGET</B></FONT>
  section. </DD>

<DT><B>table arrange</B> <I>container</I> </DT>
<DD>Forces the table to compute its
layout immediately.  Normally, the table geometry manager will wait until
the next idle point, before calculating the size of its rows and columns.
 This is useful for collecting the <I>normal</I> sizes of rows and columns, that
are based upon the requested widget sizes. </DD>

<DT><B>table cget</B> <I>container </I>?<I>item</I>?<I> option</I>
</DT>
<DD>Returns the current value of the configuration option specific to <I>item</I>
given by <I>option</I>.  <I>Item</I> is either a row or column index, or the path name
of a widget.  <I>Item</I> can be in any form describe in the <B>configure</B> operation
below. If no <I>item</I> argument is provided, then the configuration option is
for the table itself.  <I>Option</I> may be any one of the options described in
the appropriate section for <I>item</I>. </DD>

<DT><B>table configure</B> <I>container item</I>... ?<I>option
value</I>?...  </DT>
<DD>Queries or modifies the configuration options specific to <I>item</I>.
If no <I>option</I> is specified, this command returns a list describing all of
the available options for <I>item</I>  If the argument <I>item</I> is omitted, then the
specified  configuration options are for the table itself.  Otherwise <I>item</I>
must be either a row or column specification, or the path name of a widget.
  The following <I>item</I> types are available. <blockquote></DD>

<DT><I>C<I>i</I></I> </DT>
<DD>Specifies the column of <I>container</I>
to be configured.  <I>Item</I> must be in the form <I>C<I>n</I></I>, where <I>i</I> is the index of
 the column.  See the  <FONT SIZE=-1><B>COLUMN</B></FONT>
  section. </DD>

<DT><I>R<I>i</I></I> </DT>
<DD>Specifies the row of <I>container</I>
to be configured. <I>Item</I> must be in the form <I>R<I>i</I></I>, where <I>i</I> is the index of the
row.  See the <FONT SIZE=-1><B>ROW</B></FONT>
  section. </DD>

<DT><I>widget</I>  </DT>
<DD>Specifies a widget of <I>container</I> to be
queried.  <I>Widget</I> is the path name of a widget packed in <I>container</I>.  See the
<FONT SIZE=-1><B>WIDGET</B></FONT>
  section. </DD>

<DT>No argument </DT>
<DD>Specifies that the table itself is to be queried.
  See the <FONT SIZE=-1><B>TABLE</B></FONT>
  section for a description of the option-value pairs for
the table. </DD>
</DL>
</blockquote>
<blockquote><P>
The <I>option<I> and <I>value</I></I></I> pairs are specific to <I>item</I>.  If <I>option</I> is
specified with no <I>value</I>, 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 <I>option</I> is specified).  If one or more <I>option-value</I>
pairs are specified, then the command modifies the given option(s) to have
the given value(s); in this case the command returns the empty string. </blockquote>

<DL>

<DT><B>table

the top and bottom exteriors of <I>widget</I>.  <I>Pad</I> can be a list of one or two
numbers.  If <I>pad</I> has two elements, the area above <I>widget</I> is padded by the
first value and the area below by the second value.  If <I>pad</I> is just one
number, both the top and bottom areas are padded by the value.  The default
is <I>0</I>. </DD>

<DT><B>-reqheight <I>height</I></B> </DT>
<DD>Specifies the limits of the requested height for
<I>widget</I>. <I>Height</I> is a list of bounding values.  See the  <FONT SIZE=-1><B>BOUNDING</B></FONT>
  section
for a description of this list.  By default, the height of <I>widget</I> is its
requested height with its internal padding (see the <B>-ipady</B> option).  The
bounds specified by <I>height</I> either override the height completely, or bound
the height between two sizes. The default is <I>""</I>. </DD>

<DT><B>-reqwidth <I>width</I></B> </DT>
<DD>Specifies
the limits of the requested width for <I>widget</I>. <I>Width</I> is a list of bounding
values.  See the  <FONT SIZE=-1><B>BOUNDING</B></FONT>
  section for a description of this list.  By default,
the width of <I>widget</I> is its requested width with its internal padding (set
the <B>-ipadx</B> option).  The bounds specified by <I>width</I> either override the width
completely, or bound the height between two sizes. The default is <I>""</I>. </DD>

<DT><B>-rowspan
<I>number</I></B> </DT>
<DD>Sets the number of rows <I>widget</I> will span. The default is <I>1</I>. </DD>

<DT><B>-rowcontrol
<I>control</I></B> </DT>
<DD>Specifies how the height of <I>widget</I> should control the height of
the rows it spans. <I>Control</I> is  either <I>normal</I>, <I>none</I>, or <I>full</I>.   The default
is <I>normal</I>. <blockquote></DD>

<DT><I>none</I> </DT>
<DD>The height of <I>widget</I> is not considered.    </DD>

<H2><A NAME="sect10" HREF="#toc10">Bounding Sizes</A></H2>
Sometimes it's more useful
to limit resizes to an acceptable range, than to fix the size to a particular
value or disallow resizing altogether.  Similar to the way the <B>wm</B> command
lets you specify a <B>minsize</B> and <B>maxsize</B> for a toplevel window, you can bound
the sizes the container, a widget, row, or column may take. The <B>-width</B>, <B>-height</B>,
<B>-reqwidth</B>, and <B>-reqheight</B> options, take a list of one, two, or three values.
We can take a previous example and instead preventing resizing, bound the
size of the scrollbars between two values. <BR>
<CODE>table . \<BR>
    .title   0,0 -cspan 3 \<BR>
    .canvas  1,1 -fill both \<BR>
    .vscroll 1,2 -fill y \<BR>
    .hscroll 2,1 -fill x<BR>
<P>
# Bound the scrollbars between 1/8 and 1/2 inch<BR>
table configure . c2 -width { 0.125 0.5 }<BR>
table configure . r2 -height { 0.125 0.5 }<BR>
table configure . vscroll .hscroll -fill both<BR>
</CODE><P>The scrollbars will get no smaller than 1/8 of an inch, or bigger than
1/2 inch.  The initial size will be their requested size, so long as it
is within the specified bounds. <P>
How the elements of the list are interpreted
is dependent upon the number of elements in the list.   <blockquote>
<DL>

<DT>{<I></I>} </DT>
<DD>Empty list. No
bounds are set. The default sizing is performed. </DD>

<DT>{<I> x </I>}  </DT>
<DD>Fixes the size to
<I>x</I>.  The window or partition cannot grow or shrink. </DD>

<DT>{<I> min max </I>} </DT>
<DD>Sets up minimum
and maximum limits for the size of the window or partition.  The window
or partition can be reduced less than <I>min</I>, nor can it be stretched beyond
<I>max</I>. </DD>

<DT>{<I> min max nom </I>} </DT>
<DD>Specifies minimum and maximum size limits, but also
specifies a nominal size <I>nom</I>.  This overrides the calculated size of the
window or partition. </DD>
</DL>

<H2><A NAME="sect11" HREF="#toc11">Miscellaneous</A></H2>
Another feature is that you can put two
widgets in the same cell of the table.  This is useful when you want to
add decorations around a widget. <BR>
<CODE>frame .frame -bd 1 -relief sunken<BR>
button .quit -text "Quit"<BR>
<P>
# Put both the frame and the button in the same cell.<BR>
table . \<BR>
    .quit  1,0 -padx 2 -pady 2 \<BR>
    .frame 1,0 -fill both<BR>

<H2><A NAME="sect12" HREF="#toc12"></CODE><P>Limitations</A></H2>
A long standing bug in Tk (circa 1993), there is no way to detect
if a window is already a container of a different geometry manager. This
is usually done by accident, such as the following where all three widgets
are arranged in the same container ".", but using different geometry managers.
<BR>
<CODE>    table .f1<BR>
<tt>&#32;</tt>&nbsp;<tt>&#32;</tt>&nbsp;...<BR>
    pack .f2<BR>
<tt>&#32;</tt>&nbsp;<tt>&#32;</tt>&nbsp;...<BR>
    grid .f3<BR>
</CODE><P>This leads to bizarre window resizing, as each geometry manager applies
its own brand of layout policies.  When the container is a top level window
(such as "."), your window manager may become locked as it responds to the
never-ending stream of resize requests.
