This GTK+ version 2.12.3. GTK+ is a multi-platform toolkit for creating graphical user interfaces.

<!-- ##### SECTION Title ##### -->
GtkTable

<!-- ##### SECTION Short_Description ##### -->
Pack widgets in regular patterns

<!-- ##### SECTION Long_Description ##### -->
<para>
The #GtkTable functions allow the programmer to arrange widgets in rows and
columns, making it easy to align many widgets next to each other,
horizontally and vertically.
</para>
<para>
Tables are created with a call to gtk_table_new(), the size of which can
later be changed with gtk_table_resize().
</para>
<para>
Widgets can be added to a table using gtk_table_attach() or the more
convenient (but slightly less flexible) gtk_table_attach_defaults().
</para>
<para>
To alter the space next to a specific row, use gtk_table_set_row_spacing(),
and for a column, gtk_table_set_col_spacing().</para>
<para>
The gaps between <emphasis>all</emphasis> rows or columns can be changed by calling
gtk_table_set_row_spacings() or gtk_table_set_col_spacings() respectively.
</para>
<para>
gtk_table_set_homogeneous(), can be used to set whether all cells in the
table will resize themselves to the size of the largest widget in the table.
</para>

<!-- ##### STRUCT GtkTable ##### -->
<para>
The <structname>GtkTable</structname> structure holds the data for the actual table itself. 

<structfield>children</structfield> is a #GList of all the widgets the table contains. <structfield>rows</structfield> and <structfield>columns</structfield> are pointers to #GtkTableRowCol structures, which contain the default spacing and expansion details for the #GtkTable's rows and columns, respectively.
</para>
<para>
<structfield>nrows</structfield> and <structfield>ncols</structfield> are 16bit integers storing the number of rows and columns the table has. 
</para>

<!-- ##### STRUCT GtkTableChild ##### -->
<para>
The <structfield>widget</structfield> field is a pointer to the widget that 
this %GtkTableChild structure is keeping track of.
The <structfield>left_attach</structfield>,
<structfield>right_attach</structfield>,
<structfield>top_attach</structfield>, and
<structfield>bottom_attach</structfield> fields specify the row and column
numbers which make up the invisible rectangle that the child widget is packed into.
</para>
<para>
<structfield>xpadding</structfield> and <structfield>ypadding</structfield>
specify the space between this widget and the surrounding table cells.

<!-- ##### FUNCTION gtk_table_new ##### -->
<para>
Used to create a new table widget. An initial size must be given by
specifying how many rows and columns the table should have, although
this can be changed later with gtk_table_resize().  @rows and @columns
must both be in the range 0 .. 65535.
</para>

@rows: The number of rows the new table should have.
@columns: The number of columns the new table should have.
@homogeneous: If set to %TRUE, all table cells are resized to the size of the cell
containing the largest widget.
@Returns: A pointer to the the newly created table widget.


<!-- ##### FUNCTION gtk_table_resize ##### -->
<para>
If you need to change a table's size <emphasis>after</emphasis> it has been created, this function allows you to do so.
</para>

@table: The #GtkTable you wish to change the size of.
@rows: The new number of rows.
@columns: The new number of columns.


<!-- ##### FUNCTION gtk_table_attach ##### -->
<para>
Adds a widget to a table. The number of 'cells' that a widget will occupy is
specified by @left_attach, @right_attach, @top_attach and @bottom_attach.
These each represent the leftmost, rightmost, uppermost and lowest column
and row numbers of the table. (Columns and rows are indexed from zero).
</para>

@table: The #GtkTable to add a new widget to.
@child: The widget to add.
@left_attach: the column number to attach the left side of a child widget to.
@right_attach: the column number to attach the right side of a child widget to.
@top_attach: the row number to attach the top of a child widget to.
@bottom_attach: the row number to attach the bottom of a child widget to.
@xoptions: Used to specify the properties of the child widget when the table is resized.
@yoptions: The same as xoptions, except this field determines behaviour of vertical resizing.
@xpadding: An integer value specifying the padding on the left and right of the widget being added to the table.
@ypadding: The amount of padding above and below the child widget.


<!-- ##### FUNCTION gtk_table_attach_defaults ##### -->
<para>
As there are many options associated with gtk_table_attach(), this convenience function provides the programmer with a means to add children to a table with identical padding and expansion options. The values used for the #GtkAttachOptions are <literal>GTK_EXPAND | GTK_FILL</literal>, and the padding is set to 0.
</para>

@table: The table to add a new child widget to.
@widget: The child widget to add.
@left_attach: The column number to attach the left side of the child widget to.
@right_attach: The column number to attach the right side of the child widget to.
@top_attach: The row number to attach the top of the child widget to.
@bottom_attach: The row number to attach the bottom of the child widget to.


<!-- ##### FUNCTION gtk_table_set_row_spacing ##### -->
<para>
Changes the space between a given table row and the subsequent row.
</para>

@table: a #GtkTable containing the row whose properties you wish to change.
@row: row number whose spacing will be changed.
@spacing: number of pixels that the spacing should take up.


<!-- ##### FUNCTION gtk_table_set_col_spacing ##### -->
<para>
Alters the amount of space between a given table column and the following 
column.
</para>

@table: a #GtkTable.
@column: the column whose spacing should be changed.
@spacing: number of pixels that the spacing should take up.


<!-- ##### FUNCTION gtk_table_set_row_spacings ##### -->
<para>
Sets the space between every row in @table equal to @spacing.
</para>

@table: a #GtkTable.
@spacing: the number of pixels of space to place between every row in the table.


<!-- ##### FUNCTION gtk_table_set_col_spacings ##### -->
<para>
Sets the space between every column in @table equal to @spacing.
</para>

@table: a #GtkTable.
@spacing: the number of pixels of space to place between every column in the table.


<!-- ##### FUNCTION gtk_table_set_homogeneous ##### -->
<para>
Changes the homogenous property of table cells, ie. whether all cells are an equal size or not.
</para>

@table: The #GtkTable you wish to set the homogeneous properties of.
@homogeneous: Set to %TRUE to ensure all table cells are the same size. Set
to %FALSE if this is not your desired behaviour.
