/**
* SECTION:gtktable
* @Short_description: Pack widgets in regular patterns
* @Title: GtkTable
* @See_also: #GtkGrid
*
* 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.
*
* Tables are created with a call to gtk_table_new(), the size of which can
* later be changed with gtk_table_resize().
*
* Widgets can be added to a table using gtk_table_attach() or the more
* convenient (but slightly less flexible) gtk_table_attach_defaults().
*
* To alter the space next to a specific row, use gtk_table_set_row_spacing(),
* and for a column, gtk_table_set_col_spacing().
* The gaps between all rows or columns can be changed by
* calling gtk_table_set_row_spacings() or gtk_table_set_col_spacings()
* respectively. Note that spacing is added between the
* children, while padding added by gtk_table_attach() is added on
* either side of the widget it belongs to.
*
* 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.
*
* > #GtkTable has been deprecated. Use #GtkGrid instead. It provides the same
* > capabilities as GtkTable for arranging widgets in a rectangular grid, but
* > does support height-for-width geometry management.
