- * 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.
