 * SECTION:clutter-table-layout
 * @title: ClutterTableLayout
 * @short_description: A layout manager arranging children in rows
 *   and columns
 *
 * The #ClutterTableLayout is a #ClutterLayoutManager implementing the
 * following layout policy:
 *
 *   - children are arranged in a table
 *   - each child specifies the specific row and column
 *   cell to appear;
 *   - a child can also set a span, and this way, take
 *   more than one cell both horizontally and vertically;
 *   - each child will be allocated to its natural
 *   size or, if set to expand, the available size;
 *   - if a child is set to fill on either (or both)
 *   axis, its allocation will match all the available size; the
 *   fill layout property only makes sense if the expand property is
 *   also set;
 *   - if a child is set to expand but not to fill then
 *   it is possible to control the alignment using the horizontal and
 *   vertical alignment layout properties.
 *
 * It is possible to control the spacing between children of a
 * #ClutterTableLayout by using clutter_table_layout_set_row_spacing()
 * and clutter_table_layout_set_column_spacing().
 *
 * In order to set the layout properties when packing an actor inside a
 * #ClutterTableLayout you should use the clutter_table_layout_pack()
 * function.
 *
 * A #ClutterTableLayout can use animations to transition between different
 * values of the layout management properties; the easing mode and duration
 * used for the animations are controlled by the
 * #ClutterTableLayout:easing-mode and #ClutterTableLayout:easing-duration
 * properties and their accessor functions.
 *
 * #ClutterTableLayout is available since Clutter 1.4
 *
 * Since Clutter 1.18 it's recommended to use #ClutterGridLayout instead
 * of #ClutterTableLayout; the former supports right-to-left text direction,
 * as well as using the alignment and expansion flags on #ClutterActor.
