GtkTable::resize
void resize(int rows, int columns);
This method is used internally to resize the table and rearrange the
child widgets accordingly following a new child's attachment to a
non-homogeneous table, or a change in the size of the largest child
in a homogeneous table.
It can be used to redraw a homogeneous table with a new number of
rows and columns, all of which will have the same size as existing
rows and columns. It has no external use in a non-homogeneous table.
