// TGTableLayout //
// //
// A LayoutManager which places child frames in a table. This uses //
// TGTableLayoutHints (not TGLayoutHints). See TGTableLayoutHints //
// for how to use these. This manager works like TGMatrixLayout with //
// the addition that: //
// - Child frames can span more than one column/row. //
// - Child frames can resize with the frame. //
// - Column and row sizes are not fixed nor (optionally) homogeneous. //
// - The number of columns and rows must be fully specified. //
