+/**
+ A table with row selection capabilities.
+ 
+ This class implements a simple table with the ability to select
+ rows.  This widget is similar to an Fl_Browser with columns.  Most
+ methods of importance will be found in the Fl_Table widget, such
+ as Fl_Table::rows() and Fl_Table::cols().
+ 
+ To be useful it must be subclassed and at minimum the draw_cell()
+ method must be overridden to provide the content of the cells. This widget
+ does \em not manage the cell's data content; it is up to the parent
+ class's draw_cell() method override to provide this.
+ 
+ Events on the cells and/or headings generate callbacks when they are 
+ clicked by the user.  You control when events are generated based on
+ the values you supply for Fl_Table::when().
