// "$Id$"
//
// Simple example of using Fl_Table - Greg Ercolano 11/29/2010
//
// Demonstrates the simplest use of Fl_Table possible.
// Display a 10x10 array of integers with row/col headers.
// No interaction; simple display of data only.
// See other examples for more complex interactions with the table.
