The XbaeMatrix is a Motif-based widget which displays a grid of cells in the same manner as a spreadsheet. The cell array is scrollable, editable, and otherwise reasonably configurable in appearance. Each cell usually displays text, but pixmaps can also be displayed (not editeable). The XbaeMatrix looks to some extent like a grid of XmTextField widgets, but is actually implemented with a single XmTextField. This means a big performance improvement due to less overhead.
