The Matrix Table is a short, stone table that holds bright, glowing Crystals. The crystals control various elements of the Land of the Lost. Almost every Pylon contains a Matrix Table, which controls that pylon's function. Enik's cave also contains a Matrix Table, which he experiments on.
The Tables can control the weather, sun, day, night, time, and can open doorways to another dimension when the correct sequence of colors are pressed.
