Will never forget having to create collections of tl.gif, tr.gif, bl.gif etc. images for those 3x3 tables, not to mention the 1x1.gif the article mentioned that was needed for the left/right cell backgrounds to show since browsers at the time didn't render background images of empty cells. Good times.
