I have a giant table in my website, www.MillionDollarAppSite.com. It started off as 33 squares (cells) x 31 squares, but then some squares were combined to make larger squares. Everything looked fine in Safari, Firefox, and Internet Explorer, but then today, when I combined four squares to make a larger square, the height of the bottom two squares changed. Now the site looks fine in Safari and Firefox, but it looks terrible in Internet Explorer. What can I do to fix this?
