First of all, I've been searching for an answer in Google and forums, but didn't find, sorry if it has been asked before and if you can link me to an answer it would be great.
Here's my problem: I have a web calculator made of a table with buttons inside. Here's a link. If you open it with IE it will be all messed up, so don't. I'll work on it later. On FF the rowspaned buttons do not stretch up and down to cover the hole cell, on Chrome it looks as intended. How do I make it look good on FF too? thx in advance to responders.
