Extreme frustration. WTF. Table Widths!! Options

Ok... So what I want to do is have all the tables on the LEFT column be the SAME WIDTH, and all the tables on the RIGHT column be the SAME WIDTH. I managed to get pretty close by using

table table td.text table {width: 100%;}

HOWEVER, in FIREFOX the right column tables are stretched out a bit, but in EXPLORER it looks fine. Why does Firefox have to stretch the stupid tables out? Is there any way to fix this? I tried doing width: 435px but it just screws everything up. I've seen this done before but I don't understand why it's so hard to get this to work.

Ugh I'm beginning to get very annoyed with Firefox..
