Sorry, that's my fault. I could swear that's how I did it before, but I guess if you say "100%" it takes up as much space as it can even if the other cell has a pixel width. I'm going to look up how I did that...
Yeah, OK - the "100%" should go on the table tag, not the second td tag (I changed the code in the above post).
Sorry again.
actually that didn't work either. I tried that about 10 minutes in. If you are interested on exactly how i did this i can PM you a link to how i did it. I will be releasing it in a mod soon enough for people who are interested in doing something similar. IT allows people to add a side bar to any single page and even recreate an exact look alike of the link i posted in my first post if they wanted to. Either way its pretty nice
