okay, I need some help with integrating the forums into my site, html-

I am trying to integrate my forums into my website by placing a header and footer around them -- the header and footer both contain tables.

In regular pages, the tables appear as I want them. However, when put into main.tpl, and then viewed in a forum page, the tables have a lot more space in them.

I want those tables to not have space in them, but for the forum to stay looking like it is, just with my header/footer tables. I've tried to define new table, td, and tr classes, setting padding, border, and border-spacing all to 0px, but still the extra spacing continues.

Can you help?
