Top/Bottom Borders Per Category as seen on PixelJunction.com

[Boeman]

I have my categories as seperate entities which includes their forum headers ("Forum", "No. of Views", "Moderators" etc) along with the actual forum data following underneath.

I have added a border by inserting an additional <tr> tag to stylize the forum categories to the top but the bottom remains elusive. If I try inserting the last <Tr> code into formbit_1 no post template then the border appears underneath every category instead of underneath the listed subforms.

Look at pixeljunction.com and their forum home to get an idea what I'm trying to do. When viewing their html the border tables ares located where they have commented at "begin border code".

Any help here would be greatly appreciated. Thanks!
