UBB.threads PHP Forum Software Community Forums Resources and Customizing How Do I? Different table styles

I'd like to have different table borders for some tables than others but I can't seem to figure it out.

For example, I'd like to have one border style for the forum list, topic list, and message list, and another border style for everything else. It doesn't seem to matter what I do, anything I change makes the changes for all the tables.

I even looked at some of the forum styles people have posted on this site and UBBDev, but it looks like people are all using the same border style for all tables. Is this because it can't be done easily?

Any help would be greatly appreciated.

Thanks.

I'm not entirely sure how this would be done; all borders use the table wrappers, and only one can be defined per style...
