Sorry, for the subject... I'm just trying to make a similar table just like the ones here in this very forum. You have this orange header and under it the listings of the threads. The header has NO white space between but the lists have. What's the trick?

The problem is: each TD must have the same width as the TD below, so creating a new table won't be a solution and the code of this forum shows that it is not done so. They have a bgcolor defined in the TR of the orange header, but this doesn't seem to work at my site. THough I use the same browser..
