Borders

What is it with Reporting Services and borders? I am creating a table to put my data into, but whenever I add borders and upload the report file and view it on my website, the borders more often than not have gaps between them, or are double the thickness they should be, or are not straight lines. It means that I am ending up not using borders in my tables. Anybody know how to do something about this?

Set the background of the table to Transparent instead of White.

Or make sure the borders don't overlap. (Like setting only the right border on a thickness of 1, instead of both left and right (except for the first one)
