title: Why is Firefox missing the border on some HTML tables
body: <p>I am using Firefox 3.5.7 and I have the same CSS used in multiple HTML tables, but there are some examples where parts of the borders are not shown.  </p>
  
  <p>What makes no sense to me is that the same CSS on the same page for another HTML table works fine. Also, the same page in Internet Explorer looks fine from a border point of view.  </p>
  
  <p>Here is an image with an example, as you can see in this case the bottom of the first table is missing a border.</p>

  <p>Does anyone have a clue why this would happen here?</p>
