Nice looking HTML tables usually require a style sheet or scaled dummy images or are highly browser dependant. The problem is how to render a colored table cell that is only 2 pixels high. Here is a table, that should render nicely under Internet-Explorer, Opera, Mozilla, Konqueror, Galeon and Netscape. We use
  <td height=2 bgcolor="#777777"><table border=0 cellpadding=0 cellspacing=0><tr><td></td></td></table></td>
A simpler construct would be
  <td height=2 bgcolor="#777777"></td>
But then Netscape-4.8 would render it transparent. First as an image that shows what is expected, below the pure HTML construct.
