Question about formatting widget output

By Dan

I would like to output information in a widget using an html table except it doesn't come out quite the way I expected. The beginning of it looks like this:

<div class="contentWrapper">
<table>
<tr><th>Activity</th><th align="right">Score</th></tr>

Inserting     border="1"    in the table tag doesn't change anything.  Can someone advise me where to look?  I'm a newb on css, but I'm assuming some css file overrides the tag definitions.
