or even this may work, i tested it looks fine for me, but you may have to play again with width and heights:
<table width ="10%" border="1"align="left">
<tr><td>data 1</td></tr>
<tr><td>data 2</td></tr>
<tr><td>data 3</td></tr>
</table>
<table width ="90%" border="1" align="right">
<tr><td>data 1 in the second table</td></tr>
<tr><td>data 2 in the second table</td></tr>
<tr><td>data 3 in the second table</td></tr>
<tr><td>data 4 in the second table</td></tr>
<tr><td>data 5 in the second table</td></tr>
</table>
ik
looking at your site it really only has 3 columns so you could make 3 tables for this:
<table width ="10%" border="1"align="left">
<tr><td>data 1</td></tr>
<tr><td>data 2</td></tr>
<tr><td>data 3</td></tr>
</table>
<table width ="10%" border="1"align="right">
<tr><td>data 1 in the 3rd table</td></tr>
<tr><td>data 2 in the 3rd table</td></tr>
<tr><td>data 3 in the 3rd table</td></tr>
</table>
<table width ="80%" border="1" align="center">
<tr><td>data 1 in the second table</td></tr>
<tr><td>data 2 in the second table</td></tr>
<tr><td>data 3 in the second table</td></tr>
<tr><td>data 4 in the second table</td></tr>
<tr><td>data 5 in the second table</td></tr>
</table>
notice how all the widths = 100%
