Use a single table with two cells. Either two columns and one row or two rows and one column. Depends on if you want them butted up against each other vertically or horizontally.
Two Cells in a able on top of each other would look something like this:
<table width="100%" border="0" cellspacing="0" cellpadding="0">
<tr align="left" valign="bottom">
<td></td>
</tr>
<tr align="left" valign="top">
<td></td>
</tr>
</table>
And two cells next to each other would look something like this:
<table width="100%" border="0" cellspacing="0" cellpadding="0">
<tr>
<td align="right" valign="top"></td>
<td align="left" valign="top</td>
</tr>
</table>
Of course you will probably want to change the table width, but you get the idea.
Hope this helps!!!
