This may give you an idea:
[code:1:3917171e94]<table width="100%" height="100%" border="0" cellspacing="0" cellpadding="0">
<tr>
<td>
<table width="100%" height="100%" border="0" cellspacing="0" cellpadding="0">
<tr>
<td>[HEADER]</td>
</tr>
<tr>
<td height="100%"> </td>
</tr>
<tr>
<td>[FOOTER]</td>
</tr>
</table>
</td>
</tr>
</table>[/code:1:3917171e94]
[FOOTER] always appear at the bottom of the page with this structure.
Edit: I've also added [HEADER] to the top.
