Hi,
I think I see your problem. First remove un-nessessary spaces, second you have no <TR></TR>'s and third the closing </TD> need to go directly after the last bit of table data, it can't go on the next line without showing a break or a space or gap.
Here is the new code for you to try:
<table width=100% border=0 cellpadding=0 cellspacing=0>
<tr>
<td align=left valign=top>
<table width=143 border=0 cellpadding=0 cellspacing=0>
<tr>
<td>(My TRs and TDs.. images and links..)</td>
</tr>
</table></td>
</tr>
---gap appears here---
<tr>
<td align=center valign=top>
<table width=100% border=0 cellpadding=0 cellspacing=0>
<tr>
<td>(Main Info)</td>
</tr>
</table></td>
</tr>
---another gap here---
<tr>
<td align=right valign=top>
<table width=143 border=0 cellpadding=0 cellspacing=0>
<tr>
<td>(More Links)</td>
</tr>
</table>
</td>
</tr>
</table>
Try that out and see if that works for you.
Hope this helps!
