I have tried that table creator you posted, and not only does it generate non-standards-complaint XHTML, but you'll notice between lines 22 - 31 (I put a comment there so you can see it) that a problem exists. I modified the code only by adding tabs (and the comment) to investigate the tag nesting (the issue you describe is usually caused by improper nesting).

<table width="466" cellpadding="0" cellspacing="0" border="0">
<tr>
	<td colspan="3">
		<img src="images/case/top.jpg" width="466" height="35" />
	</td>
</tr>
<tr>
	<td width="38">
		<img src="images/case/left.jpg" width="38" height="317" />
	</td>
	<td width="390" height="317" background="images/case/center.jpg" align="center">
		<table width="390" height="317" border="0">
		<tr>
			<td width="45" ></td>
			<td  align="center"></td>
			<td width="50" ></td>
		</tr>
		<tr>
			<td align="center"></td>
			<td  align="center">
				<table>
				<!-- nesting problems start here -->
				<tr>
					<td height="14" width="53">
						<td height="14" width="53">
							<td background="images/ribbons/commander1st.gif" align="center" height="14" width="53">
							</td>
							<td background="images/ribbons/commander2nd.gif" align="center" height="14" width="53">
							</td>
				</tr>
				<!-- / nesting problems end here -->
				<tr>
					<td background="images/ribbons/soldiers.gif"align="center"  height="14" width="53">
					</td>
					<td background="images/ribbons/silverStar.gif" height="14" align="center" width="53">
					</td>
					<td background="images/ribbons/goodConduct.gif" height="14" align="center" width="53">
					</td>
					<td background="images/ribbons/tra.gif" height="14" width="53" >
					</td>
				</tr>
				<tr>
				</tr>
				</table>
			</td>
			<td> </td>
		</tr>
		<tr>
			<td width="45" ></td>
			<td align="center">
				<img src="images/badges/sharpshooter.jpg">
			</td>
			<td width="50" ></td>
		</tr>
		</table>
	</td>
	<td width="38">
		<img src="images/case/right.jpg" width="38" height="317" />
	</td>
</tr>
<tr>
	<td colspan="3">
		<img src="images/case/bottom.jpg" width="466" height="38" />
	</td>
</tr>
</table>

As you can see, this is an issue with the tool you mentioned and not with this mod.
