That should do it, assuming you are formatting these after the fact ;)
Or assuming you aren't, you could try...
<!-- Display center blocks if any -->
<{if $xoops_showcblock == 1}>
<table width="100%" border="0" cellspacing="0" cellpadding="0">
<tr>
<td>
<!-- Start center-left blocks loop -->
<{foreach item=block from=$xoops_clblocks}>
<{include file="shadowman/theme_blockcenter_l.html"}>
<{/foreach}>
<!-- End center-left blocks loop -->
</td>
<td>
<!-- Start center-right blocks loop -->
<{foreach item=block from=$xoops_crblocks}>
<{include file="shadowman/theme_blockcenter_r.html"}>
<{/foreach}>
<!-- End center-right blocks loop -->
</td>
</tr>
</table>
<!-- Start center-center blocks loop -->
<{foreach item=block from=$xoops_ccblocks}>
<{include file="shadowman/theme_blockcenter_c.html"}>
<{/foreach}>
<!-- End center-center blocks loop -->
<{/if}>
<!-- End display center blocks -->
Hope this helps :)
