Here's te code for 4.1.2. Works well.
Code:
{capture name=dialog}
{assign var="tmp" value="0"}
{section name=mid loop=$manufacturers}
{if $manufacturers[mid].manufacturerid}{assign var="tmp" value="1"}{/if}
{/section}
{section name=mid loop=$manufacturers}
{ if %mid.first% }
<table width="100%" border="0" align="center" cellpadding="5" cellspacing="0">
{/if}
{ if %mid.index% is div by 3}
<tr>
{/if}
<td align="center" valign="middle">
<table bgcolor="#FFFFFF" cellspacing="0" cellpadding="0" border="0"><tr><td height="70">
[img]image.php?id={$manufacturers[mid].manufacturerid}&type=M[/img]</td></tr>
<tr><td align="center" valign="middle">
<font class="ItemsList">{$manufacturers[mid].manufacturer}</font></td></tr></table>
</td>
{ if %mid.last% }
</tr>
</table>
{/if}
{/section}
{/capture}
{include file="dialog.tpl" title=$lng.lbl_manufacturers content=$smarty.capture.dialog extra='width="100%"'}
It is in three column, if you want more, just change
Code:
{ if %mid.index% is div by 3}
