Display In 2-Column Table
The below can be applied to MT, EE, etc, and will display the content in a 2 column table. The EE tags below are just an example, it will work equally well if you replace it with MT, Wordpress, etc, tags.
<? $set_table="0"; ?>
<table cellpadding="5" border="0">
{exp:gallery:categories gallery="{gallery_name}"}
<?
$fs_table = $set_table +1;
if ($set_table == "1") {echo"<tr>";} ?>
Insert other tags here.
<? if ($set_table == "2") {echo"</tr>"; $set_table="0";} ?>
{/exp:gallery:categories}
</table>
