Move last 2 plugins in 1 row

[kernel]

I want to split the middle plugins column screen. I have 15 plugin spaces available but the last 2 - I want to be in same row splited like in clearly skin.

I think this is cut from the design template code where I should edit:

<?php

$inputsize = 35;

for($i = 5; $i < 15; $i++)
{
if($pluginpath[$i] != 'plugins/p1_empty/empty.php')
{ echo '

<tr>
<td width="100%" height="1" valign="top" class="padding_6"><table width="100%" border="0" cellpadding="0" cellspacing="0">
<tr>
<td width="100%" height="26" valign="top"><table width="100%" border="0" cellpadding="0" cellspacing="0">
<tr>
<td width="100%" height="26" valign="top" class="plugin_2_6"><table width="100%" border="0" cellpadding="0" cellspacing="0" class="plugin_2_7">
<tr>
<td width="100%" height="26" class="plugin_2_8" align="left" valign="middle"> ';
if(strlen($pluginname[$i]) > 0)
{
echo ' <div class="pluginname_1">' . $pluginname [$i] . '</div>
';
}
echo ' </td>
</tr>
</table>
</td>
</tr>
</table></td>
</tr>
<tr>
<td height="20" valign="top"><table width="100%" border="0" cellpadding="0" cellspacing="0">
<tr>
<td width="100%" height="20" valign="top"><table width="100%" border="0" cellpadding="0" cellspacing="0">
<tr>
<td width="100%" height="20" align="left" valign="top" class="content_2"> ';

include($pluginpath[$i]);

echo ' </td>
</tr>
</table>
</td>
</tr>
</table>
</td>
</tr>

</table></td>
</tr>

';
}
}

?>

Any idea how to do it?
