Hopefully this is what you are looking for (please note that I am not using this particular item):

Code
 <?php
if (!defined('UBB_MAIN_PROGRAM')) define('UBB_MAIN_PROGRAM',1);
$style_side="";$tbopen="";$tbclose="";
echo "<table width=\"100%\">";
include("/services/webpages/p/a/parkcitiestactical.com/public/ubbthreads/languages/english/portal_islands.php");
include("/services/webpages/p/a/parkcitiestactical.com/public/ubbthreads/languages/english/generic.php");
include("/services/webpages/p/a/parkcitiestactical.com/public/ubbthreads/cache/portal_box_1.php");
echo "</table>";
?>

Inserting the code above will insert the following HTML into it's place. As you can see there are 2 CSS classes you'll want to define for the included HTML, those being tdheader and alt-1. You can modify the properties of the table itself in the code above.:

<table width="100%">
<tr>
<td class="tdheader">
Portal Box 1
</td>
</tr>
<tr>
<td class="alt-1">

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