Cant get this box to work :(

[Xencored]

Could someone help me out with some code for a Adsense Box

So i have the Same colour bar as my Skins

<table border="1" bordercolor="" width="" bgcolor="">
<tr>
<td> AD CODE </td>
</tr>
</table>

Can this be done so i dont have to add a diff one for every skin

Like the same box in this image for the ad-code
Thanks

<table border="1" bordercolor="" width="" bgcolor="">
<tr>
<td class="tcat"> AD CODE </td>
</tr>
</table>
