You could put the two codes next to each other, and using div tags, CSS float. You could float each left and right ? Thanks
<div style="float:left">Ad1 </div> <div style="float:right">Ad2</div> you have to manage contents between these divisions.
<table width="200/400/As you want" border="0"> <tr> <td>Ads 1 </td> <td>Ads 2 </td> </tr> </table> Or <div style="float:left">Ads 1 </div> <div style="float:right">Ads 2</div>
