How do I load the URL into the other empty table column of id colOne? Right now if you click on the link, it will open the URL as a separate page. (I don't want to use an iFrame because it is notoriously fickle in Android devices.) Or can it be loaded on top of the page in some way?

Code:
<!DOCTYPE html>
<html>
<head>
<title>FROM: http://forums.digitalpoint.com/showthread.php?t=1110096</title>
<script>
function load(url)
{
window.open(url,'_blank');
}
</script>

<style type="text/css">
table { width: 800px; border: 3px dotted #aaa; }
#colOne, #colTwo { width:50%; }
</style>

</head>

<body>

<table>
<tr>
<td id="colOne">

</td>
<td id="colTwo">
<a href=#  onClick="load('listsub.html'); return false;">Show Menu</a>
</td>
</tr>
</table>

</body>
</html>
