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?

<!DOCTYPE html>
function load(url)

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



<td id="colOne">

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