Or...
var myTDs = new Array();
$A($("main").childNodes).each(function(tr)
{
$A(tr.childNodes).each(function(td)
{
myTDs.push(td);
});
});

Subject: Re: [Rails-spinoffs] manipulate <td>'s and their content by
grabbingtheir classNames
<p align=\"left\"><b><font face=\"Arial\" size=\"2\">GFI MailSecurity's
HTML threat engine found HTML scripts in this email and has disabled

pointer to the selected index, rather than traversing through the dom
each time you change the active cell.
Something along :
<Xcript type="text/javascript"><!--
MyController = {
selected : null,
select : function(elm) {
if (this.selected) {
this.selected.className = "";
}
this.selected = elm;
elm.className = "selected";
}
}
--></Xcript>
<table>
<tr>
<td onclick="MyController.select(this)">foo</td>
<tr>
<tr>
<td onclick="MyController.select(this)">bar</td>
<tr>
</table>
