Is it possible to get data out of table cells and put it into a Javascript variable? If so, how?

Sure, it is possible to get data out of table cells and put it into a Javascript variable. The best way is to put an id on the table, and get it by id.

<table id="getMe">
    <tr><td>[some data]</td></tr>
</table>

var v, theTable;
theTable = document.getElementById("getMe");
v = theTable.rows[0].cells[0].value;

I hope that’s clear.
