Attached is code that sorts a table of data. Read inline comments.
I suppose for your application you would pass it the <tbody> tag ID for that inner table.
Summary:
Click on table heading to sort by that column. Here's how I set it up. parameters are explained in the code listing.
<html>
<head>
<script type='text/javascript/ src='filepath/table_sort.js'></script>
</head>
<body>
<table>
<th onclick="return sortTable('systemList', 0, false); ">This column</th>
<th onclick="return sortTable('systemList', 1, false); ">That column</th>
<th onclick="return sortTable('systemList', 2, false); ">'nuther column</th>
<tbody id='systemList'>
<!-- table data rows here -->
</tbody>
</table>
</body>
</html>
