I think this will work:
<script>
function ReloadTable()
{
document.getElementById('tableframe').location.href="tableURL.html";
setTimeout("ReloadTable()",5000);
};
</script>
<body onLoad="ReloadFrame();">
<iframe src="tableURL.html" name="tableframe" id="tableframe" style="border-width: 0px; border-style: none; "></iframe>
It will refresh the table every 5 seconds.
