Well I would use CSS and also a DIV instead of a table, but if you must use a table try this out...
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>Untitled Document</title>
<style type="text/css">
<!--
#noot {
overflow: scroll;
background-color: #CCCCCC;
height: 270px;
width: 200px;
}
-->
</style>
</head>
<body>
<table id="noot">
<tr>
<td> </td>
</tr>
</table>
</body>
</html>
as you can see the table is givin a id ("noot") and is controld via css (#noot {
overflow: scroll;
background-color: #CCCCCC;
height: 270px;
width: 200px;
}).
