How can I easily center a RadioButtonList? It used to be straightforward, but for some reason the below HTML is not working. Can you spot what's missing?
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<table style="width:100%">
<tr>
<td style="text-align: center">
<asp:RadioButtonList ID="radUserType" runat="server"
RepeatDirection="Horizontal">
</asp:RadioButtonList>
</td>
</tr>
</table>
</div>
</form>
</body>
</html>
