I suggest you use CSS instead, seems like you're going to repeat those lines later on. But to answer your question:
<html>
<head>
<style type="text/css">
td.randname {
padding-left: 5px;
padding-bottom:3px;
font-size:35px;
}
</style>
</head>
<body>
<table>
<tr>
<td class="randname"> <b>Datum:</b><br/>
November 2010 </td></tr>
</table>
</body>
</html>
