Vorrei che il td che contiene il div con id vertical fosse il 100% in altezza ma viene ignorato dai browser come posso fare?
codice:

    </head>
    <body>
        <table cellpadding="0" cellspacing="0">
            <tr>
                <td>
                    <div id="topleft">
                    </div>
                </td>
                <td id="center">
                </td>
            </tr>
            <tr>
                <td>
                    <div id="vertical">
                    </div>
                </td>
                <td id"center_bottom">
                </td>
            </tr>
        </table>
    </body>
</html>
