<style type="text/css">

    table {width:600px;table-layout:fixed;}

    td {white-space:nowrap;overflow:hidden;word-break:keep-all;text-overflow:ellipsis}

</style>

<table border=1 >

    <tr>

        <td width="30%">dd</td>

        <td>ddddddddddddddddddddddddddddddfsljdflsajufiajklsjadflkjsalkfdjdsklajdflksajflksajfdlkdsjdflksjfjldskajdflksajflskajf</td>

        <td width="30%">dd</td>
