datatables wants format:

    <table>      <thead>       <tr>        <td>col 1 head</td>        <td>col 2 head</td>        <td>col 3 head</td>       </tr>     </thead>     <tbody>      <tr>       <td>col 1 body</td>       <td>col 2 body</td>       <td>col 3 body</td>      </tr>     </tbody>    </table>
