Sure:

<table>
    <thead>
        <th>
            <td>Name</td>
            <td>Age</td>
       </th>
   </thead>
   <tbody n:data="data" n:render="sequence">
      <tr n:pattern="item" n:render="mapping">
          <td> <n:slot name="name" /> </td>
          <td> <n:slot name="age" />  </td>
      </tr>
   </tbody>
</table>

If you really want a pattern then write a new mapping that gathers some known
patterns from the enclosed html and fills the corresponding slots.
