          </s:iterator> 
     </tbody>
</table> 

Generated HTML(only for one row)

<tr>
  <td>ABW</td>
  <td>Aruba</td>
  <td>North America</td>
  <td>Unknown</td>
  <td>Beatrix</td>
  <td>Oranjestad</td>
  <td>Unedited</td>
  <td>Unedited</td>
  <td>
    <a href="/Struts2Login/editworld.action?Code=ABW">edit</a>
  </td>
</tr>
<tr> </tr>
