vuole dire che devi fare così :
codice:
<asp:TemplateColumn SortExpression="id" HeaderText="colonna template">
<ItemTemplate>
<table>
<tr>
<td><%# container.dataitem("id")%></td>
<td><%# container.dataitem("id2")%></td>
<td><%# container.dataitem("id3")%></td>
</tr>
<tr>
<td><%# container.dataitem("id32")%></td>
<td><%# container.dataitem("id232")%></td>
<td><%# container.dataitem("id3323")%></td>
</tr>
</table>
</ItemTemplate>
</asp:TemplateColumn>
