table within table

csharpcoder

I have a requirement that wants a table inside a table to show details such as

<table>
<tr><td>comments</td><td>author</td><td>count</td></tr>
<tr><td>
           <table><tr><td>replies></td><td>author</td><td>date submitted</td></tr></table>
       </td>
</tr>
</table>

when i run my code, i'm getting an error message and points me to the http://www.datatables.net/manual/tech-notes/4 page, can we not have a table within table like I need? (I'm using the group feature for the datatable)
