it looks like you had a table already inside the main editable region:
<table width="90%">
<tr>
<td><p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p></td>
</tr>
</table>
data assist will not replace what is inside the editable region, it will only add to the editable region. It added the Data Assist form after the table that was already there.
