"div" tag can not be used above "tr" tag. Instead you can use "tbody" tag to do your work. If you are planning to give id attribute to div tag and doing some processing, same purpose you can achieve through "tbody" tag. Div and Table are both block level elements. so they can not be nested.
For further information visit this page
For example:
<table>
<tbody class="green">
<tr>
<td>Data</td>
</tr>
</tbody>
<tbody class="blue">
<tr>
<td>Data</td>
</tr>
</tbody>
</table>
secondly, you can put "div" tag inside "td" tag.
<table>
<tr>
<td>
<div></div>
</td>
</tr>
</table>
