Try the below code. I think it will help you.
<table width="100%">
<tr>
<td class="contentDetails">
<th align="left"> <h3><strong>text align right</strong></h3></th>
<th align="center"> <h3><strong>text align center</strong></h3></th>
<th align="right"> <h3><strong>text align left</strong></h3></th>
</td>
</tr>
</table>
