Don't putting the alignment in the table tag. Leave the table tag without alignment, and then align the table as you would align text.
Here is a link with some good information for you...
Code:
<p align="left">
<table border="1px" width="500">
<tr>
<td align="left" width="250"> Cell One</td>
<td align="left" width="250"> Cell Two</td>
</tr>
<tr>
<td align="left" width="250"> Cell Three</td>
<td align="left" width="250"> Cell Four</td>
</tr>
</table>
