error tables align in firefox

since version 2.5 FCKeditor instead of aling="center" use style="text-align:center". it is good to use css but there is some compatibility problems.
try this code in FF and in IE and you will see that in FF table ignore text-align.

<div style="text-align:center">
<table>
    <tbody>
        <tr>
            <td>reerergrger</td>
        </tr>
    </tbody>
</table>
</div> 

if instead of style="text-align:center" use align="center" - all works fine in all browsers.
May be it'll be beter to use align="center" for element align in FCKedotor??
