Decorating Zend_Captcha_Image in my table layout form ??

Question

I want to fit my captcha in my table based form , but buy simply adding Zend_Form_Element_Captcha , which uses its own decorator messes up my table based form layout. I hope there is some way so it gets like

    <tr>
<td></td>
<td><img src="343444.png"/></td>
</tr>
<tr>
<td>Write the above text</td>
<td><input type="text" name="foo[input]"></td>
</tr>
