a form submit problem related to web browser

In my case, I wrote a page which include a table like
<table>
    <tr>
        <form_tag ....>
             <td>
                  ......
             </td>
when submit this form in Firefox, the params in RAILS controller
doesn't include the form's content, but it works with IE. I guess it's
a problem related to certain browser mechanism, but still dont know
how to solve it.

Put your form content in table cells like <td>, not <tr>.
