Working with Javascript to display: table-cell in IE <= 7

The community has recently provided some great tools to let early versions of IE do what they never intended to do. Like multi-sector css selectors. Unfortunately, I could not find a java script that I can load conditionally in IE lte 7, which converts multi-column layouts that use display: table-cell.

Does anyone know about such a script?

<div id="sidebar">
   <ul id="main_nav">
      <li><a href="about_us.php">ABOUT US</a></li>
   </ul>
</div> <!--end of sidebar-->

<div id="content">
   <div id="main_content">
     <h1>Header</h1>
     <p>Page Content</p>
   </div> <!--end of main_content-->

   <div class="aside_info">
      <h2>Side Info</h2>         
   </div>
</div> <!--end of content-->

There are 3 columns #side_bar and #content - columns, and inside #content there are #main_content and #aside_info. This works great to create a three-column layout on a page that has a #aside_info div but has two columns differently.

if anyone knows a script that converts this to tables for reverse browsers, I would appreciate it.

, jQuery:

$('<table><tr><td></td><td></td><td></td></tr></table>')
    .find('td')
        .eq(0)
            .append( $('#sidebar') )
            .end()
        .eq(1)
            .append( $('#main_content') )
            .end()
        .eq(2)
            .append( $('.aside_info') )
            .end()
        .end()
    .appendTo( $('#content') );
