Custom Drop Down Menu Help

[Chase]

Hey gang I need some help trying to achieve a drop down menu like the attached picture looks like. It's a different look but would really suit my needs. Can you guys give me a hand here? I've tried adding a simple table code inside but that didn't work.

Here is the plugin code I am working with.

PHP Code:

$template_hook['navbar_after_calendar'] .= ' 
<li class="popupmenu"> 
<a href="javascript://" class="popupctrl">Links</a> 
<ul class="popupbody popuphover"> 
<li><a href="http://www.url.com" target="blank">Link</a></li> 
<li><a href="http://www.url.com" target="blank">Link</a></li>
<li><a href="http://www.url.com" target="blank">Link</a></li>
<li><a href="http://www.url.com" target="blank">Link</a></li>
<li><a href="http://www.url.com" target="blank">Link</a></li>
<table>
    <tr>
        <li><td>Table Cell</td></li>
        <li><td>Table Cell</td></li>
    </tr>
    <tr>
        <li><td>Table Cell</td></li>
        <li><td>Table Cell</td></li>
    </tr>
    
</table>
</ul> '; 


Think you guys can give me a hand here?
