tbody width not automatically extending to width of table

Take a look at this example here:

http://denise.brixwork.com/showlisting/1/8297-Valley-Drive-Alpine-Meadows-Whistler-denise-brown-real-estate

And the red tables under "Specifications" is not becoming the full width of the containing it - when inspecting on Firebug, the div is not 220 pixels, but rather, just over a 100 pixels based on the content width.

<div class="grid_4 alpha">
    <table width="100%" class="grid_4 alpha omega">
            <tr class="specrow">
            <td class="specname">type:</td>
            <td class="specvalue">House</td>
        </tr>
        <tr class="specrow">
            <td class="specname">year:</td>
            <td class="specvalue">1986</td>
        </tr>
    </table>
</div>

The CSS code looks like this:

#listing_specs table {
    width: 100%;
}

#listing_specs table tbody {
    display: table-row-group;
    width: 100%;
}

.specrow {
    margin:2px 0px;
    border-bottom:1px dotted #dadada;
    color: #fff;
    width: 100%;
    background-color: #A92229;
}

.specrow:hover {
    background-color:#fff;
    color:#333;
}

.specname{
    font-weight: 600;
    padding:2px 2px 2px 5px;
    width: 50%;
    white-space: nowrap;
}

.specvalue {
    font-weight:normal;
    padding:2px 5px 2px 5px;
    text-align:left;
    width: 50%;
}

I know there is a generic CSS resetter, and I think that's what's causing the problem. Unfortunately I can't go and just remove the reference to it because multiple sites refer to it from the same location at this moment, and I can't just make that change without careful review. So I need a way to override it on the stylesheet itself. The reset CSS being called is:

<link rel="stylesheet" type="text/css" media="all" href="http://demo.brixwork.com/master/css/reset.css" />

you should just add

display: table;

under this selector:

#listing_specs table { }
