Looks like they created a grid with a Secondary Header and the bottom is 1 column at 100%. Then flatten the grid. Then edit to put three divs, each 33%, into the Secondary Header.

Should end up with something like:

<div id="doc3">
    <div id="hd" class="yui-gb">
        <div class="yui-u first">
            <ul class="list_no_decoration widget_list" id="widgetlist_column2">$column[2]</ul>
        </div>
        <div class="yui-u">
            <ul class="list_no_decoration widget_list" id="widgetlist_column3">$column[3]</ul>
        </div>
        <div class="yui-u">
            <ul class="list_no_decoration widget_list" id="widgetlist_column4">$column[4]</ul>
        </div>
    </div>
    <div id="bd">
        <div class="yui-u yui-panel">
            <ul class="list_no_decoration widget_list" id="widgetlist_column1">$column[1]</ul>
        </div>
    </div>
</div>
