Footer (aka bottom?) selector color and border

How do I set the footer selector color and top margin? In the example spreadsheet at: http://www.facilities.gatech.edu/active_widgets/spreadsheet.html

I'd like the selector ("Combined") to have a lightgray background with a 1px solid black top margin, to match the rest of the footer.

Thanks,

I would suggest making the selector transparent and set color and border on the footer row itself -

.aw-footer-0 .aw-row-selector {
    background: none;
    border: none;
}

.aw-footer-0 {
    border-top: 1px solid black;
    background: lightgrey;
}
