Stretch a column

How can I stretch a column so that it fill the remaining space on the screen?
.active-column-0 {width:80px;}
.active-column-1 {background-color:threedlightshadow;}
.active-column-2 {text-align:right;width:80px;}

It this example, I want column 1 to stretch

I don't yet see any easy solution for this one. You need to listen to the grid resize event, calculate the column size and assign it to the stylesheet rule.
