Empty column at the end of grid

I read several posts that point out this problem and looks like the behavior of AW when there's extra space available for the grid to fill-up it creates this empty column (as explained by Alex). Is there a way to make the last data column take up the rest of the space and make this empty column go away or make it inconspicuous?
e.g., can i specify something else for width for column 10 below (aw-column-9) to take up the remaining space of the grid?

#sTable .aw-row-selector { display:none; }
#sTable .aw-column-0 {text-align: right; width:10em;}
#sTable .aw-column-1 {text-align: center; width:10em;}
#sTable .aw-column-2 {text-align: center; width:10em;}
#sTable .aw-column-3 {text-align: center; width:7em;}
#sTable .aw-column-4 {text-align: center; width:6em;}
#sTable .aw-column-5 {text-align: center; width:6em;}
#sTable .aw-column-6 {text-align: center; width:9em;}
#sTable .aw-column-7 {text-align: center; width:5em;}
#sTable .aw-column-8 {text-align: center; width:5em;}
#sTable .aw-column-9 {text-align: center; width:15em;}

No. The only solution is to calculate the widths in javascript and assign the column width dynamically based on the current grid width.
