Ember table fixed columns from right

I am using ember table (http://ift.tt/1KxTHwF) for mytable component. I have setup everything and works fine. But I need to convert it ti arabic mode so that table should be inverse.

I can do that by inverting the column model. But numFixedColumnsis seems to be always from left. I need the fixed columns from right as well. Is that possible.

Your help is really appreciated

Thank You !
