When i set the columnStretching=multiple to my table, the width of the columns is first set with the defined value in % and after the column stretching is applied at running time. The result of this is that the table is first rendered whit a small width (i put a random % of 5 to 14 columns) and then updated with the width stretched.

This happens only on firefox and just the first time the page is rendered. Afterwards is ok.
I'm using version 41.0.2, Chrome and IE works fine.
Any reason of this behavior?
Thanks
