Fixed Column width if the View column changing

First of all thank you all for this great library. Its just awesome.

Is this possible to have fixed columns width if the `View column` changing? For now columns get all available width and the data of table a bit jumps.
Is there some way to make columns width fixed?

I try to override styles but it not helps.

## Expected Behavior
It would be great if we could have fixed column width option

## Current Behavior
For now columns get all available width of the table.
