Default columns widths

Is these a way to change the default column width in the style without having to set each individually as in:
.aw-column-0 {width: 10px;}
.aw-column-1 {width: 10px;}
.aw-column-2 {width: 10px;}
.aw-column-3 {width: 10px;}
etc. etc.

I don't want to set each column individually in the <style> or in JavaScript as the number of columns are dynamic (1 up to 200 columns).

Is there something like this available? :- .aw-column-All {width: 10px;}

This should work -

.aw-grid-cell,
.aw-grid-header,
.aw-grid-footer {width: 10px}
