How to set column sizes on Version 2.0?

On version 1.0, to set the columns sizes, it's used this:

<style>
aw-column-0 {width: 10%}
aw-column-1 {width: 90%}
</style>

And now? How to set column sizes on Version 2.0?

Thanks!

Doesn't it work something like this?
#myGrid .aw-column-[i]n[/i] {width: 10%;  text-align:center;}
  It works for sure with explicit pixel size:

#myGrid .aw-column-[i]n[/i] {width: 80px;  text-align:center;}
 

Great!

I'm forgot the name of #grid...

Thanks!
