[Need Help] How to customize the grid style

[eotin]

Describe the bug

I would like to customize my table / dataGrid and was able to do it with the version 3.x of the bundle.
It looked like this :

I did the upgrade of my app and use the latest version of the bundle (v4.11) but i'm not able to redefine the css for the grid.

I'm using webpack-encore , i'm able to redefine some variables but not for the grid.

Thanks for your help
