Add class to expanded column #1146
Description
When I went through the documentation, I did not see any props that allowed classes to be directly assigned to the showExpandColumn header column. By default it has no ID or classes assigned to it which makes adding styling to it somewhat difficult out of the box. This can be seen on a few of the expanded row storybooks.
Would it be potentially feasible to add a showExpandColumn column class prop similar to other column class props?
