This worked in 6.5.0: https://codesandbox.io/s/datatable-with-nicefilter-and-columngroups-working-0rzfb

I left NiceTableFilter there to verify that the custom filterFunction works. It's just a MultiSelect filter that allows picking from the values in the corresponding column data. And together with niceFilterFunction it conflates null, undefined and "" to a single "Not set" option. From the 6.5.0 codesandbox:

The description misses the fact that filters used to be rendered in the corresponding header cells, that's not the case anymore: there is filterDisplay="row" and filterDisplay="menu" now. Both don't work with ColumnGroups. In the menu mode the menu button and overlay show up, but the overlay has no filter fields:

Another reproducer in 9.2: https://stackblitz.com/edit/react-szwyss-osqzwu

Is there any news about this issue? I am currently using version 10.2.1 and I cannot render the filters when using filterDisplay="row" together with the headerColumnGroup prop.
