Filtering column for empty cell (using faceted values or another method)

[kennsorr]

Using MUI Datagrid Pro, you can filter for empty table cells. I haven't seen a way to do this in Material React Table. Is there a way to get the [empty] value in the faceted filter options list?

i.e. In this table, there are some recored with no states, but all of the options are states:

Can you just add an empty string value to the list? Also there is an empty filter mode in the filter modes feature.

It looks like an empty string value gets tossed out. I guess I could used something like '--' and filter for that.
