I'm trying to extend the current LWC Datatable to support dependent picklist during inline editing. 
In LWC Datatable during in line edit, I want to be able to refresh the values of the controlled field when a controlling field value changes. Is there a way to just refresh the cell where the controlled field resides? Reloading the entire table when the controlled field changes is not ideal since that will have huge impact on performance and will bring other problems.
Ideally I would like to reload just the cell but if that is not possible, is it possible to reload maybe an entire column or row without reloading the entire table?
