Show district list as per country in SELECT editor of DATATABLE

Hi guys,
Currently, I am trying to display District based on Country for 2 Selection on the data table…

But I cannot get the value of each cell and set data for it based on the previous column. Anyone can give an example, thank you in advance!
data sample: const objData = {
“Country A”: [‘Country A-1’, ‘Country A-2’, ‘Country A-3’],
“Country B”: [‘Country B-1’, ‘Country B-2’, ‘Country B-3’],


Do you mean something like this Code Snippet?
