Group several rows into 1 according to a certain column, with filter still working

[Diana_Ning]

My data is like below:

Course No. | Language | State

AZ-999  | EN-US | To Do

AZ-999  | ZH-CN | Doing

AZ-999  | JA-JP | To Do

AZ-888  | EN-US | To Do

AZ-888  | ZH- CN| To Do

AZ-888  | ES- ES | Done

I need these to display like:

AZ-999 | EN-US, ZH-CN, JA-JP| To Do, Doing, To Do

AZ-888 | EN-US, ZH-CN, ES-ES| To Do, Done

While this still responding to the filter "Language" and "State".

I mean like below, when Languaage ES-ES is selected in the slicer, I want the "Languages" column in the table shows only the ES-ES, the languages column is generated using table.join

pls try this

_Language = CONCATENATEX('Table',[Language],", ")
_State = CONCATENATEX('Table',[State],", ")
