Slice virtual column with show up if not empty

[Phong_Lam1]

Hi all I have a table master note, and create a table view for it

For the  3 column [ID Customer],[ID log],[ID Members] (they are ref column of table customer, table Log and Table Members) how could I create a virtual column with the expression that will show one of these three column if they have value (the logic is only 1 of them on the row have value). So I don't have to create 3 columns [ID Customer],[ID log],[ID Members] on the table view but just 1 virtual column only.

Thanks !
