Find some quick prototype as starter help here, based on a generic dataset
Join_1Col_MergeBoth_AddCols.xaml (11.0 KB)
Just give a play by renaming the column names as by your case.
- check also the ColList variable, for configuring the final result list columns
- Constraints: Join Col to keep is the first column from Join DataTable
A later more dynamizing should be possible
