How add a column from a datatable to another datatable?

Hi,

have you tried using the Join Data Tables activity?

You might need to define a column with unique values like a primary key to both datatables to be able to join them properly. If no key is available, try adding an index column (Add Data Column, AutoIncrement True) to both datatables and join on that column.

Happy automating
