I use the Table Editor node to substitute existing column names with new column names. I will not cover the exact workflow to inject the new column header.
I use the mentioned Table Editor node the following way: As an input serve a table with two column. The first column includes the old, existing column names und the second column is empty. This second column will then be filled interactively with the new column headers.
The downstream part will then inject the new headers.
My question: Is it possible to pick from a predefined list of values.? I.e. “new1” and “new2” are available within the picking list. Or ist there another way?
