order of operations is causing the problem here.
Unreal requires the column “row name”. This column is how rows are looked up.
Easiest way to work is like this:
- create your struct
- create data table from struct
- export data table as csv
- import csv to your spreadsheet editor program
- export when ready
- reimport to unreal
if you need a display name, it’s probably better to not use the RowName, but make a separate column.
