Powerquery - Index column which restarts based on a grouped column
I have a table which contains 2000 entries. I want to add an index column to the table which will "reset" for each unique entrie in another column.
Hopefully the below table will help explain it
| Team Name | Library Name | Index |
|---|---|---|
| Team 1 | January | 1 |
| Team 1 | January | 2 |
| Team 1 | January | 3 |
| Team 1 | February | 1 |
| Team 1 | February | 2 |
| Team 1 | February | 3 |
| Team 1 | March | 1 |
| Team 1 | March | 2 |
| Team 1 | March | 3 |
| Team 1 | March | 4 |
| Team 1 | April | 1 |
| Team 1 | April | 2 |
| Team 1 | April | 3 |
| Team 1 | April | 4 |
| Team 1 | April | 5 |
I just can't get my head around how to achieve this. Any ideas would be appreciated.
