So let's I have a table with these values

| Name | Transportation |
| --- | --- |
| Mike | air |
| Sarah | car |
| Trevor | air |
| Carl | car |

I'd like each person to use each transportation mode so an outcome as such

| Name | Transportation |
| --- | --- |
| Mike | air |
| Mike | car |
| Sarah | air |
| Sarah | car |
| Trevor | air |
| Trevor | car |
| Carl | air |
| Carl | car |

I tried creating a list then exploding the values but I was having issues adding a list as column values. What's the best way to go about this?
