I'm having trouble finding guidance on this. I want to create a dataset that has a variable called "location" and contains the values 1, 3, 4, 6, 7 with another variable called "action" that contains values1, 2, 3, 4, 5. I want my dataset to contain every combination of these, but I do not want to input manually. Any ideas?

location action
1 1
1 2
1 3
1 4
1 5
3 1
3 2
...
