How to generate a permutations or combinations of n rows in m columns?

Does anyone know how to create a table with m columns from table of n rows where the values in columns of each row represent a different combination or permutation of values from the original table?

For example the original table has 1 column (number_value) with 3 (n=3) rows:

1
2
3

The table which contains combinations (the order doesn't matter) of two values (m = 2) would be the following:

number1, number2
1,2
1,3
2,3

and the table of permutations would be the following:

number1, number2
1, 2
2, 1
1, 3
3, 1
2, 3
3, 2

The order of rows doesn't matter.

Thank you in advance!
