Input Table Schema
The table can have additional columns, but the function ignores them.
|comb||VARCHAR||Combination, represented by space-separated player numbers. For example, '1 2' or '2 3 4 5'. First player is number 1, second is number 2, and so on.
For correct Shapley values, the comb column values must be unique.
|value||DOUBLE PRECISION||Assigned value of combination.|
