modified: pandas/core/reshape/pivot.py

	- Added condition to :func:`__internal_pivot_table` to aggregate `values` explicitly if `values` were passed, otherwise aggregate all remaining columns. This allows the tests :func:`test_pivot_table_values_in_columns` and :func:`test_pivot_table_values_in_index` in test_pivot_multilevel.py to pass.
