Return a new :class:`DataFrame` containing rows in this :class:`DataFrame` but
        not in another :class:`DataFrame` while preserving duplicates.

        This is equivalent to `EXCEPT ALL` in SQL.

        >>> df1 = spark.createDataFrame(
        ...         [("a", 1), ("a", 1), ("a", 1), ("a", 2), ("b",  3), ("c", 4)], ["C1", "C2"])
        >>> df2 = spark.createDataFrame([("a", 1), ("b", 3)], ["C1", "C2"])

        >>> df1.exceptAll(df2).show()
        +---+---+
        | C1| C2|
        +---+---+
        |  a|  1|
        |  a|  1|
        |  a|  2|
        |  c|  4|
        +---+---+

        Also as standard in SQL, this function resolves columns by position (not by name).
