 """ Expect values in column A to be greater than column B. Args: column_A (str):
 The first column name column_B (str):
 The second column name or_equal (boolean or None):
 If True, then values can be equal, not strictly greater Keyword Args: allow_cross_type_comparisons (boolean or None) : If True, allow comparisons between types (e.g. integer and\ string). Otherwise, attempting such comparisons will raise an exception. Keyword Args: ignore_row_if (str):
 "both_values_are_missing", "either_value_is_missing", "neither Other Parameters: result_format (str or None):
 \ Which output mode to use: `BOOLEAN_ONLY`, `BASIC`, `COMPLETE`, or `SUMMARY`. For more detail, see :ref:`result_format <result_format>`. include_config (boolean):
 \ If True, then include the expectation config as part of the result object. \ For more detail, see :ref:`include_config`. catch_exceptions (boolean or None):
 \ If True, then catch exceptions and include them as part of the result object. \ For more detail, see :ref:`catch_exceptions`. meta (dict or None):
 \ A JSON-serializable dictionary (nesting allowed) that will be included in the output without modification. \ For more detail, see :ref:`meta`. Returns: A JSON-serializable expectation result object.
