 def expect_file_to_have_valid_table_header(self, regex, skip=None, result_format=None, include_config=False, catch_exceptions=None, meta=None):
 """ Checks to see if a file has a line with unique delimited values, such a line may be used as a table header. Keyword Args: skip (nonnegative integer):
 \ Integer specifying the first lines in the file the method should skip before assessing expectations regex (string):
 A string that can be compiled as valid regular expression. Used to specify the elements of the table header (the column headers) 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. Exact fields vary depending on the values passed to :ref:`result_format <result_format>` and :ref:`include_config`, :ref:`catch_exceptions`, and :ref:`meta`. """
