coordinates must be a list of lists of tuples (each list corresponding to a single
                table-question pair).
            answer_text (`List[str]` or `List[List[str]]`, *optional*):
                Answer text of each table-question pair in the batch. In case only a single table-question pair is
                provided, then the answer_text must be a single list of one or more strings. Each string must be the
                answer text of a corresponding answer coordinate. In case a batch of table-question pairs is provided,
                then the answer_coordinates must be a list of lists of strings (each list corresponding to a single
                table-question pair).
        z"Table must be of type pd.DataFrameFNTr
