docs: Expect the specified column to exist.
  
          expect_column_to_exist is a :func:`expectation <great_expectations.data_asset.dataset.Dataset.expectation>`, not a \
          `column_map_expectation` or `column_aggregate_expectation`.
  
          Args:
              column (str): \
                  The column name.
  
          Other Parameters:
              column_index (int or None): \
                  If not None, checks the order of the columns. The expectation will fail if the \
                  column is not in location column_index (zero-indexed).
              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`.
