    A Row object is returned when a Table object is indexed with an integer
    or when iterating over a table::

      >>> from astropy.table import Table
      >>> table = Table([(1, 2), (3, 4)], names=('a', 'b'),
      ...               dtype=('int32', 'int32'))
      >>> row = table[1]
      >>> row
      <Row index=1>
        a     b
      int32 int32
      ----- -----
          2     4
      >>> row['a']
      2
      >>> row[1]

        Returns a *read-only* copy of the row values in the form of np.void or
        np.ma.mvoid objects.  This corresponds to the object types returned for
        row indexing of a pure numpy structured array or masked array. This
        method is slow and its use is discouraged when possible.

        Returns
        -------
        void_row : ``numpy.void`` or ``numpy.ma.mvoid``
            Copy of row values.
            ``numpy.void`` if unmasked, ``numpy.ma.mvoid`` else.
