          Parameters
          ----------
          row : dict
              A normalized row.
          style : dict, optional
              A style that follows the schema defined in pyout.elements.  If
              None, `self.style` is used.
          adopt : bool, optional
              Merge `self.style` and `style`, using the latter's keys
              when there are conflicts.  If False, treat `style` as a
              standalone style.
  
          Returns
          -------
          A tuple with the rendered value (str) and a flag that indicates whether
          the field widths required adjustment (bool).
