Description:

 """Render fields with values from `row`. 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). """
