>>> df = pd.DataFrame({'A': [1, 2], 'B': [3, np.nan]})

        After any added style:

        >>> df.style.highlight_null(color='yellow')  # doctest: +SKIP

        Remove it with:

        >>> df.style.clear()  # doctest: +SKIP

        Please see:
        `Table Visualization <../../user_guide/style.ipynb>`_ for more examples.
