为什么多索引外部索引名称右对齐，而不是左对齐

Question

The below multi index data frame displays in jupyter lab with the outer indices 'O' and 'I' right justified. Whereas, in the cookbook https://pandas.pydata.org/pandas-docs/stable/user_guide/cookbook.html#cookbook-multi-index

..the outer indices appear left justified which makes more sense to me. Is there a setting I need to change to change the justification? Do other people run the code and see a different justification than the cookbook?

cols = pd.MultiIndex.from_tuples([(x, y) for x in ['A', 'B', 'C'] for y in ['O', 'I']])

df = pd.DataFrame(np.random.randn(2, 6), index=['n', 'm'], columns=cols)

Answer 1

I see the same as in the cookbook. Not sure where the issue is
