Pandas version checks
-
[X] I have checked that this issue has not already been reported.
-
[X] I have confirmed this bug exists on the latest version of pandas.
-
[X] I have confirmed this bug exists on the main branch of pandas.
Reproducible Example
import pandas as pd
import numpy as np
import matplotlib as mpl
df = pd.DataFrame([[38.0, 2.0, 18.0, 22.0, 21, np.nan],[19, 439, 6, 452, 226,232]],
index=pd.Index(['Tumour (Positive)', 'Non-Tumour (Negative)'], name='Actual Label:'),
columns=pd.MultiIndex.from_product([['Decision Tree', 'Regression', 'Random'],['Tumour', 'Non-Tumour']], names=['Model:', 'Predicted:']))
# works in loc
df.loc[("Non-Tumour (Negative)", ...)]
def highlight_max(x,):
return np.where(x == np.nanmax(x.to_numpy()), f"color: blue;", None)
# works with columns
df.style.apply(highlight_max, subset=("Non-Tumour (Negative)", df.columns), axis=0)
# not work with ellipsis
df.style.apply(lambda x: x, subset=("Non-Tumour (Negative)", ...), axis=1)
Issue Description
Subset parameter is documented as A valid 2d input to DataFrame.loc[<subset>]
But when subset rows in styler, ellipsis not works.
Expected Behavior
subset=("Non-Tumour (Negative)", ...) works the same as subset=("Non-Tumour (Negative)", df.columns)

This needs consideration about how to restructure the Styler columns/rows selection code, or a re-documentation.
