Code Sample

df = pd.DataFrame(np.zeros((2, 2), dtype=int))
df.columns.name = 'columns.name'
df.to_html(index_names=False)

Output

columns.name 0 1
0 0 0
1 0 0

Problem description

from the docs:

index_names : bool, optional
Prints the names of the indexes, default True

The problem occurs with both standard and MultiIndex columns index. The expected behavior is observed on the (row) Index, if it has names they are not displayed.

Expected Output

0 1
0 0 0
1 0 0

Output of pd.show_versions()

[paste the output of pd.show_versions() here below this line]
