Description

Whilst Styler.hide_index() hides column header name (along with the index), the index name row persists when Styler.hide_columns() is used to hide column headers.

The index names rows should also be hidden, since currently there is no way to hide it independently.

What to do:

1. Find pandas/io/formats/style_render.py
2. Find the method for the StyleRenderer called _translate_header and read the documentation what it is trying to structure.
3. Go to the section in the method labelled # 2 and insert self.hide_columns_ into the conditional.
4. Add a test to pandas/tests/io/formats/style/test_style.py that addresses this.
