BUG: Multiple CSS selectors using set_table_styles and dict form of table_styles · Issue #44011 · pandas-dev/pandas (original) (raw)

• I have checked that this issue has not already been reported.
• I have confirmed this bug exists on the latest version of pandas.
• I have confirmed this bug exists on the master branch of pandas.

Reproducible Example

import pandas as pd df = pd.DataFrame([range(5) for _ in range(5)], columns=list('abcde')) styled = df.style.set_table_styles({ 'b': [{'selector': 'th, td', 'props': [('border-left', '2px solid black')]}] })

styled = df.style.set_table_styles({

'b': [{'selector': 'th', 'props': [('border-left', '2px solid black')]},

{'selector': 'td', 'props': [('border-left', '2px solid black')]}]

})

html = styled.render() with open('css_style_bug.html', 'w') as f: f.write(html)

Issue Description

This is a minor issue when styling a table for html display. When setting a table style for a specified column using set_table_styles, the column is only applied to the final selector tag if they are named in a comma seperated list.

This seems to be similar to issue #34061.

Expected Behavior

I have commented out, in the above examples, a workaround which does the expected behaviour.
