using DataFrame.style loses all default table styling

Bug report for Colab: http://colab.research.google.com/.

For questions about colab usage, please use stackoverflow.

• Describe the current behavior:

Using the DataFrame.style in anyway completely removes all default table styling for dataframes.

See also this stackoverflow question

• Describe the expected behavior:

Using dataframe.style.apply and/or dataframe.style.applymap should add to the existing style, not remove all existing style. This is the default behavior in Jupyter.

Colab only applies the ‘dataframe’ styling to HTML table elements with the dataframe classname. The regular dataframe adds the dataframe class but the styler one does not.

The best approach is probably to explicitly add the dataframe class:

df.style.highlight_max().set_table_attributes('class="dataframe"')

This may possibly be addressed as part of https://github.com/pandas-dev/pandas/issues/41693?

Indeed, this is now fixed, and we forgot to close this issue. 😃
