Pandas does not set column width (In Jupiter Notebook /Lab)

Question

I want to show each row of pandas DataFrame in One line, and as I searched, it seems the solution is to set the display column width as None. However, it does not do the job for me.

Here is a test code to show the problem. I need to have each row in a single line (so basically I expect it to increase the columns width to a point where 'It issssssssssssssssss justttttttttttttttttttttt a tesssssssssssst' is shown in one line and not multiple lines).

import pandas as pd
pd.set_option('display.max_colwidth', None)
A=pd.DataFrame(['It issssssssssssssssss justttttttttttttttttttttt a tesssssssssssst', 'It is just a test'] )
df=pd.concat([A,A,A,A,A,A,A,A], axis=1)
df

One option (the only one?) is to change the CSS white-space to "nonwrap" with set_properties :

(
    df
        .set_axis(range(len(df.columns)), axis=1)
        .style.set_properties(
            **{"white-space": "nowrap"}
        )
)

Output :

Update :

With jupyter notebook, you can make a custom.css and put it in the default-config-dir :

.dataframe td {
    white-space: nowrap;
}

The tree should look like this (in Windows) :

C:
┗━━ Users
    ┗━━ Timeless
        ┗━━ .jupyter
            ┣━━ custom         # <-- make a new folder
                ┗━━ custom.css # <-- put there the css

Output :
