Df.style.applymap gives error since a few days

EDIT: It has to do with the upgrade to the new pandas 1.3.0 from 1.1.4 what I used before. Apparently there is now a Styler object and I guess my code is not backwards compatible :frowning:

EDIT 2: it has been solved, hopefully it will be soon active at share.streamlit.io DataFrame Styling not working when using pandas 1.3.0 · Issue #3526 · streamlit/streamlit · GitHub


This code gives an error since a few days. Locally everything is allright and before there were no problems

Expected output
