Rendering with css fails

Hey there,

I am trying to replicate the dashboards from the user guide ( According to the guide, adding

app.css.append_css({"external_url": ""}) to the code should give a differently rendered output, but on my computer it just does not work.

I tried to add app.css.config.serve_locally = True and app.scripts.config.serve_locally = True for offline / firewall usage, but nothing changed.

This is how my table looks like:

Thank you very much for your help in advance :slight_smile:
