This may be a very dumb question, but I cannot seem to see the output of the Pandas Styler. I use the following simple example posted previously by another user.

The dataframe styling will only be rendered in Jupyter notebooks. Your code, for instance, looks like this:
You can experiment with notebooks on tmpnb.org if you don't have it installed.
