DOC: Mention "StyleFrame" package in "DataFrame.to_excel()"

Pandas version checks

• I have checked that the issue still exists on the latest versions of the docs on main here

Location of the documentation

https://pandas.pydata.org/docs/reference/api/pandas.DataFrame.to_excel.html

Documentation problem

It is not a “problem” but enhancement.

Suggested fix for documentation

Do suggest the StyleFrame package to be more flexibel with formating the excel output.

btw: I won’t suggest to integrate StyleFrame into pandas. Formatting export outputs is not the job of pandas and I assume you agree with this. But is is an often mentioned “problem” in the internet community that the pandas excel output lacks of the possibility to formatting.

I’m not sure we want to be including third party libraries in the API docs unless it’s necessary - it seems to be blurring the lines between ecosystem and API docs. +1 on adding to the ecosystem page.

Just realized that the original point here was to add the external StyleFrame class to to_excel, not to the Ecosystem page. While it doesn’t seem a good idea to do that, looks like a good idea to add our pandas Styler to it. I created #48019 for it (I thought it was better to create a new issue better than reopen this).
