Viewing Pandas data frames

**Is your feature request related to a problem? Please describe.**

I’m debugging some code, and I’d like to look at Pandas data frames ([docs](https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.html)) more comfortably.

**Describe the solution you'd like**

Not too sure, but perhaps a popup window that renders the df as a table, and that can scroll horizontally through the columns and vertically through the rows 🤔

**Describe alternatives you've considered**

- The variable view or the command line (ctrl-x) kinda sorta work but it’s not very convenient for large numbers of rows/cols.
- According to this [SO discussion](https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.html) copying the df as a CSV to the clipboard ([docs](https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.to_clipboard.html)) is an alternative solution that has worked ok. But that requires switching around between the terminal (with pudb) and a CSV viewer…
