I think it could be regular python code that uses the Jupyter display system to display the information. The challenge is to figure out how to detect the pandas function calls and add the needed logic before and after. A good starting point might be to just monkey patch the relevant pandas calls and wrap them in the logic you need. That would allow you to get started quickly and explore the problem space.
