I'm not sure if you can find an official 3rd party python wrapper package to ease using curses for your exact need; but here is an roll-your-own example: the Window.py in pmemstat. You can see (from its README illustrations) that app has a fixed header, scrollable rows below, and commands to select rows, re-order the data, etc.; that is, I think it vaguely resembles what you want (and, if nothing else, the amount of code might suggest the effort of going that route).
There are some esoteric curses based spreadsheets which likely solve the want-it-in-a-terminal problem w/o any coding (e.g., hanishkvc/prgs-docs-spreadsheetkvc: A simple commandline spreadsheet based on curses and python, with support for authenticated encryption based csv files.).
