Research direction

Start by reproducing printlabels(df) in a Jupyter notebook and compare its text output with the DataFrame's HTML display. Then investigate how large DataFrames and all-column output should behave, including compatibility with @less from TerminalPager.jl; done means an agreed IO-aware metadata-printing design is implemented and verified in these contexts.

Written by the indexing model from the issue text.

Description

Currently when running Dataframes in a Jupyter notebook, the data frame prints out in html form properly, but when you do printlabels(df) you get a boring text representation.

Plus in general, it would be really nice to have a way to deal with very large data frames and print labels for all columns, maybe to make it compatible with DataFrame that can be viewed with @less from TerminalPager.jl.
