Notebook comparing DataFrame._html_repr_ to DataFrame.style

I think we're identical for non-truncated DataFrames. That' has not been implemented in Styler yet.

Along the way I noticed two other things that ended up needing fixing.

  1. DataFrame.columns.names were not displayed
  2. CSS classes weren't being assigned correctly to row labels.

The fixes ended up being pretty intertwined, so I've put them in a single PR. Unfortunately, the commits are a bit jumbled as well :/

maybe put a ref to the style docs (e.g. not sure how much of an example is needed here)

@jreback this was undocumented... Adding this section to the notebook. Will push soon.

CSS Classes

Certain CSS classes are attached to cells.

  • Index and Column names include index_name and level<k> where k is its level in a MultiIndex
  • Index label cells include
    • row_heading
    • row<n> where n is the numeric position of the row
    • level<k> where k is the level in a MultiIndex
  • Column label cells include
    • col_heading
    • col<n> where n is the numeric position of the column
    • level<k> where k is the level in a MultiIndex
  • Blank cells include blank
  • Data cells include data

'column names' -> 'column level names' ? ('column names' sounds like the columns labels itself)

👍 DataFrame.style will now show column level names (e.g. DataFrame.columns.names) (:issue:13775)
