Rotated table headers
In my experience, these tables are difficult to read because the headings use {{vertical}}, which is fine for the other places where it's used on the site, but in table headings ends up rotating the text in the wrong direction.
Vertical table headings, as demonstrated at enwiki:Help:Table#Vertically_oriented_column_headers, should be rotated 90° counter-clockwise, and aligned to the bottom of the cell so that they all start in the same place. On Wikipedia there's a template, enwiki:Template:Vertical header just for that specific purpose. FeRDNYC (talk) 22:34, 19 November 2023 (PST)
