Rotate column labels

[david-waterworth]

Is it possible to rotate column labels by 90 degrees? I have a large pivot table and both the row and col labels are longish (and the values a single digit counts or "-" (Null) so to make it somewhat more readable I'd like to rotate the column labels?

@david-waterworth , you could try adding some custom CSS like the code below:

import polars as pl
from great_tables import GT, html


(
    GT(pl.DataFrame({"longish": [1, 2]}))
    .cols_label(longish=html('<h3 style="transform: rotate(90deg);">longish</h3>'))
    
)
