PDF Output does not support background colors
Description
PDF output does not include background colors of cells (text colors are not affected by this). The problem seems to be an underlying issue with how {webshot2} aka {chromote} aka Chrome browsers print documents. It seems that by default browsers will not include background CSS (at least that's what this SO answer says).
I can confirm that when I want to print a {gt} table from Chrome manually, I will not get background colors. It is only when I activate the "Background graphics" option in the print window of Chrome, then I get my desired output. So a solution would be to let {chromote} know that it should use that setting when printing something. I couldn't find a way to pass any meaningful option like that to gtsave() to get the desired result.
Reproducible example
library(gt)
tbl <- towny |>
dplyr::slice(1:5) |>
dplyr::select(name, land_area_km2) |>
gt() |>
tab_style(
style = cell_text(color = 'dodgerblue4'),
locations = cells_body(columns = 1)
) |>
tab_style(
style = list(
cell_fill(color = 'dodgerblue4'),
cell_text(color = 'white', weight = 'bold')
),
locations = cells_body(columns = 2)
)
gtsave(tbl, 'img.png') # Works fine
gtsave(tbl, 'img.pdf') # No Background colors
