Padding does not appear on pdf

[FarahKhandwala]

Hello, I am new to flextable and having trouble rendering my padding settings to pdf. The following appears correctly in the viewer:

df <- structure(list(
type = c("glop glop", "glop glop" , "glop glop", "pas glop pas glop", "pas glop pas glop"),
what = c("Group", "Age", "Residence", "Smoker", "Europe"),
1 = c(63, 25, 25, 15, 15),
2 = c(23, 53, 53, 74, 11),
3 = c(85, 22, 43, 13, 15)
),
row.names = c(NA, -5L),
class = c("data.frame"))

as_grouped_data(df, groups = "type") %>%
as_flextable() %>%
add_footer_lines("Observed event") %>%
set_header_labels(what = "") %>%
color(part = "footer", color = "#800000") %>%
bold( bold = TRUE, part="header") %>%
padding(i = ~ is.na(type), padding.left = 20) %>%
bold(i = ~ !is.na(type)) %>%
autofit()

but when I render to pdf through quarto, I lose the indent. (In fact if I try any padding settings they do not seem to do anything):

PDF does not support padding, you can use \t instead

library(flextable)
library(magrittr)

df <- structure(list(
  type = c("glop glop", "glop glop" , "glop glop", "pas glop pas glop", "pas glop pas glop"), 
  what = c("Group", "Age", "Residence", "Smoker", "Europe"), 
  `1` = c(63, 25, 25, 15, 15), 
  `2` = c(23, 53, 53, 74, 11),
  `3` = c(85, 22, 43, 13, 15)
), 
row.names = c(NA, -5L), 
class = c("data.frame"))

as_grouped_data(df, groups = "type") %>%
  as_flextable() %>%
  add_footer_lines("Observed event") %>%
  set_header_labels(what = "") %>%
  color(part = "footer", color = "#800000") %>%
  bold( bold = TRUE, part="header") %>%
  prepend_chunks(i = ~ is.na(type), 
                 as_chunk("\t")) %>%
  bold(i = ~ !is.na(type)) %>%
  autofit()
