Prework

• [x ] Read and agree to the code of conduct and contributing guidelines.
• [ x] If there is already a relevant issue, whether open or closed, comment on the existing thread instead of posting a new issue.
• [ x] Post a minimal reproducible example so the maintainer can troubleshoot the problems you identify. A reproducible example is:
  • [x ] Runnable: post enough R code and data so any onlooker can create the error on their own computer.
  • [x ] Minimal: reduce runtime wherever possible and remove complicated details that are irrelevant to the issue at hand.
  • [x ] Readable: format your code according to the tidyverse style guide.

Description

Using gtsummary::tbl_summary -> gtsummary::as_gt and then saving using gt::gtsave to write to docx. I find that the headers don't render correctly. Originally, I thought it was footnotes causing an issue but that isn't it.

library(gt)
library(gtsummary)

trial2 <- trial %>% select(trt, age, grade)
sumtab <- trial2 %>% tbl_summary()
sumtabnofoot <- sumtab %>% modify_footnote(all_stat_cols()~NA)

sumtab
sumtabnofoot

sumtab %>%
  as_gt() %>%
  gtsave("sumtab.docx")


sumtabnofoot %>%
  as_gt() %>%
  gtsave("sumtabnofoot.docx")

Expected result

Expected headings to be bolded and have a footnote in first example. Also expected some indentation to be present for sub categories.
