Customized borders cannot be exported to RTF files

[AlexZHENGH]

Prework

• Read and agree to the code of conduct and contributing guidelines.
• If there is already a relevant issue, whether open or closed, comment on the existing thread instead of posting a new issue.

Description

Customized table borders cannot be exported to RTF files.

Reproducible example

• Post a minimal reproducible example so the maintainer can troubleshoot the problems you identify. A reproducible example is:
  • Runnable: post enough R code and data so any onlooker can create the error on their own computer.
  • Minimal: reduce runtime wherever possible and remove complicated details that are irrelevant to the issue at hand.
  • Readable: format your code according to the tidyverse style guide.

library(gt)

tbl <- exibble |>
  gt(
    rowname_col = "row",
    groupname_col = "group"
  ) |>
  gt::tab_header(title="demo") |>
  tab_options(
    table_body.border.bottom.style = "solid",
    table_body.border.bottom.color = "black",
    table_body.border.bottom.width = px(2),
    
    heading.border.bottom.style = "solid",
    heading.border.bottom.color = "black",
    heading.border.bottom.width = px(2),
    
    footnotes.marks = c("[a]", "[b]"),
    page.orientation = "landscape"
  )
tbl

gtsave(tbl, 'demo-rtf-border.rtf')

Below is a screenshot of the exported RTF file.

Expected result

The borders are shown in the RTF tables.
