Exporting to rtf with column spanner

[moleps]

I tried exporting one of the examples to rtf, but the column spanner is lost somewhere in the process.

---

library(gt)

airquality_m <- 
  airquality %>%
  mutate(Year = 1973L) %>%
  slice(1:10)

gt_tbl <- 
  gt(data = airquality_m) %>%
  tab_header(
    title = "New York Air Quality Measurements",
    subtitle = "Daily measurements in New York City (May 1-10, 1973)"
  ) %>%
  tab_spanner(
    label = "Time",
    columns = vars(Year, Month, Day)
  ) %>%
  tab_spanner(
    label = "Measurement",
    columns = vars(Ozone, Solar.R, Wind, Temp)
  )

writeLines(as_rtf(gt_tbl),"t1.rtf")

Now - when I open t1.rtf I get:

Am I missing something here or is this feature not implemented in the rtf output?

Column spanner labels are supposed to work with RTF. I will take a look at this and implement a fix.

Sorry this took well over a year but a fix is now in place (#638) in the development version of gt. I tried the code again and opened the RTF in Word. Here is a screenshot.
