Math symbols in Table caption

[giorgiopaulon]

I am interested in exporting a flextable to a .pdf document using Quarto / Markdown. The only resources I found suggest to use the following

#| tbl-cap: !expr sprintf("A caption with some math, $\\gamma \\geq 0.5$, ($N = %s$)", nrow(iris))
head(iris) %>% 
  flextable()

However, this results in the following

Quarto manage captions instead of the packages. We only emit an empty caption https://github.com/davidgohel/flextable/blob/master/R/captions.R#L252

I am afraid we can't help.

It is indeed a Quarto bug.
