"``{=openxml} [caption]" keeps showing up in docx output

[claytonperry]

Hello! I'm running into an issue when trying to include captions on the flextables that I include in a Rmd I'm knitting to docx. Whenever I use the set_caption() function or 'tab.cap' option in the {r} chunk options I'm consistently seeing the caption included in a line that looks like "``{=openxml} [caption]" where the caption should be. Here's an example:

packages <- c("dplyr", "googlesheets4", "googledrive", "tidyr", "rmarkdown", "stringr", "knitr", "officedown", "flextable")

install.packages(setdiff(packages, rownames(installed.packages())), repos='http://cran.us.r-project.org')

#Call necessary packacges
lapply(packages, library, character.only = TRUE)

knitr::opts_chunk$set(echo=FALSE, warning=TRUE, message=FALSE, fig.cap=TRUE, tab.cap.style="Table Caption")

iris %>% 
    group_by(Species) %>%
    summarise(
        avg_sep_len = mean(Sepal.Length)
    ) %>%
    flextable() %>%
    set_caption(
        caption = "Average Sepal Length"
    )

and the docx that's output looks like this:

I've searched for a long time now and can't find someone who's had the same issue - I did find something of a lead in documentation from MNazarov: LINK but I'm not sure how to proceed. Here's my session info:

I'm super grateful for any advice you have! And apologies if I didn't find the answer out there in my searching.

Please try to install the last version

[claytonperry]

That did it - my apologies. Not sure why I didn't already have 0.8.0, I only installed flextable for the first time last week. Thank you!

[davidgohel]

No problem, you had the previous version and that bug has been fixed with latest version that is on CRAN since today :)
