flextable_to_rmd and pdf output is broken in 0.8.4

[pjledge]

flextable 0.8.4 is not producing valid LaTeX code, resulting in the following error when knitting a markdown document:

Error: LaTeX failed to compile test.tex. See https://yihui.org/tinytex/r/#debugging for debugging tips. See test.log for more info.

The underlying TeX code is:

\textbackslash global\setlength{\Oldarrayrulewidth}{\arrayrulewidth}

0.8.3 works fine. The following R markdown will cause the issue:

---
title: "Untitled"
output:
  pdf_document: default
  html_document: default
date: "2023-01-26"
---

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
library(flextable)
library(tidyr)

myfunc2 <- function() {
    m <- as.data.frame(matrix(rnorm(18*8), nrow=8))
    fmttable <- flextable(m)
    flextable_to_rmd(fmttable)
}

[davidgohel]

thanks, it should be fixed now.

[pjledge]
