Problem when rending a flextable to Beamer presentation

[dr-phuong]

Hi,

I encountered similar issues in this post when rendering a flextable in a Beamer presentation.

The problem:

Surprisingly, it worked fine in knitting all other document formats like Word, PDF, PPTX, and HTML, except for Beamer. And I can also knit everything to beamer (text, figure, tables by kable), except a flextable. So the problem is only knitting a felxtable to beamer presentation.

Note: I tried this Rmd file on three computers, 2 Mac Pro (1 intel, 1 M1) and 1 Dell, and they all showed the same error below.

So I was wondering if there is a bug either in flextable or TinyTex.

I also tried to seek public support in Stack in this post Still, I would appreciate it if you could have a chance to check if there is any bug/issue in flextable. Thank you in advance!

Example codes:

---
output:
  beamer_presentation: default
  pdf_document: default
  powerpoint_presentation: default
  ioslides_presentation: default
  word_document: default
---

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

## Slide
```{r echo=FALSE, results='asis'}
example_ft <-
  iris |> head() |> 
  flextable()
example_ft
```

Error:

Yesterday you cross posted this on 3 diff websites and tagged me when possible. This is spam

The original issue already states it is not working, it is open, it states also 'help needed', can't you read?

Insisting does not make things done and is irritating. If you go on, you will be banned from this repo

Update:

A partial solution is posted in Stack

By using the older version of flextable (ver 0.6.6) I can knit it into beamer presentation.

OK I am banning you

The previous version is using an image as written in the original post
