missing reference for flextable table in word document

[rmflight]

Bug description

---
title: "flextable missing reference"
format: docx
---


```{r}
#| label: load_data
data(cars)

library(flextable)
```

Now lets try a table in our word document. This should be @tbl-cars.

```{r}
#| label: tbl-cars
#| tbl-cap: Something about cars.
cars |>
  dplyr::slice_head(n = 5) |>
  flextable() |>
  autofit()
```

flextable_missing.docx

Rendering the above document (RStudio render button) results in the table reference looking like ?@tbl-cars, and there is no caption.

If I force HTML output (quarto::quarto_render(..., output_format = "html")), I get the expected output of Table 1, as well as the caption.

Software details:

• R 4.2.1
• RStudio 2022.12.0-preview+348
• quarto 1.3.47
• flextable 0.8.4.001 2022-12-08 davidgohel/flextable@f38ccb1
• Linux, Pop! OS 22.04 (skinned version of Ubuntu 22.04)

In Quarto 1.4's crossref system, this is a duplicate of #1556, #2297, #3397 and #3600.

There's something not quite right with flextable and quarto just yet that I haven't figured out. Specifically, this document produces output that Microsoft Word doesn't like much. If you tell it to go ahead and read the file anyway, though, the output generated seems correct:

If I use output other than flextable (like gt in #3600), I don't get the warning. This is a crossref bug with quarto+flextable specifically, because if I use flextable outside of a crossreferenceable environment, I don't get the warning either.

I'm going to close this bug and open a new, more specific one.

@cscheid I do get the warning with example in #3600 using gt. We can discuss tihs in the new issue #7321 but it seems to happen with gt too for me.

Just wanted to share to be thorough.
