cross reference to a table in rmarkdown with the correct table number in word document

I am trying to reference a table in a word document using bookdown package.

I wanted to add the reference id in the fig.cap parameter of the code chunk, but this is somehow not seen by the interpreter and I don't get the link to the reference.

As a workaround, I added my reference ID to the caption of the table, but here the full id ({#mysecondtable2}) is written in the figure caption and this looks ugly.

Any idea on how to solve this? Maybe LUA filter to remove the ugly anchor from the table caption? I don't understand how to do this.

---
title: "Untitled"
author: "Mario"
date: '2022-11-10'
output:
  bookdown::word_document2:
    toc: true
---

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

## R Markdown

See Table \@ref(tab:myfirsttable).  Or click [Table \@ref(tab:mysecondtable)](#mysecondtable2). 

```{r myfirsttable, echo = FALSE}
knitr::kable(cars, caption = "First three rows of cars dataset")
```

See Table \@ref(tab:mysecondtable).

```{r mysecondtable, echo = FALSE, fig.cap='{#mysecondtable2}'}
knitr::kable(head(iris, 3), 
             caption='{#mysecondtable2} test')
```

EDIT:

Some strange behaviour shows, that [Table \@ref(tab:mysecondtable)](#mysecondtable) seems to work. But actually it only refers to the caption of the second table but ignores the 2 at the end...

One straight-forward solution is to wrap the table into an extra div, as one can then link to that div:

Or click [Table \@ref(tab:mysecondtable)](#mysecondtable-wrapper).

::: {#mysecondtable-wrapper}
```{r mysecondtable, echo = FALSE}
knitr::kable(head(iris, 3),
             caption='test')
```
:::

A slightly less crude way is to put a span into the caption:

knitr::kable(head(iris, 3),
             caption='[test]{#mysecondtable}')

The difference between the two is that the link will point at the whole table when using a div, and to the caption when using a span.
