How to put a crossreference in Rbookdown?

I am not sure I understand this part from the documentation

the table label for a code chunk with the label foo will be tab:foo

Say I have a RMarkdown chunck such as

```{r mytable, echo=FALSE}
kable(df, booktabs=T)
```

I would consider mytabel as the label for the code chunck. That means I should be able to type a narrative that looks like:

This is my table \@ref(tab:mytable)

And the \@ref should reference the table number instead of the chucnk id. Instead I get a double (and clickable) ?? .What am I doing wrong?

In the second paragraph of the documention:

Like figures, tables with captions will also be numbered and can be referenced.

So you want to cross-reference a table, you must specify the caption argument.

You can create a empty RStudio project and or save following code as index.Rmd file. Or download https://github.com/yihui/bookdown-minimal and replace the content of index.Rmd file with the following code. Then you can press Build Book button in the Build panel.

title: "A Book"
author: "Frida Gomam"
site: bookdown::bookdown_site
output:
  bookdown::gitbook: default

# reference

This is my table \@ref(tab:mytable)

# table

```{r mytable, echo=TRUE}
knitr::kable(iris[1:10, ], booktabs=T, caption='A table of the first 10 rows of the mtcars data')
```
