Crossref with interactive tables (e.g., DT::datatable)

[jack-davison]

Good afternoon,

I'm really enjoying using Quarto, so first a big thanks to the authors for putting it together! I'm especially enjoying the simplicity by which figures and tables can be labelled and cross-referenced, which brings me on to my query.

I'm a frequent user of the DT package for interactive tables. An issue in RMarkdown was the automatic labelling of DT::datatable() outputs as "Figure X: ..." - see issue here. There were some workarounds, but I can't seem to recreate them in a .qmd file.

Does Quarto contain a more straightforward workaround for "forcing" an interactive table to be seen as a table? Under-the-hood in the HTML they may not strictly be tables, but from a reader's perspective they are, and it'd be strange to have to label them figures.

Cheers!

Reproducible example

```{r}
#| label: tbl-dt
#| tbl-cap: "My DT table."
DT::datatable(iris)

Outputs:

An issue in RMarkdown was the automatic labelling of DT::datatable() outputs as "Figure X: ..."

Currently the limitation is the same as answered in #782 (comment).
They can be referenced as figures

```{r}
#| label: fig-dt
#| tbl-cap: "My DT table."
DT::datatable(iris)
```

DT and other interactive tables are htmlwidgets and "special" HTML table, they cannot be referenced as Table yet. We'll try to improve support for this in the future.
