Description

Hi,

Thanks for all your work on Quarto and on this forum!

When a package produces markdown tables, the tbl-subcap functionality works as expected. However, when the package produces a LaTeX table, there is no subcaption.

Is it possible for Quarto to support subcaptions in LaTeX tables as well?

I'd love to get some clarification on this.

1. Are subcaptions only supported for markdown tables?
2. Are there plans to extend support for LaTeX tables as well?

Thanks!

```{r}
#| label: tbl-example
#| tbl-cap: "Example"
#| tbl-subcap: 
#|   - "Cars"
#|   - "Pressure"
#| layout-ncol: 2

library(tinytable)
tt(head(cars)) |> save_tt("markdown") |> knitr::asis_output()
tt(head(pressure)) |> save_tt("markdown") |> knitr::asis_output()
```

This doesn't work:

library(tinytable)
tt(head(cars)) |> save_tt("latex") |> knitr::asis_output()
tt(head(pressure)) |> save_tt("latex") |> knitr::asis_output()
```</div>

Hello! @cscheid
I have an issue with tbl-subcap in a python jupyter notebook. It's not rendering the sub-captions. This is the code cell:

#| label: tbl-shapiro
#| layout-ncol: 2
#| tbl-cap: "Shapiro-Wilk test: Cloudy vs Clear conditions"
#| tbl-subcap:
#|    - Temperature
#|    - Humidity

from tabulate import tabulate
from IPython.display import display, Markdown


...

display(Markdown(tabulate(tbl_shapiro_t, headers="firstrow", tablefmt="latex")))
display(Markdown(tabulate(tbl_shapiro_h, headers="firstrow", tablefmt="latex")))

These are the raw latex outputs:

\begin{tabular}{lrr}
\hline
        &   W-statistic &     p-value \\
\hline
 Cloudy &      0.89371  & 4.16354e-11 \\
 Clear  &      0.919841 & 2.24352e-09 \\
\hline
\end{tabular}

\begin{tabular}{lrr}
\hline
        &   W-statistic &     p-value \\
\hline
 Cloudy &      0.924261 & 5.56431e-09 \\
 Clear  &      0.840152 & 4.37101e-14 \\
\hline
\end{tabular}

Thanks for your help.
