Table API overhaul: computational subtables?

[cscheid]

I don't think we have support for this ATM, but we should, since we're on tables anyway.

[cscheid]

subtables and subcaptions interact with crossref, so 1.4.

[cscheid]

See also #1580. In Quarto 1.4's upcoming crossref system, these are instances of the same problem.

We're not doing a perfect job at this just yet.

With explicit layouts

It works great:

---
title: tables
keep-md: true
---

```{r}
#| label: tbl-tables
#| layout-ncol: 2
#| tbl-cap: "Tables!"

knitr::kable(head(iris), caption="Caption 1 {#tbl-tables-1}")
knitr::kable(head(cars), caption="Caption 2 {#tbl-tables-2}")

See @tbl-tables, especially @tbl-tables-1 and @tbl-tables-2.

## Without explicit layouts

The code cells get in the way:

---

title: tables keep-md: true

#| label: tbl-tables
#| tbl-cap: "Tables!"

knitr::kable(head(iris), caption="Caption 1 {#tbl-tables-1}")
knitr::kable(head(cars), caption="Caption 2 {#tbl-tables-2}")

See @tbl-tables, especially @tbl-tables-1 and @tbl-tables-2.

## `tbl-subcap` still doesn't work either

This is now working on main.

Can someone show a reproducible example of how to get two tables next to each other in python? I cannot figure it out.

::: {#tbl-panel layout-ncol=2}
```{python}
#| layout-ncol: 2

Markdown(tabulate(
    df, headers=df.columns, showindex=True))

Markdown(tabulate(
    df, headers=df.columns, showindex=True))
