Issues with group_tt() and notes in Quarto + typst

[maibennett]

Hi! I'm working on a document using Quarto + typst, and for some reason the tables are not rendering as they do in the console. Here's a short example (the .qmd file) that is similar to what I'm trying to do:

---
title: "Example tiny table"
format:
  typst:
    toc: false
    section-numbering: 1.1.a
    columns: 1
---

```{r, echo=FALSE, message=FALSE, warning=FALSE}
library(dplyr)
library(tinytable)

@tbl-tab1 is the table I want, but when rendering the document, the groups do not appear (they do appear on the console if I print the table there.)

#| label: tbl-tab1
#| tbl-cap: "lorem ipsum"

df = data.frame(Meas = rep(c("meas1 (\\$)", "meas2 (pts)", "meas3"), 2),
                y1 = c(1:3, 6:8),
                y2 = c(1:3, 6:8) + 1,
                y3 = c(1:3, 6:8) + 2,
                y4 = c(1:3, 6:8) + 5)

tt(df) %>% style_tt(j=1:ncol(df), align = "lrrrr") %>% format_tt(escape = TRUE) %>% style_tt(fontsize = 0.8) %>%
  group_tt(i = list("Var1" = 1,
                    "Var2" = 4))

Same thing with @tbl-tab2 and notes.

#| label: tbl-tab2
#| tbl-cap: "lorem ipsum"

tt(df, notes = "Notes: This is a note") %>% style_tt(j=1:ncol(df), align = "lrrrr") %>% 
format_tt(escape = TRUE) %>% style_tt(fontsize = 0.8)

If I run each chunk of code, they print fine on the console:

But they don't render correctly, and both group_tt() and the notes option are ignored:

If anyone knows why this could be happening, I'd really appreciate it! Thanks 

PS: This is a beautiful package, so thank you for all the work on this

Thanks for taking the time to craft an example. I'll look into it when I get back home to my computer.

With the latest from GitHub, it looks like things are working OK. The only thing to be careful about is that we should not escape the \\$ manually in the creation of the data frame if we're going to use format_tt(escape=TRUE). Typst does not play well with double escapes, apparently. So you need:

df = data.frame(Meas = rep(c("meas1 ($)", "meas2 (pts)", "meas3"), 2),
                y1 = c(1:3, 6:8),
                y2 = c(1:3, 6:8) + 1,
                y3 = c(1:3, 6:8) + 2,
                y4 = c(1:3, 6:8) + 5)

Also, I noted two limitations of Typst that came up in my tests: lack of indentation and row-specific alignment. I'll look into those in separate issues:

Thanks for the quick response! I'll update appropriately :) (I double escaped because typst was complaining before)
