Typst: center tables by default

[vincentarelbundock]

maybe it would be nice to center align the table, as with kable?

LaTeX does centering by default, so it would be nice to be consistent and center Typst tables by default too.

What's the appropriate syntax? Should go in here: https://github.com/vincentarelbundock/tinytable/blob/main/inst/templates/typst.typ

[aghaynes]

#align(center,
[
#let nhead = 1;
....
]
)

This would conflict with #250 though... there i replace out[1] (#[) with [ and prepend the rotate. If you switch to center aligned, I suppose you'd need to wrap the rotate in align instead. Or maybe there's a more elegant way (something along the lines of gsub("#", "#rotate(-90deg,\\n[", out[1]))

Ultimately it would be something like this I suppose (for a rotated table)

#align(center,
rotate(-90deg, reflow: true,
[
#let nhead = 1;
...
]
)
)

or like this for a portrait one

#align(center,
[
#let nhead = 1;
...
]
)

Having written it like that, an easier solution for the rotated table presents itself, assuming you go with center aligned tables. If the template.typ file has a blank line in position 2, it could just be replaced with the rotate statement, and an extra closing bracket added to the end of the vector.

Shall I add it to #250 like that? Or do you want the alignment to be optional?

Thanks for the suggestion @aghaynes This was a good idea. Should be merged in Github dev version now.

This unfortunately doesnt seem to have worked... tables are still left aligned...

[aghaynes]

i think its interacting with the quarto stuff again... removing the tbl-cap and label seems to center align it... this is frustrating...

[vincentarelbundock]

Weird. This works on my computer:

---
format: typst
---

```{r}
packageVersion("tinytable")

library(tinytable)
tt(iris[1:3, 1:3], caption = "blah blah blah")

#| tbl-cap: blah blah blah
#| label: tbl-blah

library(tinytable)
tt(iris[1:3, 1:3], caption = "blah blah blah")

[aghaynes]

that does indeed work for me too... i'm sure i tested it like this though.

Maybe it's the template i'm using then... that same code within the template i'm using is left aligned... i'll investigate...

[aghaynes]

it's the echo option!

---
format: typst
execute:
  echo: false
---

```{r}
packageVersion("tinytable")

library(tinytable)
tt(iris[1:3, 1:3], caption = "blah blah blah")

#| tbl-cap: blah blah blah
#| label: tbl-blah

library(tinytable)
tt(iris[1:3, 1:3], caption = "blah blah blah")

#| tbl-cap: blah blah blah
#| label: tbl-blah2
#| echo: true

library(tinytable)
tt(iris[1:3, 1:3], caption = "blah blah blah")

I have no idea why this would change things. Maybe you can inspect the raw .typ file.

[aghaynes]

no idea why, but adding an empty r block into the .typ does the trick (but it also add the grey box to the PDF)

#block[
```r

figure([

The only difference between the code for these two tables is that r block (it's copy/pasted .typ code, not recompiled through knitr, only typst)
