### Adding a caption errors

tt(mtcars, caption = "foo") |> 
  save_tt(dest, overwrite = TRUE)

Thanks for the report.

The root of the issue is that we use the standalone LaTeX package to save a cropped table to file, but that package does not easily seem to accommodate floats with captions.

I need to do an overhaul of captions for all formats (see https://github.com/vincentarelbundock/tinytable/issues/208), but it might take me a little while.

Thanks again for the report. Should be fixed on Github. This code:

library(tinytable)
x <- mtcars[1:5, 1:5]
tt(x, caption = "A simple table with caption.", width = .6) |>
    save_tt("example.pdf", overwrite = TRUE)

Generates this file:

example.pdf
