Description

Describe the bug clearly and concisely.

With the following Quarto document, I get an illegal unit of measure when generating a PDF but not for HTML or DOCX.

```{r}
require(gt)

data.frame(Group = c("Group 1", "% Group 2"), `% Total` = c(100, 61.4)) |>
    gt( rowname_col = "Group" ) |>
    tab_stub_indent( contains("%"), indent=2 )
```

Reproducible example

• Post a minimal reproducible example so the maintainer can troubleshoot the problems you identify. A reproducible example is:
  • Runnable: post enough R code and data so any onlooker can create the error on their own computer.
  • Minimal: reduce runtime wherever possible and remove complicated details that are irrelevant to the issue at hand.
  • Readable: format your code according to the tidyverse style guide.

See code chunk above. When running Quarto on this file, it produces the following output:
