TODO:

• [x] check test failures
• [x] make sure this works with align"d"

[vincentarelbundock]

Does not work, with or without the options.

options("modelsummary_format_numeric_latex" = "plain")
library(modelsummary)
dat <- transform(
  mtcars,
  cyl = factor(cyl),
  gear = factor(gear)
)
datasummary_balance(~am, data = dat, align = "lllllldd", stars = TRUE)

tab_fac not wrapped in \num{} because we format with wtcpct. This may not be a problem because percentages and counts are always positive, so we don't need thw fancy negative signs provided by \num{}
