Format any cell based on value

[rjake]

Just found gt and really like it. Using all the select helpers is 👌
The only thing I haven't found is a simple solution to format cells of any column based on the cell value. In my app, the number of columns will vary based on the user's selection. In this reprex, I want to bold any value <= 5.

Some of the solutions I've found weren't easy to implement:
This solution uses rlang + purrr

This one uses a for loop across each column:

I was hoping to use something like:

tab_style(
  style = ...,
  locations = cells_body(
    columns = ...,
    condition = ~(.x <= 5))
  )
)

I hope you'll consider adding a helper function to make this easy to do. Thanks for all the hard work.

library(gt)

set.seed(123)
matrix(sample(1:30, 30), 3, 10) %>% 
  as_tibble() %>% 
  gt()

This seems like something that ought to be possible (and I would like this feature a lot). Thank you for suggesting it. I’m hoping that our ongoing work in improving the tidyselect support/semantics in this package will pave the way for your suggested code to work.
