Is a kable() col heading with side by side special symbols possible?

This is not a question about printing distinct kable() tables side by side.

Working in Markdown, PDF output. I have a column heading that is the Greek symbol delta. I want to add a column the heading of which is the Greek symbol delta side-by-side with the % symbol, but I cannot figure out how to achieve this.

Here's what I've got:

test_results <- dplyr::data_frame ('First Score'=c(42.35), 'Second Score'=c(90.4), '$\\Delta$'=c(48.05))

kable(test_results, align = "ccc", caption = "Test Results Data", format="latex", position = "h!", escape = FALSE) %>% row_spec(0,bold=TRUE) %>% 
kable_styling()

Thanks for any help!

Not really sure where you want the % sign, so assuming it is required after the delta, try this.

```{r }

library(kableExtra)
library(tibble)

test_results <- tibble ('First Score'=c(42.35), 
                               'Second Score'=c(90.4), 
                               '$\\Delta$\\%'=c(48.05))

kable(test_results, 
      align = "ccc",
      caption = "Test Results Data", 
      format="latex", 
      position = "h!", 
      escape = FALSE) |> 
  row_spec(0,bold=TRUE) |>  
  kable_styling()


```

Which gives:
