add_source: line-height

[werkstattcodes]

I would like to change the vertical distance between two lines in a table's source, but the line-height seems not to work. Any idea? Many thanks!

library(reactable)
library(reactablefmtr)
library(tidyverse)

mtcars %>%
reactable() %>%
add_source(source=html("<span style='line-height:10%;'>This is a very long<br>long long text</span>"))
