I need to color the cell if the value of the cell is greater than 80. For example, given this data frame called df:

dput(df)

structure(list(Server = structure(1:2, .Label = c("Server1", 
"Server2"), class = "factor"), CPU = c(79.17, 93), UsedMemPercent = c(16.66, 
18.95)), .Names = c("Server", "CPU", "UsedMemPercent"), row.names = c(NA, 
-2L), class = "data.frame")

df[2,2] should be in red color. I was able to change the color of the text by something like this using xtable:

df[, 2] = ifelse(df[, 2] > 80, paste("\\color{red}{", round(df[, 2], 2), "}"), round(df[, 2], 2))

If I do this and print out the table with kable, it wont print out. Any ideas how can I color the cell in kable output table?

Another solution using my huxtable package:

library(huxtable)
ht <- as_hux(df)
ht <- set_background_color(ht, where(ht > 80), "red")
ht
