This package is particularly interesting when calculating tables using the tables() function. For example, we might want to calculate the number of cases that we have for all the combinations of career and age, and then paint that column on a green color scale:

formattable(data,align =c("c","c","c","c"), list("Person" = formatter("span", style = ~ style(color = "grey",font.weight = "bold")), "Salary"= color_tile(Green, Green2), 
"Contacted" = formatter("span", style = x ~ style(color = ifelse(x, "green", "red")), 
 x ~ icontext(ifelse(x, "ok", "remove"), ifelse(x, "Yes", "No"))))) 

The following screenshot shows the output (the contacted column now contains ticks and crosses):
