kable

Suppose the next example: library(knitr) library(kableExtra) df <- data.frame(a = letters[1:10], b = 1:10) names(df) <- c("This is a looooooong title, I don't know how to handle this... Also, I'm trying to extend this title even more... This column name will be used to compute vertical space","I want to align vectically this column name") df %>% kable(format = 'latex', linesep = "", align = 'c') %>% kable_styling(full_width = T) How can align vertically the second column name? I am not sure if there is an easier way, but you can go with the multirow package: --- title: "Test Book" header

Is there a way to change the font of a kable in Rmarkdown when knitting to pdf? I can find plenty on changing size or bold etc but not on changing the actual font. I would just like something sans serif. Example markdown doc: --- title: "R Notebook" output: pdf_document: default --- Change the font in the table below: ```{r message=FALSE, warning=FALSE, echo=FALSE} library(kableExtra) mtcars %>% head() %>% kable() ``` Default table output font You can use the Latex fontspec library , see below. Note that you can see your available fonts and their names in the Fonts page from Settings. ---

I have just learnt KableExtra and know to how to use conditionally formating the entire column using mutate() as explained in the doc using mutate such as: mutate( mpg = cell_spec(mpg, background = ifelse(mpg > 20, "red", "blue")) ) But what I don't know is, how to change background colours of only certain rows in each column whilst all rows are being displayed. For example, my data: df <- data.frame( region1 = c("A", sample(1:5,3)), region2 = c("B", sample(1:5,3)), region3 = c("C", sample(1:5,3)), region4 = c("A", sample(1:5,3)) ) Now I want to format only second and third row. I dont want to

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
