kableExtra：为行名添加脚注 [kableExtra, Rmd]

Question

I'm using the kableExtra library with R Markdown, I would like to add footnotes to the row labels (and secondary, to other cells). How can I do that?

Data example below:

library(kableExtra)
tab = data.frame(matrix(NA, 5,5))
rownames(tab) = paste("info", 1:5)
kable(tab)

I want to add a footnote to info 1 , the label of the 1st line (for example).

Any ideas?

Thanks in advance

You can use footnote from kableExtra :

dt <- mtcars[1:5, 1:5]
footnote(knitr::kable(dt, "html"), alphabet = c("Note a", "Note b"))
