\title{Footnote marker}
\usage{
footnote_marker_number(x, format)

footnote_marker_alphabet(x, format)

footnote_marker_symbol(x, format)
}
\arguments{
\item{x}{a number. For example, for \code{footnote_marker_alphabet(2)} will
return "b" in HTML.}

\item{format}{Either \code{html} or \code{latex}. All functions here can read
default value from global option \code{knitr.table.format}.}
}
\description{
Put footnote mark in superscription in table. Unless you are
using it in the \code{caption} of \code{kable}, you will need to put \code{escape = F}
in \code{kable} (similar with \code{cell_spec}). Again, similar with \code{cell_spec}, the
\code{format} option here can read default value from global option
\code{knitr.table.format}.
}
\examples{
dt <- mtcars[1:5, 1:5]
colnames(dt)[1] <- paste0("mpg", footnote_marker_alphabet(2, "html"))
rownames(dt)[2] <- paste0(rownames(dt)[2], footnote_marker_alphabet(1, "html"))
footnote(knitr::kable(dt, "html"), alphabet = c("Note a", "Note b"))
