\title{Text highlight color}
\usage{
highlight(x, i = NULL, j = NULL, color = "yellow", part = "body", source = j)
}
\arguments{
\item{x}{a flextable object}

\item{i}{rows selection}

\item{j}{columns selection}

\item{color}{color to use as text highlighting color.
If a function, function need to return a character vector of colors.}

\item{part}{partname of the table (one of 'all', 'body', 'header', 'footer')}

\item{source}{if color is a function, source is specifying the dataset column to be used
as argument to \code{color}. This is only useful if j is colored with values contained in
other columns.}
}
\description{
Change text highlight color of selected rows and
columns of a flextable. A function can be used instead of
fixed colors.

When \code{color} is a function, it is possible to color cells based on values
located in other columns, using hidden columns (those not used by
argument \code{colkeys}) is a common use case. The argument \code{source}
has to be used to define what are the columns to be used for the color
definition and the argument \code{j} has to be used to define where to apply
the colors and only accept values from \code{colkeys}.
