Highlights the maximum value in a column — highlight

The `highlight_max()` function assigns a font color and/or background color to the maximum value in a column. It should be placed within the style argument in reactable::colDef.

Usage

highlight_max(data, font_color = "green", highlighter = NULL)

Arguments

data: Dataset containing at least one numeric column.
font_color: color to assign to maximum value in a column. Default color is green.
highlighter: color to assign the background of a cell containing maximum value in a column.

Value

a function that applies a color to the maximum value in a column of numeric values.

Examples

data <- MASS::road[11:17, ]

## By default, the maximum value is bold with a green font color
reactable(data,
defaultColDef = colDef(
    style = highlight_max(data)))
#> Error in x$width %||% settings$fig.width * settings$dpi: non-numeric argument to binary operator

## Assign a different font color
reactable(data,
defaultColDef = colDef(
    style = highlight_max(data,
    font_color = "red")))
#> Error in x$width %||% settings$fig.width * settings$dpi: non-numeric argument to binary operator

## Highlight the background of the cell for the maximum value in each column
reactable(data,
defaultColDef = colDef(
    style = highlight_max(data,
    highlighter = "yellow")))
#> Error in x$width %||% settings$fig.width * settings$dpi: non-numeric argument to binary operator
