Use colGroup() to create column groups in a table.

## Usage

colGroup(
name = NULL,
columns = NULL,
html = FALSE,
align = NULL,
sticky = NULL,
)

## Arguments

name

columns

Character vector of column names in the group.

Custom header renderer. An R function that takes the header value as an argument, or a JS() function that takes a column object and table state object as arguments.

html

Render header content as HTML? Raw HTML strings are escaped by default.

align

Horizontal alignment of content in the column group header. One of "left", "right", "center" (the default).

Vertical alignment of content in the column group header. One of "top" (the default), "center", "bottom".

sticky

Make the column group sticky when scrolling horizontally? Either "left" or "right" to make the column group stick to the left or right side.

If a column group is sticky, all columns in the group will automatically be made sticky.

Inline styles to apply to the header. A named list or character string.

Note that if headerStyle is a named list, property names should be camelCased.

## Value

A column group definition object that can be used to create column groups in reactable().

## Examples

reactable(
iris,
columns = list(
Sepal.Length = colDef(name = "Length"),
Sepal.Width = colDef(name = "Width"),
Petal.Length = colDef(name = "Length"),
Petal.Width = colDef(name = "Width")
),
columnGroups = list(
colGroup(name = "Sepal", columns = c("Sepal.Length", "Sepal.Width")),
colGroup(name = "Petal", columns = c("Petal.Length", "Petal.Width"))
)
)
