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

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

## Arguments

name Column group header name. 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 info object as an argument. Render header content as HTML? Raw HTML strings are escaped by default. 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". 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. Additional CSS classes to apply to the header. 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.
