In hadley/pillar: Coloured Formatting for Columns

#' Format the body of a tibble
#'
#' @description
#' `r lifecycle::badge("experimental")`
#'
#' For easier customization, the formatting of a tibble is split
#' into three components: header, body, and footer.
#' The `tbl_format_body()` method is responsible for formatting the body
#' of a tibble.
#'
#' Override this method if you need to change the appearance of all parts
#' of the body.
#' If you only need to change the appearance of a single data type,
#' override [vctrs::vec_ptype_abbr()] and [pillar_shaft()] for this data type.
#'
#' @inheritParams rlang::args_dots_empty
#' @param x A tibble-like object.
#' @param setup A setup object returned from [tbl_format_setup()].
#'
#' @return
#'   A character vector.
