#' Check availability of columns
#'
#' Easy check for availability of columns in a data set. This makes it easy to get an idea of which antimicrobial combination can be used for calculation with e.g. [resistance()].
#' @param tbl a [`data.frame`] or [`list`]
2019-03-26 15:34:04 +01:00
#' @param width number of characters to present the visual availability, defaults to filling the width of the console
#' @details The function returns a [`data.frame`] with columns `"resistant"` and `"visual_resistance"`. The values in that columns are calculated with [resistance()].
#' @return [`data.frame`] with column names of `tbl` as row names
