#' Check availability of columns
#'
#' Easy check for availability of columns in a data set. This makes it easy to get an idea of which antibiotic combination can be used for calculation with e.g. \code{\link{portion_IR}}.
#' @param tbl a \code{data.frame} or \code{list}
#' @return \code{data.frame} with column names of \code{tbl} as row names and columns: \code{percent_IR}, \code{count}, \code{percent}, \code{visual_availability}.
