#' Display a table in a window
#'
#' @param data a data object (either a `matrix` or a `data.frame`).
#' @param title Title to be displayed in window.
#' @param show_classes Show variables classes under variables names in table header.
#' @param type Display table in a pop-up with [shinyWidgets::show_alert()],
#'  in modal window with [shiny::showModal()] or in a WinBox window with [shinyWidgets::WinBox()].
#' @param options Arguments passed to [toastui::datagrid()].
#' @param width Width of the window, only used if `type = "popup"` or `type = "winbox"`.
#' @param ... Additional options, such as `wbOptions = wbOptions()` or `wbControls = wbControls()`.
#'
#' @note
#' If you use `type = "winbox"`, you'll need to use `shinyWidgets::html_dependency_winbox()` somewhere in your UI.
#'
#' @return No value.
