#' htmlTable with pagination widget
#'
#' This widget renders a table with pagination into an htmlwidget
#'
#' @param x A data frame to be rendered
#' @param number_of_entries a numeric vector with the number of entries per page to show.
#' If there is more than one number given, the user will be able to show the number
#' of rows per page in the table.
#' @param ... Additional parameters passed to htmlTable
#' @inheritParams htmlwidgets::createWidget
#' @import htmlwidgets
#' @return an htmlwidget showing the paginated table
#' @export
htmlTableWidget <- function(x, number_of_entries = c(10, 25, 100),
width = NULL, height = NULL, elementId = NULL,
...) {
rendered_table <- htmlTable(x, ...)
# forward options and variables using the input list:
input <- list(
thetable = rendered_table,
options = list(number_of_entries = number_of_entries)
)
# create widget

}
#' Shiny bindings for htmlTableWidget
#'
#' Output and render functions for using htmlTableWidget within Shiny
#' applications and interactive Rmd documents.
#'
#' @param outputId output variable to read from
#' @param width,height Must be a valid CSS unit (like `'100%'`, `'400px'`, `'auto'`) or a number,
#' which will be coerced to a string and have `'px'` appended.
#' @param expr An expression that generates a [htmlTableWidget()]
#' @param env The environment in which to evaluate `expr`.
#' @param quoted Is `expr` a quoted expression (with `quote()`)? This
#' is useful if you want to save an expression in a variable.
#'
#' @name htmlTableWidget-shiny
#'
#' @examples
#' \dontrun{
#' # In the UI:
#' htmlTableWidgetOutput("mywidget")
#' # In the server:
#' renderHtmlTableWidget({
#' htmlTableWidget(iris)
#' })
