这个呢,使用按钮扩展。我们定义了一个调用javascript函数的自定义按钮 page.len(-1) ,其中 -1 表示所有行:

shinyApp(

  ui = navbarPage(
    title = 'DataTable',
    tabPanel('Display length',     DT::dataTableOutput('ex2'))
  ),

  server = function(input, output, session) {

    output$ex2 <- DT::renderDataTable(
      DT::datatable(
        iris, 
        extensions = 'Buttons',
        options = list(
          dom = 'Bfrtip',
          lengthMenu = list(c(5, 15, -1), c('5', '15', 'All')),
          pageLength = 15,
          buttons = list(
            list(
              extend = "collection",
              text = 'Show All',
              action = DT::JS("function ( e, dt, node, config ) {
                                    dt.page.len(-1);
                                    dt.ajax.reload();
                                }")
            )
          )
        )
      )
    )

  }
)
