         width = 12,
         downloadableReactTableUI(
             id            = "object_id1",
             downloadtypes = c("csv", "tsv"),
             hovertext     = "Download the data here!")))),
     server = function(input, output) {
         table_state <- downloadableReactTable(
             id                 = "object_id1",
             table_data         = reactiveVal(iris),
             download_data_fxns = list(csv = reactiveVal(iris), tsv = reactiveVal(iris)),
             selection_mode     = "multiple",
             pre_selected_rows  = function() {c(1, 3, 5)},
             table_options      = list(columns = list(
                 Sepal.Length = colDef(name = "Sepal Length"),
                 Sepal.Width  = colDef(filterable = TRUE),
                 Petal.Length = colDef(show = FALSE),
                 Petal.Width  = colDef(defaultSortOrder = "desc")),
