Question

我从一个闪亮的例子开始研究这个谷歌形式，它已经扩展了我想对数字输入进行排序并显示用户何时保存数据的最后一个ID = rowname = entry，其他数值变量很明显。你可以在服务器上看到我的失败，如果有人知道如何在关闭之后运行下一个块我会很感激。

也很抱歉葡萄牙语，如果你想让我在表格框中翻译一些东西，请随时询问。

如果我理解你，你需要将服务器中的提交部分更改为：

# When the Submit button is clicked, save the form data
  observeEvent(input$submit, {
    saveData(formData())
    updateSelectInput(
      session = session,
      inputId = "df_picker",
      choices = names(which(unlist(eapply(.GlobalEnv,is.data.frame))))
    )
  })

如您所见，您需要更新您的输入，我也会更改获取数据帧的代码，而您的变体不起作用..
