【问题描述】：
是的，你可以。您需要获取所有表的对象并在所有对象上触发导出功能。示例代码如下：
function exportAllDatatables() {
var table = $('#myTable').DataTable();
var table2 = $('#myTable2').DataTable();
//Trigger the button at index 2-1 (Wherever your export button in each table):
table.button( '2-1' ).trigger();
table2.button( '2-1' ).trigger();
}
此处引用导出按钮的触发功能： https://datatables.net/reference/api/button%28%29.trigger%28%29
【讨论】：
-
如果你能提供一个小提琴就太好了
-
如何合并这两个表？以及如何在 PDF 中显示这些数据？
-
请做一些研究，自己尝试一些代码，在问题中添加一些代码，并更新您的问题，了解究竟什么不起作用以及您尝试了什么。我给了你
trigger函数的代码示例，这对你的情况很有用。
是的，即使有按钮集合也是可能的。 这是高级演示https://jsfiddle.net/4kpvba23/4/（可以同时导出两个或多个表的csv、excel、pdf）
正如 Kavish Mittai 所指出的，您也可以在集合中触发单个按钮或多个按钮。
按钮 API (https://datatables.net/reference/api/button())
按钮 API (https://datatables.net/reference/api/buttons())
按钮触发 API (https://datatables.net/reference/api/buttons().trigger())
注意：记得点击全部导出会提示“允许多次下载？” 在浏览器中以避免有害下载，这取决于用户 交互你不能禁用它。

是的，它适用于多个数据表和多个 PDF、Csv 等，但我需要一个 PDF 中的所有表意味着在单个 PDF 文件中导出两个或多个数据表。这可能吗？
