When you click the "export to excel" hyperlink, the contents of all pages will be exported to excel. However, we may not want the "export to excel" hyperlink to appear in Excel. In order to prevent it from appearing, we add a judgment condition to judge whether the exportToExcel parameter appears. If it does, it means that the content will be exported to excel, and hyperlinks will not be included. On the contrary, it means that we just want the browser to display the web page, so the hyperlink will appear on the page.
