如何使用table2excel.js插件将HTML表下载到Excel中

When I download the table, I get the message: "Excel cannot open the file 'Test.xlsx' because the file format or file extension is not valid.

When I manually change the name of the downloaded file to 'Test.xls', I'm able to open the file fine (with a small warning that the file format and extension don't match).
