xlsx file creation

[nitinpandirkar]

even if we specify fileext:".xlsx", the file generated is xls
so fileext parameter is not working in table2excel.js

I'm getting the same problem.
When I open the exported file, Excel prompts an error saying the format and the extension don't match.

Is there any solution for this issue?
