New Post: Page Order: Over, then down

Hi All!
I'm using PhpExcel ver 2.1, and I have a template excel (xls). In my template, I setted page order is "Over, then down". But affter call "save('php://output')" method then I receive a file with Page order has changed to "Down, then Over".
I don't know why!
Have you any solutions for me? Thanks!
