[PHP] PHPExcel 資料匯出大小限制

發布日期
這個限制讓我Debug三個小時......

將資料匯出成Excel時，超過一定數量Excel的內容就一片空白，資料消失。

本來以為是自己code的問題，奮戰很久.......

結果竟然是因為先天性就有限制......


引述 stackoverflow 一位大大的言論：

The only PHPExcel limit for worksheets size is 65,536 rows and 256 (IV) columns (when using the Excel5 Writer); or 1,048,576 rows and 16,384 (XFD) columns (when using the Excel2007 Writer).
各位一定要注意啊......

 使用PHPExcel的時候，

 如果是使用Excel5 Writer "PHPExcel_Writer_Excel5"，最大列為 65,536，最大欄為 256 (IV)。

 如果是使用Excel2007 Writer "PHPExcel_Writer_Excel2007"，最大列為 1,048,576，最大欄為 16,384 (XFD)。
