Hi all,  I use the Export to Excel button build-in control bar of Data Grid, and the column number is greater 300+, which caused error below Caused by: java.lang.IllegalArgumentException: Invalid column index (256).  Allowable column range for BIFF8 is (0..255) or ('A'..'IV') then, I found the excel generated by the Export button is 2003 version.    How can I generate excel with 2007+ version which allow more column numbers?
