Report Heading and Freezed Panes in Formatted Excel Attachment

Dear ABAP Gurus,

I have created a formatted excel attachment through IXML and it is giving column heading,data and colors in column heading. I want to get Report heading which will display what the table contains in Excel say 'Summary Report' etc. Also the file is having more columns and rows so I want that the key rows and Table columns should have freezed panes. How to achieve the same with the IXML code. I have searched in SDN but could not get success.

Kindly guide me in this matter.

Regards,
