adding summary data to exported excel sheet and make certain rows as bold

pallavid

Hi,
I could not find a way to add a summary to the excel sheet exported.
I am able to do this for pdf using sPdfMessage. Is there a way to achieve this for excel too ?

Also, how to render certain data as bold.
Would really appreciate any help. I am using Datatables for the first time.

Thanks,
Pallavi
