[displaytag-user] How do I export the total as well

[Li, Yanfei (Contractor)]

Title: Message

I am using the display TAG as,

<display:table name="sessionScope.PAGED_QUERY_RESULTS" id="fees" export="true" border="0" cellpadding="0" width="100%" cellspacing="0" grandTotCols="2,3,4,5" >

but the exported file does not include the grand totals. How can I make the total appears on the exported files (Excel, XML and CSV options are enabled)

Thanks,
