I am using JDeveloper 10.1.3 and using JSF and ADF components.

I am using an af:table with af:tableSelectMany component. My problem is I need the sum of each column at the top of the table. I already have a header for each column. Is it possible to have another header. I have tried both table header and footer but neither gets displayed. (I also need to have inputText/date field in the footer). How to do this? Pls help, its urgent
