sap.ui.table.Table : Fixed first Row

Hello Experts,

my sap.ui.table.Table's first row is the total of all the other rows.

I want that to be fixed and not affected by any sort/filter.

var oTableNASummary = new sap.ui.table.Table("idTableNASummary",{

            columnHeaderHeight: 40,

            selectionMode: sap.ui.table.SelectionMode.None,

            width:"100%",

           visibleRowCount: 100,

            //height: "35px",

    }).addStyleClass("abcstyle");

Is it possible?

Thanks,

Seyed Ismail MAC
