在两个表上的DragDropInfo SAP UI5

Question

我正在尝试在两个表而不是列表上实现dragDropInfo。但是，当我尝试使用oDraggedControl.getTitle（）来返回列表中被拖动项的名称时，将引发Tables错误。那么如何获取“拖曳”列并删除“列”名称？

onDrop: function (oEvent) {
var txt;
if (confirm("Do you want to tag this item?")) {
var sDropPosition = oEvent.getParameter("dropPosition");
var oDraggedControl = oEvent.getParameter("draggedControl");
var oDroppedControl = oEvent.getParameter("droppedControl");

var dragged = oDraggedControl.getTitle(); ---- throwing error
alert(dragged);

sap.m.MessageToast.show(
oDraggedControl.getTitle() +
" is dropped " +
" at the " +
oDroppedControl.getTitle()
);

var dropped = oDroppedControl.getTitle();
sap.m.MessageToast.show(dropped);
} else {
	txt = "Action Cancelled";
         alert(txt);
	}
}
