1. Open https://openui5.hana.ondemand.com/entity/sap.ui.table.TreeTable/sample/sap.ui.table.sample.TreeTable.JSONTreeBinding

Did you mean the other sample https://sdk.openui5.org/entity/sap.ui.table.TreeTable/sample/sap.ui.table.sample.TreeTable.HierarchyMaintenanceJSONTreeBinding where DnD is enabled? This works with a real mobile/touch device and a long-press.
