Answer 1

Try with this code below

onAddButton: function(oEvent){
        var columnListItemNewLine = new sap.m.ColumnListItem({
            cells:[
                new sap.m.Text({text: "1"}),
                new sap.m.TextArea({value: "senf", rows: "6", width: 
                "30%"}),
                new sap.m.Input({type: "text", placeholder: "bla"}),
                new sap.m.Input({type: "text", placeholder: "bla2"}),
                new sap.m.DatePicker({placeholder: "bla3"}),
                new sap.m.Datepicker({placeholder: "bla4"})
                ]
        });
        this._oTable.removeAllItems();
        this._oTable.addItem(columnListItemNewLine);
    }
