email.setCellFactory(new Callback<TableColumn<CheckDo, String>, TableCell<CheckDo, String>>() {
@Override
public TableCell<CheckDo, String> call(TableColumn<CheckDo, String> p) {
return new TableCell<CheckDo, String>() {
@Override
public void updateItem(String item, boolean empty) {
super.updateItem(item, empty);
if (!isEmpty()) {
this.setStyle("-fx-background-color:red");
setText(item);
