Yes, Initially I thought setBeanType is better than setColumns for the
uniformity for generic class, but afterthought, setBeanType seems not so
good idea also.

My concern is rather purity of implementation. If we don't call
setBeanType(cls), the created object don't have any specific GUI info since
it has no info to create it.
So the initialization must be taken place at the setter setBeanType(cls),
for instance it will be :

void setBeanType(Class<?> cls) {
    this.cls = cls;

void initialize() {
    for (final Field field: cls.getFields()) {
             final String fname = field.getName();
             getColumns().add(new TableView.Column() {{
                    setWidth(3, true);

If setter is invoked twice, i will initialize twice (although we can use
some flag to avoid this, but I think it is ugly)

So conceptually, it is better to pass class object at the time of instance
