OK, nowość w Javie od kilku tygodni, ale programuję od 30 lat. Wykonywany jest następujący kod, ale tylko pierwsza kolumna pokazuje cokolwiek. Obiekt danych pokazuje wiele wierszy danych z wypełnionymi polami danych. Jestem pewien, że czegoś brakuje i przejrzałem podobne pytania tutaj.

Dziękuję za Twoją odpowiedź. Droga do wielu lat w językach niewrażliwych na sprawy. To było dla mnie szybkie i brudne ćwiczenie, aby nauczyć się Java i najnowszych i najlepszych rzeczy lub, jak lubię mówić, Nowa ekscytująca technologia (NExT!)

Dla każdego, kto patrzy na odpowiedź i nadal nie jest w pełni skupiony, oto zmiany, które sprawiły, że kod działa poprawnie.

colDateEntered.setCellValueFactory(new PropertyValueFactory<sresult, String>("Denteredon"));
colDescription.setCellValueFactory(new PropertyValueFactory<sresult, String>("CDesc"));
colEnteredBy.setCellValueFactory(new PropertyValueFactory<sresult, String>("Ccreatedby"));


    public class sresult {

        private String Denteredon;
        private String Ccreatedby;
        private String CDesc;

        public sresult(String T, String d, String c) {
            this.Ccreatedby = T;
            this.Denteredon = d;
            this.CDesc = c;
        }

        public String getCcreatedby() {
            return Ccreatedby;
        }

        public void setCreatedby(String T) {
            Ccreatedby = T;
        }

        public String getDenteredon() {
            return Denteredon;
        }

        public void setDenteredon(String d) {
            Denteredon = d;
        }

        public String getCDesc() {
            return CDesc;
        }

        public void setCDesc(String c) {
            CDesc = c;
        }
    }
}
