只有最后一列填充了javafx + FXML

Question

在填充表格视图列时，仅填充最后一列，不显示其他列。

这是控制器类，其中填充了表视图，

列出patientList = new ArrayList＆lt;＆gt;（）;

        try {
            System.out.println("I am in table records");

                for (AddPatientDto addPatientDtoCopy : editPatientService.fetchPatientsRecord())
 {
                System.out.println(addPatientDtoCopy.getPatinet_id() + addPatientDtoCopy.getFirstName()+ addPatientDtoCopy.getMiddleName()+
                        addPatientDtoCopy.getLastName()+ addPatientDtoCopy.getAreaInp()+ addPatientDtoCopy.getQualification());

                patientList.add(new PatientDto(addPatientDtoCopy.getPatinet_id(), addPatientDtoCopy.getFirstName(), addPatientDtoCopy.getMiddleName(),
                        addPatientDtoCopy.getLastName(), addPatientDtoCopy.getAreaInp(), addPatientDtoCopy.getQualification()));

}
            ObservableList<PatientDto> observeTableDataList = FXCollections.observableArrayList(patientList);
            System.out.println(observeTableDataList.subList(0, 14));
            TableColumn patient_id = new TableColumn("PatientID");
            patient_id.setMinWidth(100);
            patient_id.setCellValueFactory(new PropertyValueFactory<PatientDto, String>("Patient_id"));
            patient_id.setVisible(true);
            TableColumn first_name = new TableColumn("FirstName");
            first_name.setMinWidth(100);
//            patient_name.setCellValueFactory(new PropertyValueFactory<AddPatientDto, String>("first_name" + " " + "middle_name" + " " + "last_name"));
            first_name.setCellValueFactory(new PropertyValueFactory<PatientDto, String>("first_name"));
            first_name.setVisible(true);
            TableColumn middle_name = new TableColumn("MiddleName");

            TableColumn patient_location = new TableColumn("Location");
            patient_location.setMinWidth(100);
            patient_location.setCellValueFactory(new PropertyValueFactory<PatientDto, String>("Area"));
            patient_location.setVisible(true);
            TableColumn patient_qualification = new TableColumn("Qualification");
            patient_qualification.setMinWidth(100);
            patient_qualification.setCellValueFactory(new PropertyValueFactory<PatientDto, String>("Qualification"));
            patient_qualification.setVisible(true);
            patientsDetails.setItems(observeTableDataList);
            patientsDetails.getColumns().setAll(patient_id, first_name, middle_name, last_name, patient_location, patient_qualification);
            patientsDetails.setVisible(true);
            System.out.println("End of table records");
        } catch (Exception e) {
            e.printStackTrace();
