JavaFX TableView最后一列没有出现

Question

我需要将TableView中的每个单元格转换为JFXTextArea。前4列是完美的，让我输入文字。但第5列只是不可点击。当我点击它时，整个行都被选中。如何使第5列的行为与前4列相似？

FXMLController.java

 @FXML
     private TableView<Person> table1;
     TableColumn indexCol = new TableColumn("S. No.");
     TableColumn desCol = new TableColumn("Description");
     TableColumn quantityCol = new TableColumn("Quantity"); 
     TableColumn unitCol = new TableColumn("Unit/(SGD)"); 
     TableColumn totalCol = new TableColumn("Total (SGD)"); 

void fillTable(){
     indexCol.setSortable(false);
     desCol.setSortable(false);
     quantityCol.setSortable(false);
     unitCol.setSortable(false);
     totalCol.setSortable(false);
     indexCol.setPrefWidth(50); 
     table1.getColumns().addAll(indexCol, desCol, quantityCol, unitCol ,totalCol);
    ObservableList<Person> data;    
    data = FXCollections.observableArrayList(
    new Person("Jack", "", "","", ""),
    new Person("Tom", "", "","", "")
    );
    indexCol.setCellValueFactory(
    new PropertyValueFactory<Person,String>("firstName")
    );
    desCol.setCellValueFactory(
    new PropertyValueFactory<Person,String>("lastName")
    );
     quantityCol.setCellValueFactory(     
             new PropertyValueFactory<Person,String>("email")
    );             
    unitCol.setCellValueFactory(
             new PropertyValueFactory<Person,String>("remark")
    );  
    totalCol.setCellValueFactory(new PropertyValueFactory<Person,String>("total"));       
    table1.setItems(data);                         
}

Person.java

public class Person {
    private JFXTextArea firstName;
    private  JFXTextArea lastName;
    private  JFXTextArea email;
    private JFXTextArea remark;  
    private  JFXTextArea total;

    Person(String fName, String lName, String email, String value, String total1) {
        this.firstName= new JFXTextArea();
        this.firstName.setText(fName);
        this.firstName.setEditable(false);
        this.remark = new JFXTextArea();   
        this.lastName = new JFXTextArea(); 
        this.email = new JFXTextArea(); 
        this.total = new JFXTextArea(); 

    }

    public JFXTextArea getFirstName() {
        return firstName;
    }
    public void setFirstName(JFXTextArea fName) {
        this.firstName = fName;
    }

    public JFXTextArea getLastName() {
        return lastName;
    }
    public void setLastName(JFXTextArea fName) {
        this.lastName =  fName;
    }

    public JFXTextArea getEmail() {
        return email;
    }
    public void setEmail(JFXTextArea fName) {
        this.email = fName;
    }


 public JFXTextArea getRemark() {
        return remark;
    }

    public void setRemark(JFXTextArea remark) {
        this.remark = remark;
    }

    public void settotal(JFXTextArea fName) {
            this.total = fName;
        }
     public JFXTextArea gettotal() {
            return total;
        }

}
