没有显示FXML Tableview的JavaFX

Question

我一直在寻找我做错的事，但不知怎的，我错过了什么。我已经注释掉并重写了如此多的代码，以至于它开始变得一团糟（完全是我的错），所以希望我能找到解决方案。

我使用FXML表单制作攻击类对象列表。表单拉出，我键入所需的条目，点击添加攻击按钮，表格不填充。以下是相关代码：

涉及的课程

 public class Attack {

       import javafx.beans.property.SimpleStringProperty;

public class Attack {

    private final SimpleStringProperty weapon = new SimpleStringProperty("");
    private final SimpleStringProperty range= new SimpleStringProperty("");
    private final SimpleStringProperty damage= new SimpleStringProperty("");
    private int attackBonus;

    public String getRange(){return range.get();}
    public String getName(){return weapon.get();}
    public String getDamage(){return damage.get();}
    public int getAttackBonus(){return attackBonus;}

    public void setRange(String newRange){range.set(newRange);}
    public void setWeapon(String newName){weapon.set(newName);}
    public void setAttackBonus(int atkBonus){this.attackBonus = atkBonus;}
    public void setDamage(String dmg){damage.set(dmg);}




    Attack(String nameIn, int AB, String rangeIn, String damageIn){

      setWeapon(nameIn);
      setDamage(damageIn);
      setRange(rangeIn);
      setAttackBonus(AB);

    };

    Attack(){
       this("", 0, "", "");
    }
}

控制器类

        }

    }
