JavaFX：无法填充表列中的整数值

基本上我试图用JavaFX中的一些字段填充表。我能够填充具有字符串数据类型的字段，但无法使用整数数据类型填充字段。任何人都可以抛出一些关于为什么整数字段未被填充的信息？以下是我创建的文件的代码。下面的代码应该做什么修改？JavaFX：无法填充表列中的整数值

没有代码'setItems（data）;'，也可以看一下Oracle官方教程（https://docs.oracle.com/javafx/2/ui_controls/table-view.htm），并且在这里问题（https://stackoverflow.com/questions/16360323/javafx-table-how-to-add-components） – GOXR3PLUS

终于有了解决办法！实际上，我的getter &序列号的setter方法与我在DataSource.java文件中声明的名称不匹配。只是改变在DataSource.java文件中的以下如下：

public int getSerialNo(){ 
     return serialNo.get(); 
    } 

    public void setSerialNo(int serialNum){ 
     serialNo.set(serialNum); 
    }

从串行更改为的SerialNo两个吸气& setter方法。最后它的工作！

您可以接受您自己的解决方案，将其标记为“解决问题”。下次我会推荐一个[MCVE] – c0der

@ c0der没有理由抱怨没有在这里发布必要的信息。问题中发布的信息足以确定问题的根源。自我接受只能在一些延迟（一天或两天（？））后才能完成。 – fabian

@fabian感谢您的反馈。我没有抱怨，但建议。我同意“问题中发布的信息就足够了”。事实上，我认为发布的信息太多了。这就是我推荐Mcve的原因。 – c0der
