Question

我想通过选择组合框项目从数据库中显示tableview中的数据。 Combobox包含我的数据库中的列，用户可以选择这些列。我试试这个，组合框没问题，代码工作没有错误，但表格没有更新。

控制器类：

/auth/register

表类：


    package application;

    public class tableAngajati {
        private String numesediu;
        private int angajati;


        public tableAngajati(String numesediu, int angajati) {
            super();
            this.numesediu=numesediu;
            this.angajati=angajati;
        }

        public String getNumesediu(){
            return numesediu;
        }

        public void setNumesediu(String numesediu){
            this.numesediu=numesediu;
        }

        public int getNumarangajati(){
            return angajati;
        }

        public void setNumarangajati(int angajati){
            this.angajati=angajati;
        }

    }

非常感谢！
