我是素颜的新手。我在 dataTable 上有一个复选框和文本框值。而 dataTable 将从数据库加载数据。请在下面查看我的代码

        public KooTable getSelectedCar() {

        }  

        public void setSelectedCar(KooTable selectedCar) {  
            this.selectedCar = selectedCar;  
        }  
}

这是我的问题。当我单击查看按钮时，我需要获取每一行值，包括复选框值是否选中复选框或 nt 然后更新到数据库。可能吗？
