如何从表模型中获取选定的行？
我尝试了以下...
checkBoxes[t].addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
int index = -1;
for (int i = 0; i < checkBoxes.length; i++) {
if (checkBoxes[i] == e.getSource()) {
String Status=null ;
DbUtility ViewAbsenties=new DbUtility();
ViewAbsenties.loadDriver();
ViewAbsenties.connect();
TableModel tm;
tm = table3.getModel();
if (checkBoxes[i].isSelected() == true) {
Status =(String) tm.getValueAt(i,8);
System.out.println("Status : " + Status );
}
}
}
}
}
当我运行上面的代码时，iam收到以下错误。

最佳答案
存在三个潜在问题
JTable视图可能是Sorted or Filtered，那么您必须convertRowIndexToModel
以零（getValue(0, 0）开头的数组是1st. row中的1st. column）
必须正确设置javax.swing.ListSelectionModel或确定所有选定的行
