JTable排序 - 选择一行

我有一个JTable，其中我使用整数比较器以及TableRowSorter trs.setComparator(columnIndex, new IntComparator())和table.setRowSorter(trs)进行排序。JTable排序 - 选择一行

排序按预期工作，但我有一个鼠标点击事件，它使用int row = table.rowAtPoint(e.getPoint())和DefaultTabelModel mod = (DefaultTableModel)table.getModel()来获得用mod.getValueAt(row, 0)所选行的值。

这会获得在JTable的原始排序中此位置的行的值，而不是排序后现在存在的行的值。我怎样才能使这个工作的排序表以及？

感谢
