当我使用setAutoCreateRowSorter（）时，我的JTable得到一个无效范围异常。如果我删除setAutoCreateRowSorter，问题就会消失，但我无法对表进行排序。另外，如果我尝试直接设置分拣机：
myTable.setRowSorter(new TableRowSorter(model));
我仍然得到同样的错误。
这与我认为可以传达这个问题的SSCCE非常接近。

单击表格上的复选框时会出现问题。这与我认为可以传达这个问题的SSCCE非常接近。如果我带走分拣机，问题就不会持续存在。

This post是我能找到的最接近我问题的东西，但没有回答。如何在不收到此错误的情况下实现表格分类器？
