JXTreeTable中的可变大小行

Question

是否可以在JXTreeTable中使用可变大小的行，如果可以，那么如何使用?我正在尝试在TreeExpansionEvent上更改行的高度(如下所示)：

public void treeExpanded(TreeExpansionEvent e)
{
      for (int i = 0; i < table.getRowCount(); i++) {
            System.out.println("Value of img"+table.getValueAt(i,22));

            if (table.getValueAt(i, 22) != null) {
                table.setRowHeight(i,40);
            table.repaint();
            table.revalidate();

            }
        }
}

在运行代码时，我得到以下异常：

Exception in thread "AWT-EventQueue-0" java.lang.UnsupportedOperationException: variable height rows not supported
    at org.jdesktop.swingx.JXTreeTable.setRowHeight(JXTreeTable.java:1321)

请帮帮我！

JXTreeTable不支持可变行高。setRowHeight()状态的文档：

会抛出UnsupportedOperationException，因为不支持可变高度的行。
