java - JTable 编辑/取消编辑代码不适用于重新排列的 JTable 列

Question

我使用以下代码对 JTable 列进行编辑/取消编辑，但是当用户重新排列列时，以下代码不起作用 SSCCE的代码如下:

    import javax.swing.JTable;
    import javax.swing.table.DefaultTableModel;
    import javax.swing.table.TableModel;

    public class Main {
    public static void main(String[] argv) throws Exception {
    TableModel model = new DefaultTableModel() {
    public boolean isCellEditable(int rowIndex, int mColIndex) {
    boolean flag = false;
            if (isEdit == true) {    
                if ((vColIndex == tblItem.getColumn("Design").getModelIndex())
                        || (vColIndex == tblItem.getColumn("ChangedCategory").getModelIndex())
                        || (vColIndex == tblItem.getColumn("Amount").getModelIndex())) {
                    flag = false;
                } else {
                    flag = true;
                }
            } else {
                flag = false;
            }    
            return flag;
  }
};

JTable table2 = new JTable(model);
}
}

Answer 1

请注意，模型索引和 View 索引不等效。如前所述here ,

JTable provides methods that convert from model coordinates to view coordinates — convertColumnIndexToView and convertRowIndexToView — and that convert from view coordinates to model coordinates — convertColumnIndexToModel and convertRowIndexToModel.

教程部分讨论 Sorting and Filtering行，但该原则也适用于列。缺少complete example ，很难确定。
