java - 基于另一个表，使用卡住第一列对 JTable 进行排序

Question

我制作了第一列卡住的表格，我的意思是 - 第一列不可滚动，与 MS Excel 中的工作方式相同。

问题是，我不知道如何使用行排序器同时对两个表进行排序。现在排序适用于每一列，除了第一列，卡住列。

有人可以给我一些线索或解决方案吗？非常感谢

我的代码基于这个例子:

import java.awt.Dimension;
import java.beans.PropertyChangeEvent;
import java.beans.PropertyChangeListener;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.JViewport;
import javax.swing.event.ChangeEvent;
import javax.swing.event.ChangeListener;
import javax.swing.table.DefaultTableModel;
import javax.swing.table.TableColumn;
import javax.swing.table.TableColumnModel;

public class TestClass extends javax.swing.JFrame {
    private DefaultTableModel tableModel;
    private javax.swing.JScrollPane jScrollPane;
    private javax.swing.JTable jTable;
    private javax.swing.JTable freezeTable;
    private int fixedColumns = 1;//number of colums to be freezed

public TestClass() {
        jScrollPane = new javax.swing.JScrollPane();
        jTable = new javax.swing.JTable();
        jScrollPane.setViewportView(jTable);
        getContentPane().add(jScrollPane);

        setPreferredSize(new Dimension(300,200));   
        setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);

        Object[][] data = {{"Item1", "Papaya", "Letus", "Cashew", "Pine"},
                             {"Item2", "Orange", "Carrot", "Pine nut", "Oak"},
                             {"Item3", "Apple", "Pepper", "Pistacho", "Cypress"}};
        Object[] headers = {"Item", "Fruit", "Vegetable", "Nuts", "Tree"};
        tableModel = new DefaultTableModel(data, headers);
        jTable.setModel(tableModel);

        jTable.setAutoCreateColumnsFromModel( false );
        for (int i=0; i<jTable.getColumnCount(); i++){
            jTable.getColumnModel().getColumn(i).setMinWidth(100);
        }
        jTable.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);

        jTable.setRowSorter(new TableRowSorter<DefaultTableModel>(tableModel));

        jTable.addPropertyChangeListener(new PropertyChangeListener() {
            public void propertyChange(PropertyChangeEvent e) {
                if ("selectionModel".equals(e.getPropertyName())) {
                    freezeTable.setSelectionModel(jTable.getSelectionModel());
                }

                if ("dataModel".equals(e.getPropertyName())) {
                    freezeTable.setModel(jTable.getModel());
                }
            }
        });

        freezeTable = new javax.swing.JTable();
        freezeTable.setAutoCreateColumnsFromModel(false);
        freezeTable.setModel(tableModel);
        freezeTable.setSelectionModel(jTable.getSelectionModel());
        freezeTable.setFocusable(false);

        for (int i = 0; i < fixedColumns; i++) {
            TableColumnModel colModel = jTable.getColumnModel();
            TableColumn column = colModel.getColumn(0);
            colModel.removeColumn(column);
            freezeTable.getColumnModel().addColumn(column);
        }

        freezeTable.setPreferredScrollableViewportSize(freezeTable.getPreferredSize());
        jScrollPane.setRowHeaderView(freezeTable);
        jScrollPane.setCorner(JScrollPane.UPPER_LEFT_CORNER, freezeTable.getTableHeader());

        jScrollPane.getRowHeader().addChangeListener(new ChangeListener() {
            public void stateChanged(ChangeEvent e) {
                //  Sync the scroll pane scrollbar with the row header
                JViewport viewport = (JViewport) e.getSource();
                jScrollPane.getVerticalScrollBar().setValue(viewport.getViewPosition().y);
            }
        });
        pack();
    }

    public static void main(String args[]) {
        java.awt.EventQueue.invokeLater(new Runnable() {
            public void run() {
                new TestClass().setVisible(true);
            }
        });
    }
}

将行排序器应用于两个表...

TableRowSorter<DefaultTableModel> sorter = new TableRowSorter<>(tableModel);
jTable.setRowSorter(sorter);
//...
freezeTable.setRowSorter(sorter);
