java表格添加按钮

在 Java 中，可以使用 JTable 类来创建表格。要在表格中添加按钮，需要使用一个称为表格渲染器 (table renderer) 的组件。

下面是一个示例代码，可以帮助你在表格中添加按钮：

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.table.AbstractTableModel;
import javax.swing.table.TableCellRenderer;
import java.awt.Component;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

public class TableButtonExample {
    public static void main(String[] args) {
        JFrame frame = new JFrame();
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        Object[][] data = {
            {"John", "Doe", new JButton("Click me")},
            {"Jane", "Doe", new JButton("Click me")},
        };
        String[] columnNames = {"First Name", "Last Name", "Button"};

        JTable table = new JTable(new AbstractTableModel() {
            @Override
            public int getRowCount() {
                return data.length;
            }

            @Override
            public int getColumnCount() {
                return columnNames.length;
            }

            @Override
            public Object getValueAt(int rowIndex, int columnIndex) {
                return data[rowIndex][columnIndex];
            }

            @Override
            public String getColumnName(int column) {
                return columnNames[column];
            }

            @Override
            public boolean isCellEditable(int rowIndex, int columnIndex) {
                return columnIndex == 2;
            }
        });

        table.getColumn("Button").setCellRenderer(new TableCellRenderer() {
            @Override
            public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {
                JButton button = (JButton) value;
                button.addActionListener(new ActionListener() {
                    @Override
                    public void actionPerformed(ActionEvent e) {
                        System.out.println("Button clicked for row " + row);
                    }
                });
                return button;
            }
        });

        frame.add(new JScrollPane(table));
        frame.pack();
        frame.setVisible(true);
    }
}

在上面的代码中，我们使用了 AbstractTableModel 类来创建一个表格模
