如何设置列的Jtable名称

JTable table = new JTable();

TableColumnModel columnModel = table.getColumnModel();

TableColumn column = columnModel.getColumn(columnIndex);
column.setHeaderValue(columnName);

table.getTableHeader().repaint();

import javax.swing.*;
import javax.swing.table.*;

public class JTableColumnNameExample {
    public static void main(String[] args) {
        // 创建表格数据
        Object[][] data = {
            {"John", "Doe", 30},
            {"Jane", "Smith", 25},
            {"Bob", "Johnson", 35}
        };

        // 创建表格列名
        String[] columnNames = {"First Name", "Last Name", "Age"};

        // 创建 JTable 对象
        JTable table = new JTable(data, columnNames);

        // 设置列名称
        TableColumnModel columnModel = table.getColumnModel();
        TableColumn column = columnModel.getColumn(0);
        column.setHeaderValue("First");
        column = columnModel.getColumn(1);
        column.setHeaderValue("Last");
        column = columnModel.getColumn(2);
        column.setHeaderValue("Age");

        // 更新表格显示
        table.getTableHeader().repaint();

        // 创建 JFrame 并添加表格
        JFrame frame = new JFrame();
        frame.add(new JScrollPane(table));
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.pack();
        frame.setVisible(true);
    }
}
