使用二维数组构造JTable

package _15;

import javax.swing.JFrame;

import javax.swing.JScrollPane;

import javax.swing.JTable;

public class SimpleTable extends JFrame {

public SimpleTable() {

// 定义表头

String[] columnNames = { "First Name", "Last Name", "Sport", "#of Years", "Vegetarian" };

// 定义表格数据（二维数组）

Object[][] data = {

{ "Kathy", "Smith", "Snowboarding", new Integer(5), new Boolean(false) },

{ "John", "Doe", "Rowing", new Integer(3), new Boolean(true) },

{ "Sue", "Black", "Knitting", new Integer(2), new Boolean(false) },

{ "Jane", "White", "Speed reading", new Integer(20), new Boolean(true) },

{ "Joe", "Brown", "Pool", new Integer(10), new Boolean(false) }

};

// 创建JTable并关联数据和表头

JTable table = new JTable(data, columnNames);

// 放入滚动面板（支持表格滚动）

JScrollPane scrollPane = new JScrollPane(table);

add(scrollPane);

}

public static void main(String[] args) {

SimpleTable frame = new SimpleTable();

frame.setSize(300, 300);

frame.setTitle("Simple Table");

frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

frame.setVisible(true);

}

}
