Java创建表格实例详解 原创

JTable(Object[][] rowDate,Object[] columnNames)

public class ExampleFrame_01 extends JFrame{
	public static void main(String[] args) {
		ExampleFrame_01 frame = new ExampleFrame_01();
		frame.setVisible(true);
	}
	public ExampleFrame_01() {
		super();
		setTitle("创建可以滚动的表格");
		setBounds(100,100,240,150);
		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		String[] columnNames = {"A","B"};    //定义表格列明数组
		//定义表格数据数组
		String[][] tableValues = {{"A1","B1"},{"A2","B2"},{"A3","B3"},
				{"A4","B4"},{"A5","B5"},{"A5","B5"},{"A5","B5"},{"A5","B5"},
				{"A5","B5"},{"A5","B5"},{"A5","B5"},{"A5","B5"},{"A5","B5"},
				{"A5","B5"},{"A5","B5"}};
		//创建指定列明和数据的表格
		JTable table = new JTable(tableValues,columnNames);
		//创建显示表格的滚动面板
		JScrollPane scrollPane = new JScrollPane(table);
		//将滚动面板添加到边界布局的中间
		getContentPane().add(scrollPane, BorderLayout.CENTER);
	}
	
}

JTable(Vector rowData.Vector columnNames)

public class ExampleFrame_02 extends JFrame{
	public static void main(String[] args) {
		 ExampleFrame_02 frame = new ExampleFrame_02();
		 frame.setVisible(true);
	}
	public ExampleFrame_02() {
		super();
		setTitle("创建不可滚动的表格");
		setBounds(100,100,240,150);
		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		Vector<String>columnNameV = new Vector<>();
		columnNameV.add("A");
		columnNameV.add("B");
		Vector<Vector<String>>tableValueV = new Vector<>();
		for(int row = 1;row<6;row++) {
			Vector<String>rowV = new Vector<>();
			rowV.add("A"+row);
			rowV.add("B"+row);
			tableValueV.add(rowV);
		}
		//创建指定表格列名和表格数据的表格
		JTable table = new JTable(tableValueV,columnNameV);
		//将表格添加到边界布局的中间
		getContentPane().add(table,BorderLayout.CENTER);
		JTableHeader tableHeader = table.getTableHeader();
		getContentPane().add(tableHeader,BorderLayout.NORTH);
