Java中JTable实现查找功能

原文地址：http://www.xiaoyuanbiji.top/714.html

class MyFrame extends JFrame {
	private static final long serialVersionUID = 1L;
	public MyFrame() {
		Toolkit toolkit = Toolkit.getDefaultToolkit();
		Dimension dimension = toolkit.getScreenSize();
		setSize((int) (dimension.width * 0.5), (int) (dimension.height * 0.5));
		// 设置窗体居中显示
		setLocationRelativeTo(null);
		setDefaultCloseOperation(EXIT_ON_CLOSE);

		
		JTable table = new JTable();
		//设置表格的数据模型
		DefaultTableModel model = (DefaultTableModel) table.getModel();
		//设置表头
		model.setColumnIdentifiers(new Object[] {"1","2"});
		table.setModel(model);
		//自动创建RowSorter
		table.setAutoCreateRowSorter(true);
		//添加一行内容
		model.addRow(new Object[] {"A","4"});
		model.addRow(new Object[] {"B","9"});
		model.addRow(new Object[] {"A","5"});
		JScrollPane pane = new JScrollPane();
		//将JTable添加到JScrollPane中
		pane.setViewportView(table);
		add(pane);
		setVisible(true);
		//这里是关键
		TableRowSorter sorter = new TableRowSorter(model);
		table.setRowSorter(sorter);
		//实现过滤，search为正则表达式，该方法支持参数为null和空字符串，因此不用对输入进行校验
		String search = "5";
		sorter.setRowFilter(RowFilter.regexFilter(search));
	}
