JTable支持点击Enter按键进行换列操作

     最近在做一个Java Swing的应用程序，使用到了JTable控件，需求就是当我点击Enter按键的时候，table能够换列，原先没有思路，然后再问答里提问了，有位小伙伴跟我说了用ActoinMap，非常感谢，现在问题解决了，和大家分享下，源码如下

 

import java.awt.BorderLayout;
import java.awt.event.ActionEvent;

import javax.swing.AbstractAction;
import javax.swing.ActionMap;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JTable;
import javax.swing.UIManager;
import javax.swing.table.DefaultTableModel;

public class JTableResponseEnterKey extends JFrame {

	private static final long serialVersionUID = 1L;

	private JPanel contentPane;
	private JTable table;

	public JTableResponseEnterKey() {
		init();
		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		setBounds(100, 100, 705, 502);
		setVisible(true);

	}

	public void init() {
		contentPane = new JPanel();
		contentPane.setLayout(new BorderLayout(0, 0));
		setContentPane(contentPane);
		table = new JTable();
		table.setModel(new DefaultTableModel(new Object[][] {
				{ "一", "二", "三" }, { "四", "五", "六" }, }, new String[] { "第一列", "第一列", "第一列" }));

		ActionMap am = (ActionMap) UIManager.get("Table.actionMap");
		am.put("selectNextRowCell", new AbstractAction() {
			private static final long serialVersionUID = 1L;

			@Override
			public void actionPerformed(ActionEvent e) {
				if(table.getEditingColumn() == -1){	//假如当前没有选中编辑列，默认第一行第一列
					table.editCellAt(0, 0);
				}else if (table.getEditingColumn() < table.getColumnCount() - 1) {
					System.out.println("focus下一列");
					table.editCellAt(table.getEditingRow(),table.getEditingColumn() + 1);
				} else {
					System.out.println("focus下一行");
					table.editCellAt(table.getEditingRow() + 1, 0);
				}
			}
		});
		table.setActionMap(am);

		contentPane.add(table, BorderLayout.CENTER);
	}

	public static void main(String[] args) {
		new JTableResponseEnterKey();
	}

}
