表格操作问题

[cexo821]

以下代码是把指定区域内容复制到指定区域,我现在要完成的是,在一个表格中选中某一区域,复制该区域内容,然后再选中某一起始格,将复制内容粘贴进对应格中,如果选中的是多格,那粘贴进的也是多格

不知道该怎么把选中区域的内容复制到剪切板,然后还原到相应区域,查了半天没找到相关东西

package com.sun.java.swing;

import java.applet.Applet;
import java.awt.*;
import java.awt.event.*;
import java.awt.datatransfer.*;

public class ClipboardTest extends Applet implements ClipboardOwner {
	private Clipboard clipboard;

	private TextField copyFrom;

	private TextArea copyTo;

	private Button copy, paste;

	public void init() {
		// Obtain a reference to the system clipboard
		clipboard = getToolkit().getSystemClipboard();

		copyFrom = new TextField(20);
		copyTo = new TextArea(3, 20);
		copy = new Button("Copy To System Clipboard");
		paste = new Button("Paste From System Clipboard");

		add(copyFrom);
		add(copy);
		add(paste);
		add(copyTo);

		copy.addActionListener(new CopyListener());
		paste.addActionListener(new PasteListener());
	}

	class CopyListener implements ActionListener {
		public void actionPerformed(ActionEvent event) {
			// Wrap the data in a transferable object
			StringSelection contents = new StringSelection(copyFrom.getText());

			// Place the transferable onto the clipboard
			clipboard.setContents(contents, ClipboardTest.this);
		}
	}

	class PasteListener implements ActionListener {
		public void actionPerformed(ActionEvent event) {
			Transferable contents = clipboard.getContents(this);

			// Determine if data is available in string flavor
			if (contents != null
					&& contents.isDataFlavorSupported(DataFlavor.stringFlavor)) {
				try {
					String string;
					// Have contents cough up string
					string = (String) contents
							.getTransferData(DataFlavor.stringFlavor);
					copyTo.append(string);
				} catch (Exception e) {
					e.printStackTrace();
				}
			}
		}
	}

	public void lostOwnership(Clipboard clip, Transferable transferable) {
		System.out.println("Lost ownership");
	}
}

对了,要补充一句的是,JAVA自带Ctrl+C和Ctrl+V,是可以达到上面说的目的的,我是想菜单栏加上这几个功能,然后实现

我现在想实现Excle的功能,这方面的开方还不是很熟,达人们给点相关资料,不胜感激
