请问如何自动隐藏JTABLE里面空白的行和列？

public class Part2 extends JFrame implements TableModelListener{
	
	private DefaultTableModel tableModel;
	private JTable tableView;
	private String[] columnNames = {"A","B","C","D","E"};
	private String[][] records;
	
	private JButton insertRow, deleteRow, save;
	private JPanel top,tablePane;
	

	public static void main(String[] args){
		EventQueue.invokeLater(new Runnable() {
			public void run() {

					Part2 frame = new Part2();
					frame.setVisible(true);
				} catch (Exception e) {
					e.printStackTrace();
				}
			}
		});
	}
	public Part2() {
		records = new String[20][5];
		
		//Initialise the JButtons
		insertRow = new JButton("Insert Row");
		deleteRow = new JButton("Delete Row");
		save = new JButton("Save");
		
		//Initialise the top panel
		top = new JPanel();
		top.add(insertRow);
		top.add(deleteRow);
		top.add(save);
		add("North",top);
		
		records[0][0]="1";
		records[0][2]="2";
		/*
		 * Create a JTable view and set its model. The JTable component is
		 * implicitly registered as a listener of tableModel.
		 */
		tableModel = new DefaultTableModel(records, columnNames);
		tableView = new JTable(tableModel);
		
		

		// Make each cell selectable.
		tableView.setRowSelectionAllowed(false);
		/*
		 * Register listeners (views) with the model.
		 */
		tableModel.addTableModelListener(this);		

		/* Setup the GUI. */
		setupPane(tableView);	

		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		setBounds(100, 100, 900, 300);
	}
	
	private void setupPane(JTable tableView) {
		// Create a ScrollPane to hold the JTable
		JScrollPane scrollPane = new JScrollPane(tableView);		
		scrollPane.setBorder(BorderFactory.createEmptyBorder(5,5,5,5));	
		add(scrollPane); // Add the ScrollPane to JFrame
	}
	public void tableChanged(TableModelEvent e) {}
}

代码如上
代码会产生一个JTABLE，第一行会有两个格有数据，其余全部是空白的，请问该如何自动检测并隐藏那些空白的行和列但是保持tablemodel不变呢

隐藏基本不可能，因为绘制的时候就决定了你有那么多东西，你只能填充空字符串之类的数据。
另外tablemodel的话你可以分开操作，在初始化table之前先拷贝出来一份，然后再修改原有的tablemodel

[ryantao2010]

int rowsNum = calLinesNum("data.txt");
		int colsNum = calTokensNum("data.txt");
		records = new String[rowsNum][colsNum];
		
		String[] columnNamesView = getColumnNamesView(columnNames,colsNum);

思路大概是这样吧
