<span style="font-size:14px;">import java.util.Vector;
    import javax.swing.JFrame;
    import javax.swing.JLabel;
    import javax.swing.JScrollPane;
    import javax.swing.JTable;
    import javax.swing.table.DefaultTableCellRenderer;
    import javax.swing.table.DefaultTableModel;
    
    public class TableTest extends JFrame{
    	
    	private JTable table;
    	private DefaultTableModel defaultTableModel = null;
    	private JScrollPane scrollPane;	
    	String Names[] = {"姓名", "性别","年龄","电话","特长","所属"};
    	Object[][] playerInfo = {
    			{"唐僧","男","28","100","念经","取经团队"},
    			{"孙悟空","男","600","101","打妖怪","取经团队"},
    			{"猪八戒","男","37","102","散伙","取经团队"},

    	};
    	private String ss[][];
    	
    	public TableTest() {
    		setTitle("表格测试");
    		setSize(500, 300);
    		setLocation(500, 200);
    		scrollPane = new JScrollPane();
    		scrollPane.setSize(300, 200);
    		
    		//创建一个只有表头的表格模型
    		defaultTableModel  = new DefaultTableModel( null,Names);
    		
    		//将playerInfo中非空元素插入表中
    		for(Object[] x:playerInfo){
    			if(x[0]!=null){
    				defaultTableModel.addRow(x);
    			}
    		}
    		
    		table = new JTable(defaultTableModel);
    		
    		//设置单元格中的文字居中 非表头单元格
    		DefaultTableCellRenderer   r   =   new   DefaultTableCellRenderer();   
    		r.setHorizontalAlignment(JLabel.CENTER);   
    		table.setDefaultRenderer(Object.class, r);
    		
    		scrollPane.setViewportView(table);	
    		add(scrollPane);
    		
    		setDefaultCloseOperation(DISPOSE_ON_CLOSE);
    		setVisible(true);
    		
    		/* //获取表格中的信息 
    		 * 
    		 * Vector data = defaultTableModel.getDataVector();
    		 * VectorToString(data);
    		 * 
    		 */
    	}
    	//将二维矢量数组转化成二维字符串数组 存储在数组ss中
    	public void VectorToString(Vector data){
    		Vector rowData;
    		ss = new String[10][3];
    		String field="";
    		for(int i = 0; i<data.size();i++){
    			rowData =(Vector) data.get(i);
    			for(int j=0;j<rowData.size();j++){
    				field = (String) rowData.get(j);
    				ss[i][j] = field;
    			}			
    		}	
    	}
    	
    	public static void main(String[] args) {
    		new TableTest();
    	}
    
    }</span>
