java table_Java中Table的应用

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"},

{"沙和尚","男","56","103","挑担子","取经团队"},

{"白龙马","男","123","104","驼唐僧","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

rowData =(Vector) data.get(i);

for(int j=0;j

field = (String) rowData.get(j);

ss[i][j] = field;

}

}

}

public static void main(String[] args) {

new TableTest();

}

}

效果图如下：

如需要对表格的更多操作可参考以下两个例子：
