5.总体代码：

为了便于大家复制，下面给出完整的程序代码，如下：

package ArrayCreateTable;

import javax.swing.table.*;

import java.awt.BorderLayout;

import java.awt.GridLayout;

import javax.swing.*;

public class ArrayCreateTable extends JFrame {

private JTable table=null;

private JPanel jp=new JPanel();

private JTable getTable(){

if(table==null){

table=new JTable();

String[] columns={"ID","姓名","性别","邮箱","电话","备注"};

int[] columnWidth={50,40,30,60,70,70};

DefaultTableModel model=new DefaultTableModel(columns,8);

table.setModel(model);

TableColumnModel columnModel=table.getColumnModel();

int count=columnModel.getColumnCount();

for(int i=0;i

javax.swing.table.TableColumn column=columnModel.getColumn(i);

column.setPreferredWidth(columnWidth[i]);

}

}

return table;

}

private void showWindow(){

this.getTable();

JTableHeader  myt=table.getTableHeader();

jp.add(myt,BorderLayout.NORTH);

jp.add(table,BorderLayout.CENTER);

this.add(jp);

this.setTitle("表格实例");

this.setBounds(100, 100,330, 200);

this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

this.setVisible(true);

this.setResizable(false);

}

public static void main(String[] args) {

ArrayCreateTable aa=new ArrayCreateTable();

aa.showWindow();

}

}
