rowData.add(row);

}

//初始化数据表格

tab = new JTable(rowData,columNames); 

tab.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);//

//初始化滚动面板

jsp = new JScrollPane(tab);

this.setTitle("报表显示");

this.setVisible(true);

this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

this.setBounds(100, 100, 700, 400);

this.getContentPane().add(jsp);

} catch (Exception e) {

// TODO: handle exception

e.printStackTrace();

}

}

public static void main(String[] args) {

Demo2 demo = new Demo2();

}

}
