JAVA修改、删除数据之后刷新JTable的方法

以下代码不完整，仅把关键的代码贴出来

String userTitle[] = {"ID","用户名","密码","邮箱","名字","等级"};

tab = new Object[userInfoNumber][6];

Iterator<User> iter = userList.iterator();

while(iter.hasNext()){

User user = iter.next();

tab[i][0] = user.getId();

tab[i][1] = user.getUserName();

tab[i][2] = user.getPwd();

tab[i][3] = user.getMail();

tab[i][4] = user.getName();

whatGrade = user.getGrade() == 1 ? "管理员" : "普通会员";

tab[i][5] = whatGrade;

i ++;

}

DefaultTableModel tableModel = new DefaultTableModel(tab,userTitle);

JTable table = new JTable(tableModel);

for(int j = 0;j < table.getRowCount();j ++){

//获得删除时选择的ID在JTABLE中的行号

if(Integer.parseInt(table.getValueAt(j, 0).toString()) == id){

int selIndex = j;

if( selIndex < 0 || selIndex >=table.getRowCount() ){

   return ;

}

//删除这一行

tableModel.removeRow(selIndex) ;

//刷新

tableModel.fireTableDataChanged();

break;

   }

}

如果是更新数据的话，只需

tableModel.fireTableDataChanged();
