使用示例：

            layout=false;                   //不使用表格布局，大家可以把这句注释掉看结果有何不同$name=$form->form_text("userid","userid","用户名","userid");$passwd=$form->form_passwd("passwd","passwd","密码","passwd");$submit=$form->form_button("","submit","submit","登录");$form_item=array($name,$passwd,$submit);$form->CreateForm($form_item);?>
