哪么可以在里面在在循环里加上条件for（int i= 0；i<10;i++）{行数 数据}如果你想一页显示10条记录 分很多页去显示，哪么你可以做个分页在jsp里设定 变量：一页显示的数量 和用数据得条数除以一页显示的条数算出一共需要几页。int count = 0;int onepagesize = 6;//一页显示的留言数量 默认是10int allmessage;//所有的留言数量int onepagecount;int messagecount = 1;//消息计数器int sumpage;//总页数if (stronepagesize != null) {onepagesize = integervalueof(stronepagesize); //获取一页显示的留言数}conn = dbconnectiongetconnection();ps = dbconnectiongetpreparedstatement(conn,select from message order by id);rs = psexecutequery();rslast();//将rs指针指向最后一行；allmessage = rsgetrow();//获得行号，也就留言总数数是一些代码得片段。仔细看看 肯定就明白了
看看下面的代码，应该对你有帮助：

这个是有jsp的实现的，应该可以满足你的要求。再给你个用JavaScript实现的。
<html>
<head>
<title>九九乘法表</title>
</head>
<body>
<script language="JavaScript">
for(i=1;i<=9;i++){
documentwrite("<br>");
for(j=1;j<=9;j++){
if(ji<10)
documentwrite(j+""+ i+"= "+ji+" " );
else
documentwrite(j+""+ i+"="+ji+" ");
}
}
documentwrite("<br>");
for(m=1;m<=9;m++){
documentwrite("<br>");
for(n=1;n<=m;n++){
if(nm<10)
documentwrite(n+""+ m+"= "+nm+" " );
else
documentwrite(n+""+ m+"="+nm+" ");
}
}
</script>
</body>
</html>
如果不满意，我还可以在修改一下呀!
