1.autoflow属性，如果元素内容的长宽超出元素本身的长宽则会出现滚动条

<HTML> 
<HEAD> 
<TITLE>测试表格内的滚动条</TITLE> 
</HEAD> 
<BODY> 
<div id="wins" 
        style="position:absolute;height:200;width:200;overflow:auto;background:#EEEEEE;"> 
        <p>pppppppppppppppppppppppppppppppppppppppppppppppppp </p> 
        <p>pppppppppppppppppppppppppppppppppppppppppppppppppp </p> 
        <p>ppppppppppppppppppppppppp </p> 
        <p>ppppppppppppppppppppppppp </p> 
        <p>ppppppppppppppppppppppppp </p> 
        <p>ppppppppppppppppppppppppp </p> 
        <p>ppppppppppppppppppppppppp </p> 
        <p>ppppppppppppppppppppppppp </p> 
        <p>ppppppppppppppppppppppppp </p> 
        <p>ppppppppppppppppppppppppp </p> 
        <p>ppppppppppppppppppppppppp </p> 
        <p>ppppppppppppppppppppppppp </p> 
      </div>
</BODY> 
</HTML>

效果如下

2.选座位页面

<html>
<head>
 <meta charset="utf-8"> 
 <title>座位</title>
 <meta name="viewport"
 content="width=device-width,minimum-scale=1.0,maximum-scale=1.0,user-scalable=no">
 <link rel="stylesheet" href="http://cdn.static.runoob./libs/bootstrap/3.3.7/css/bootstrap.min.css">
 <script src="http://cdn.static.runoob./libs/jquery/2.1.1/jquery.min.js"></script>
 <script src="http://cdn.static.runoob./libs/bootstrap/3.3.7/js/bootstrap.min.js"></script>
 <style type="text/css">
      table tr td{
        padding: 5px;
      }
     </style>
      </head>
   <script>
  function createTable(){
var DivW=600;
var DivH=400;
var length=30;
var height=$("#h").val()/1;
var width=$("#w").val()/1;
var TableW=width(length+3);
var TableH=height(length+3);
$(".main").empty();
$(".main").width(TableW).height(TableH);
for(var a=0;a<height+1;a++){
 var str="<tr>";
 for(var b=0;b<width+1;b++){
  if(a==0&&b>0){
   str+='<td height="30px" width="30px">'+b+'</td>';
  }
  if(b==0&&a>0){
     str+='<td height="30px" width="30px">'+a+'</td>';
  }
  if(b>0&&a>0){
   str+='<td height="30px" width="30px" ><img src="img/2.png" width="30px" height="30px" /></td>';
  }
  
  if(a==0&&b==0){
    str+='<td height="30px" width="30px"></td>';
  }
 }
 str+="</tr>";
 $(".main").append(str);
}
  }
   </script>
<body>
<!-- 按钮触发模态框 -->
<button class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal" onclick="createTable()">

</button>
<input type="text" id="h" />排<input type="text" id="w" />座
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
