非常简单的问题也记下来好了，以免再犯同样错，div 加滚动条
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>MyHtml.html</title>
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="this is my page">
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
<!--<link rel="stylesheet" type="text/css" href="./styles.css">-->
</head>
<div style="overflow-x: scroll; overflow-y: scroll; width:315px;height:365px;">
<table width="300" height="100" border="1">
<tr><td>行1</td></tr>
<tr><td>行2</td></tr>
<tr><td>行3</td></tr>
</table>
</div>
</body>
</html>
开始把宽和高加在table上了，给100了div的滚动条还是不出来，后来发现应该加在div上
