1，制作一张商品信息表,内容自定,要求用到行与列的合并
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>商品信息表</title>
<style>
table{
border: blue 2px solid;
color: black;
box-sizing: border-box;
box-shadow: 1px 1px 1px black;
width: 800px;
margin: 20px auto;
border-collapse: collapse;
}
table caption{
font-size: 2rem;
margin: 20px auto;
}
th,td{
border: 1px blue solid;
text-align: center;
padding: 10px;
}
</style>
</head>
<body>
<table>
<!--表格标题-->

2，使用<div><span><p><ul>...等标签来制作一张课程表
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>课程表</title>

}
section > ul >li {
display: table-cell;
border: 1px black solid;
padding:10px;

margin-top: -150px;
margin-left: -150px;
}
</style>
</head>
<body>
<div class="login">
<h3>用户登录</h3>
<p>
<label for="username">账号:</label>
<input type="text" name="username" id="username" placeholder="请输入注册账号">
