在html想要实现九九乘法表的效果，有很多种方法，我们可以通过for循环的方式解决该需求，当然，我们也可以通过一种更加简洁明了的编码方式实现
关键代码：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>九九乘法表</title>
<style>
table {
width: 100%;
border-collapse: collapse;
}
td, th {
border: 1px solid #ddd;
padding: 8px;
text-align: center;
}
th {
background-color: #f2f2f2;
}
</style>
</head>
<body>
