In order to answer a question on the weekend, I wrote a bunch of code and the functions were basically implemented, but I felt that the structure was too poor and I didn’t think much about it. Not pretty at all
The code copy is as follows:
<!DOCTYPE HTML>
<HTML>
<head>
<TITLE>The document title</TITLE>
<meta charset=utf-8>
<script src="lib/jquery-1.8.1.min.js" type="text/javascript"></script>
<style type="text/css">
table{
border-spacing: 0;
}
td{
height: 50px;
width: 50px;
border-spacing: 0;
}
.hidden{
display: none;
}
</style>
</head>
<body>
<table>
<tr id ="r1">
<td></td>

<tr id ="r2">
