The example in this article describes the method of realizing table highlighting with JS CSS. Share it with everyone for your reference. The details are as follows:

Here we use JavaScript CSS to realize the table highlighting function, which is actually similar to the effect of changing the color of alternate rows. The explanation is different, but this effect is triggered when the mouse is moved up and ends when the mouse is moved out.

The operation effect is as shown below:

The specific code is as follows:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>高亮的表格</title>
<meta http-equiv="content-type"
 content="text/html; charset=iso-8859-1" />
<style>
p, td, th {
  font: 0.8em Arial, Helvetica, sans-serif;
}
.datatable {
  border: 1px solid #D6DDE6;
  border-collapse: collapse;
  width: 80%;
}
.datatable td {
  border: 1px solid #D6DDE6;  
  padding: 4px;
}
.datatable th {
  border: 1px solid #828282;
  background-color: #BCBCBC;
  font-weight: bold;
  text-align: left;
  padding-left: 4px;
}
.datatable caption {
  font: bold 0.9em Arial, Helvetica, sans-serif;
  color: #33517A;
  text-align: left;
  padding-top: 3px;
  padding-bottom: 8px;
}
.datatable tr:hover, .datatable tr.hilite {
  background-color: #DFE7F2;
  color: #000000;
}
</style>
</head>
<body>
<table summary="List of new students 2003" class="datatable">
 <caption>Student List</caption>
 <tr>
 <th scope="col">Student Name</th>
 <th scope="col">Date of Birth</th>
 <th scope="col">Class</th>
 <th scope="col">ID</th>
 </tr>
 <tr>
 <td>Joe Bloggs</td>
 <td>27/08/1997</td>
 <td>Mrs Jones</td>
 <td>12009</td>
 </tr>
 <tr>
 <td>William Smith</td>
 <td>20/07/1997</td>
 <td>Mrs Jones</td>
 <td>12010</td>
 </tr>
 <tr>
 <td>Jane Toad</td>
 <td>21/07/1997</td>
 <td>Mrs Jones </td>
 <td>12030</td>
 </tr>
 <tr>
 <td>Amanda Williams</td>
 <td>19/03/1997</td>
 <td>Mrs Edwards</td>
 <td>12021</td>
 </tr>
</table>
<script type="text/javascript">
var rows = document.getElementsByTagName('tr');
for (var i = 0; i < rows.length; i++) {
  rows[i].onmouseover = function() {
    this.className += ' hilite';
  }
  rows[i].onmouseout = function() {
    this.className = this.className.replace('hilite', '');
  }
}
</script>
</body>
</html>
