4.模板位置及内容
<!DOCTYPE html>
<html xmlns:th="http://www.w3.org/1999/xhtml">
<head>
<meta charset="utf-8">
<title>表格</title>
</head>
<body>
<table border="1">
<tr>
<td><h4>邮件主题</h4></td>
<td colspan="5">
<a th:href="@{http://ip/}" th:text="${mailSubject}"> </a>
</td>
</tr>
<tr>
<td><h4>通知时间</h4></td>
<td colspan="5" th:text="${noticeTime}"></td>
</tr>
<tr>
<td><h4>通知类型</h4></td>
<td colspan="3">
<span th:text="${noticeText}" th:style="${noticeText == '正常通知' ? 'color: green;' : 'color: red;' }"></span>
</td>
<td><h4>任务编号</h4></td>
<td colspan="3">

</td>
</tr>
<tr>
<td><h4>姓名</h4></td>
<td colspan="3" th:text="${name}">

</table>
</body>
</html>
<style>
table, th, td {
border: 1px solid black;
border-collapse: collapse;
}
div {
margin-top:10px;
}
.icon {
