我正在尝试添加内联链接(# 链接到 HTML 正文内的内联表)，通过它我可以在我的电子邮件中导航。
我将 javax.mail API 与 text/html 一起使用。
问题是链接在 outlook 等电子邮件客户端中打开时不起作用。
如果邮件是在浏览器中打开的(通过电子邮件客户端中的“在浏览器中查看选项”)，那么链接就可以正常工作。
请协助解决这个问题(我怎样才能在邮件客户端中拥有有效的内联链接)。 下面是我用来发送邮件的类。

最佳答案
按照 Aaron 指出的链接，我将详细信息表包含在一个命名的 anchor 标记中。
它已经在 Gmail 和 Outlook 2016 客户端上进行了测试，并且按预期工作。
现在builddataTables方法实现如下。
private static void builddataTables(List<LocalDate> dateList) {
dateList.forEach(date -> {
message.append("<a name=\"")
.append(date.toEpochDay())
.append("\" id=\"")
.append(date.toEpochDay())
.append("\"><table border=\"0\" cellpadding=\"0\" cellspacing=\"0\" style=\"width:500px;background-color: #cedbf3;border: 1px solid rgba(19, 14, 14, 0.56);padding:15px;\"><tr><td colspan=\"2\" style=\"background-color: #5ab4ff;color:#ffffff;line-height:100%;font-family:Helvetica,Arial,sans-serif;font-size:20px;font-weight:400;margin-bottom:5px;text-align:center;\">")
.append(date.format(DateTimeFormatter.ofPattern("cccc, dd MMMM yyyy")))
.append("</td></tr><tr><td style=\"width:30%;\">Key Dat1</td><td style=\"width:70%;\">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Praesent ac mi eu lorem sagittis lacinia vel ac metus</td></tr><tr><td>Key Data2</td><td>Cras lobortis consectetur mi a porttitor. Vestibulum blandit urna et elit sollicitudin</td></tr></table></a>");
});
}
