通常情况下，SO不适用于电子邮件请求，我们确实希望请求者做出一些努力。
这对那些知道的人来说是微不足道的。
请注意，如果您发现浏览器不能很好地解析日期字符串，则可能需要更改msSinceEpoch，因为only the ISO 8601 format (YYYY-MM-DDTHH:mm:ss.sssZ) is explicitly specified to be supported
该脚本位于页面头部的<script></script>标签中，即样式表中的CSS。

const msSinceEpoch = str => Date.parse(str); // returns an int 

window.addEventListener("DOMContentLoaded", () => { // on page load
  document.querySelectorAll(".stuff tbody tr").forEach(row => { // ignore the thead
    const dateCell1 = row.querySelector(".table-date_one"); 
    const dateCell2 = row.querySelector(".table-date_two"); 
    const date1 = msSinceEpoch(dateCell1.textContent);
    const date2 = msSinceEpoch(dateCell2.textContent);
    const greater = date2 > date1; // true or false
    row.classList.toggle("highlight", greater);     // set if greater
    dateCell2.classList.toggle("greater", greater); // set if greater
  });
});

.highlight {
  color: red;
}
.greater { font-weight: bold;}
