jquery - 如何在没有任何插件的情况下卡住表头并在垂直滚动时显示？

Question

我用过很多插件，比如 freezeHeaders、stickytableHeaders、floatThead，但没有任何帮助。

在我的元素中，页眉和页脚是不变的。它是动态的。这是一个巨大的元素。在我当前的 jsp 中，我将显示包含标题和动态数据的标题和表格。

我需要在页眉和页脚之间卡住标题。

任何人都可以给出解决这个问题的确切想法。

请。

请看下面的例子:

.fixed_headers {
  width: 750px;
  table-layout: fixed;
  border-collapse: collapse;
}
.fixed_headers th {
  text-decoration: underline;
}
.fixed_headers th,
.fixed_headers td {
  padding: 5px;
  text-align: left;
}
.fixed_headers td:nth-child(1),
.fixed_headers th:nth-child(1) {
  min-width: 200px;
}
.fixed_headers td:nth-child(2),
.fixed_headers th:nth-child(2) {
  min-width: 200px;
}
.fixed_headers td:nth-child(3),
.fixed_headers th:nth-child(3) {
  width: 350px;
}
.fixed_headers thead {
  background-color: #333;
  color: #FDFDFD;
}
.fixed_headers thead tr {
  display: block;
  position: relative;
}
.fixed_headers tbody {
  display: block;
  overflow: auto;
  width: 100%;
  height: 300px;
}
.fixed_headers tbody tr:nth-child(even) {
  background-color: #DDD;
}
.old_ie_wrapper {
  height: 300px;
  width: 750px;
  overflow-x: hidden;
  overflow-y: auto;
}
.old_ie_wrapper tbody {
  height: auto;
}

<table class="fixed_headers">
