固定页眉弹性表 - 页眉垂直对齐

Question

jsFiddle - https://jsfiddle.net/24by5tmv/1/

我有一个简单的弹性表格，它可以固定标题并滚动表格正文，但我想垂直对齐每个单元格内的内容（标题和正文）的中心/中间。

将单元格设置为vertical-align: middle; 通常可以解决问题，但似乎使用 flexbox 会阻止垂直对齐单元格内容。

我不怀疑我忽略了一些东西，而且可能是一些简单的东西，但是有没有人有任何解决这个问题的想法？

非常感谢:)

您也可以使th,td 元素弯曲并在其中应用对齐方式：

table.flex-table tr td,
table.flex-table tr th {
  display: flex;
  flex: 1;
  align-items:center;
  justify-content:center;
}

完整代码

.panel-body {
  height: 300px;
}

table {
  border-top: 1px solid black;    /* Just to Highlight Top of Table */
}
table thead tr {
  height: 5em;    /* Fixed Row Height */
}

/* Flex Table */
table.flex-table {
  display: flex;
  flex-direction: column;
  height: 100%;
}
table.flex-table thead,
table.flex-table tbody {
  display: block;
}
table.flex-table thead {
  margin-right: 0px;
}
table.flex-table tbody {
  flex: 1;
  overflow-y: scroll;
}
table.flex-table tr {
  width: 100%;
  display: flex;
}
table.flex-table tr td,
table.flex-table tr th {
  display: flex;
  flex: 1;
  align-items:center;
  justify-content:center;
}
