具有固定标题且在正文上没有滚动的引导表

Question

我正在尝试以自定义方式创建表格组件，我将表格 <thead> 固定，<tbody> 可滚动而无需正文滚动。

1. 问题是我不知道如何为保持表格的div.content-table 设置高度，以便始终保持相同的高度尺寸但不大于屏幕尺寸，所以我无法添加px 或其他类型的固定大小。

2. 我不知道为什么位置固定对<thead> 不起作用：|

Answer 2

1。不大于屏幕尺寸

您可以为此使用vw,vh 单位。

1vh = 1% * screenHeight
1vw = 1% * screenWidth

所以你的情况

max-height = calc(100vh - 200px);
max-width = 100vw;

2。为什么位置固定不起作用

如果你使用

thead{
  position:fixed;
}

thead 将与tbody 分开工作，我认为 css 在position:fixed 元素上单独计算。
