在 CSS 中将 box-shadow 添加到 tbody 中?

Ale*_*uck 2 html css html-table

我正在尝试重新创建我在 Photoshop 模型中制作的这个材料设计表:

在此输入图像描述

除了阴影之外,我已经得到了我想要的一切。当我对 tbody 元素应用阴影时,它会在 Firefox 中显示,但不会在 Chrome 或 Edge 中显示。如果我也对其应用“display: block”样式,它也会显示。但是,这会删除默认的“display: table-row-group”样式,从而有效地破坏了表的结构。如何添加阴影而不影响布局的其余部分?

* {
  font-family: Roboto, Arial;
}

body {
  background: #f8f8f8;
}

table {
  border-collapse: collapse;
  width: 100%;
}

th {
  font-weight: normal;
  opacity: .7;
  text-align: left;
  padding-left: 20px;
  padding-bottom: 10px;
}

td {
  padding: 20px;
}

tbody tr:nth-child(even) {
  background: rgba(128,128,128,.05);
}

tbody {
  background: #fff;
  
  /* This doesn't work unless "display: block" is applied, which ruins the structure */
  box-shadow: 0 2px 5px 0 rgba(0,0,0,0.16),0 2px 10px 0 rgba(0,0,0,0.12);
  -moz-box-shadow: 0 2px 5px 0 rgba(0,0,0,0.16),0 2px 10px 0 rgba(0,0,0,0.12);
  -webkit-box-shadow: 0 2px 5px 0 rgba(0,0,0,0.16),0 2px 10px 0 rgba(0,0,0,0.12);
}

.grey {
  opacity: .5;
}

.green {
  color: #4caf50;

我在这个问题上花了几个小时,终于找到了一个不会破坏表格布局的可行解决方案。但现在我想起来,flexbox 可能会简单得多......

table {
  position: relative;
}

table:after {
  content: '';
  position: absolute;
  box-shadow: 0 2px 4px 0 rgba(37, 37, 37, 0.2); // your box-shadow
  left: 0;
  right: 0;
  top: 36px; // height of your table header
  bottom: 0;
  z-index: -1;
}
