html - 悬停时显示表格行边框

Question

我使用 div 表，但是当我在行上设置 hover 时，它不起作用，标题/.thead 没问题，但在 < strong>.tbody 它不起作用，悬停仅显示 左边框、右边框 和 下边框 ，我是吗忘记了什么？怎么解决呢？这是我的代码:

.divTable {
  display: table;
  width: 100%;
  border-collapse: collapse;
  border-spacing: 0 5px;
}

.divTable .tr {
  display: table-row;
}

.divTable .thead {
  display: table-header-group;
}

.divTable .td,
.th {
  display: table-cell;
  padding: 3px 10px;
}

.divTable .thead {
  display: table-header-group;
  font-weight: bold;
}

.divTable .tfoot {
  display: table-footer-group;
  font-weight: bold;
}

.divTable .tbody {
  display: table-row-group;
}

.divTable {
  font-size: 12px;
  cursor: default;
  width: 100%;
}

.divTable .th,
.divTable .td {
  padding: 4px 6px;
}

.divTable .tr {
  border: 1px solid white;
  height: 26px;
}

.divTable .tr:hover {
  background-color: rgba(162, 216, 242, 0.14);
  border: 1px solid rgba(124, 204, 243, 0.58);
  border-top: 1px solid rgba(124, 204, 243, 0.58);
  height: 26px;
}

<div class="divTable">
  <div class="thead">
    <div class="tr">
      <div class="th">Filename</div>
      <div class="th">Type</div>
      <div class="th">Size</div>
    </div>
  </div>
  <div class="tbody">
    <div class="tr">
      <div class="td">Why Cannot Work.jpg</div>
      <div class="td">Image</div>
      <div class="td">12.1 KB</div>
    </div>
    <div class="tr">
      <div class="td">Lorem Ipsum.jpg</div>
      <div class="td">Image</div>
      <div class="td">12.1 KB</div>
    </div>
    <div class="tr">
      <div class="td">Dolor Sir Amet.jpg</div>
      <div class="td">Image</div>
      <div class="td">12.1 KB</div>
    </div>
  </div>
</div>

Answer 1

我相信这就是 border-collapse 的工作原理，因为上部单元格的底部边框折叠到底部单元格的顶部边框中。

解决此问题的方法之一是在 .td 元素上指定边框。因此，您可以为所有 .td 单元格提供顶部和底部边框，并分别为 :first-child 和 :last-child 分别。这将有效地实现你想要的。

.divTable .tr:hover .td {
  border-top: 1px solid rgba(124, 204, 243, 0.58);
  border-bottom: 1px solid rgba(124, 204, 243, 0.58);
}

.divTable .tr:hover .td:first-child {
  border-left: 1px solid rgba(124, 204, 243, 0.58);
}

.divTable .tr:hover .td:last-child {
  border-right: 1px solid rgba(124, 204, 243, 0.58);
}

下面的代码片段展示了它的外观:

.divTable {
  display: table;
  width: 100%;
  border-collapse: collapse;
  border-spacing: 0 5px;
}

.divTable .tr {
  display: table-row;
}

.divTable .thead {
  display: table-header-group;
}

.divTable .td,
.th {
  display: table-cell;
  padding: 3px 10px;
}

.divTable .thead {
  display: table-header-group;
  font-weight: bold;
}

.divTable .tfoot {
  display: table-footer-group;
  font-weight: bold;
}

.divTable .tbody {
  display: table-row-group;
}

.divTable {
  font-size: 12px;
  cursor: default;
  width: 100%;
}

.divTable .th,
.divTable .td {
  padding: 4px 6px;
}

.divTable .tr {
  border: 1px solid white;
  height: 26px;
}

.divTable .tr:hover {
  background-color: rgba(162, 216, 242, 0.14);
  border: 1px solid rgba(124, 204, 243, 0.58);
  height: 26px;
}

.divTable .tr:hover .td {
  border-top: 1px solid rgba(124, 204, 243, 0.58);
  border-bottom: 1px solid rgba(124, 204, 243, 0.58);
}

.divTable .tr:hover .td:first-child {
  border-left: 1px solid rgba(124, 204, 243, 0.58);
}
.divTable .tr:hover .td:last-child {
  border-right: 1px solid rgba(124, 204, 243, 0.58);
}

<div class="divTable">
  <div class="thead">
    <div class="tr">
      <div class="th">Filename</div>
      <div class="th">Type</div>
