css class 操作列 按钮 之间加 竖线 | class="your-handleBtn" :last-child::after


思路:botton 加一个class 每个右边加个竖线,最后一个不加。
用起来很方便


.your-handleBtn{
  position: relative;
  display: inline-block !important;
  padding: 4px 9px !important;
  border:0 !important;
}

.your-handleBtn::after {
  position: absolute;
  content: '';
  display: block;
  width: 1px;
  height: 16px;
  top: 8px;
  right: -1px;
  background: #E5E5E5;
}

.your-handleBtn:last-child::after {
  display: none;
}
