element table伪类显示白色问题

强制修改  第二个是子弹框类的样式没有加 !important 但实现了效果

.el-table__body tr.hover-row > td.el-table__cell,.el-table--enable-row-hover .el-table__body tr:hover>td{
  background-color:rgba(15, 61, 151, 0.8)!important;
}
.el-table--group::after, .el-table--border::after, .el-table::before {
    background-color: transparent;
}
