ant-design-vue vue2 a-table行间隔颜色控制，奇偶行颜色

项目需求

如标题所说，table的行颜色一样不明显，需要行间隔颜色明显，逻辑是通过奇偶行数来单独设置颜色 。

<a-table>要单独设置颜色实现需要css穿透方式实现，而且要指定特定class名字否则会影响所有table

效果： 

重点代码:穿透更新css

• 单独设置css名字：.emptablerow , 后面跟着的是ant-design-vue配置2n（代表所有偶数行）行css:设置颜色#a2fca2

.emptablerow ::v-deep .ant-table-tbody tr:nth-child(2n)
{
  background-color:#a2fca2;
}

这个是写在模版.vue文件最后 <style>里面

• 然后是在<a-table>外层控件里的class写

实现源码：
