vue2 + element-ui中的el-form和el-table嵌套，实现表格表单内容编辑 + 表格表单数据校验 + 动态增减表单项

vue2 + element-ui中的el-form和el-table嵌套，实现表格表单内容编辑 + 表格表单数据校验 + 动态增减表单项

结合element-ui框架，Form表单示例动态增减表单项，又结合网上资料查询，实现。

效果图：

实现

1.el-form封装的表单校验功能
2.el-form动态增减表单项时，除了增加删除 form 的字段，校验规则 rules 也需要一起增加删除
3.el-table-column prop属性，render-header 方法，slot插槽

代码：

<el-form
          ref="dataForm"
          :model="form"
          :rules="rulesForm"
          label-position="right"
          label-width="110px"
          class="chargeRulesForm"
      >
	<el-form-item label="规则配置">
       <el-table :data="form.pilePriceRuleItemVOS">
