elementui表格嵌套表单

在处理表格表单的时候，通常会遇到校验表格里面的内容，可能很多人就直接盲写，如果实现的效果定制化没那么多，可以试一下封装，话不多说直接上代码

先看效果

tableForm.vue

<<template>
    <div>
    <e-button
      type="primary"
      v-if="!disabled"
      @click="handleAddColumn"

    ><el-form ref="formData" :model="formData">
      <el-table :data="formData[tableName]">

注意：表格表单最核心的就是校验表格里面填写内容，:prop="tableName + '.' + scope.$index + '.' + item.prop"这块拼接的地方不能出错

以上就是表格嵌套表单并触发校验的案例。
