官网原话
Form 组件提供了表单验证的功能，只需要通过 rules 属性传入约定的验证规则，并将 Form-Item 的 prop 属性设置为需校验的字段名即可。
表单
el-form表单必备以下三个属性：
:model="ruleForm" 绑定的数据内容
:rules="rules" 动态绑定的rules，表单验证规则
ref="ruleForm" 绑定的对象
template模块
其实问题关键就在于如何给el-form-item动态绑定prop
:prop="'tableData.' + scope.$index + '.字段名'"
<template>

补充知识：element-ui 跟form 和table 动态表单校验，数组的深层次校验
首先数据结构是这样的
let cchiCombineBill = [
{
infoId: '1716',
clinicCchiCombineName: '星期四',
clinicCchiCombineId: '3',
serviceCount: '1',
cchis: [
{
cchiCode: 'CAAJ1000'
},
{
cchiCode: 'CAAJ1400'
}
]
},
{
infoId: '1816',
clinicCchiCombineName: '星期五',
clinicCchiCombineId: '3',
serviceCount: '1',
cchis: [
{
cchiCode: 'CAAJ1000'
},
{
cchiCode: 'CAAJ1400'
}
]
}
]
<template>

</p>
<el-table :data="item.cchis" border style="width: 100%;">

之前一直是数组结合table 一层的校验，琢磨了很久才终于领悟 element-ui 的 form表单校验的精髓所在，
那就是 :prop 一定是遍历的数组'cchiCombineBill.' 加上（cchiCombineBill，index）中 的index，再加上具体要校验的字段。
以上这篇vue element table中自定义一些input的验证操作就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持。
