关于el-table中的el-form-item的表单校验，以及只校验部分（el-table中的）表单

一些说明：table中的数据data，必须要在form对象下，其他的参考下面的代码

下面是我项目中的一段代码：

<template>
    <el-form ref="tableForm" size="mini" :model="form" :rules="rules" label-width="120px">
        <el-row :gutter="18">
            <el-col :span="8">
                <el-form-item label="学生姓名：" prop="studentName">
                    <el-input disabled v-model="form.studentName"></el-input>
                </el-form-item>
            </el-col>
            <el-col :span="8">
                <el-form-item label="学生编号：" prop="studentNumber">
                    <el-input disabled v-model="form.studentNumber"></el-input>
                </el-form-item>
            </el-col>
            <el-col :span="8">
                <el-form-item label="年级：" prop="grade">
                    <el-input disabled v-model="form.grade"></el-input>
                </el-form-item>
            </el-col>
        </el-row>
        <el-row :gutter="18">
