element-ui 解决 table 里包含表单验证的问题！

实际项目中的场景，需要在table里做表单的验证，如图效果：

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'"

详见代码：

<template>
    <div v-bgb-block>
        <div style="margin-top:10px;">
            <el-form :rules="model.rules" :model="model"  ref="form">
                <!-- 表布局 -->
                <el-table
                border
                :data="model.tableData"
                style="width: 100%;"
                :default-sort = "{prop: 'date', order: 'descending'}"
                >
                <el-table-column
                    width="100px"
                    label="要求批次">
                    <template slot-scope="scope">
                            <el-form-item :prop="'tableData.' + scope.$index + '.input'" :rules='model.rules.name'>
                                <el-input style="width:80px"  v-model="scope.row.input" ></el-input>
                            </el-form-item>
                    </template>
                </el-table-column>
                <el-table-column
                    width="180px"

                            </el-form-item>

                </el-table-column>
                <el-table-column
