vue+Element中table表格实现可编辑(select下拉框)

<el-table :data="processNodelist" style="width: 100%" border stripe>
 <el-table-column type="index" label="序号" width="50"></el-table-column>
 <el-table-column prop="nodename" label="流程节点名称"></el-table-column>
 <el-table-column label="处理人名称">
 <template slot-scope="scope">
 <el-select v-model="scope.row.proJbruserValue" @focus="getDatalist(scope.row)" placeholder="请选择" filterable allow-create>
 <el-option v-for="item in projectJbrUserlist " :key="item.id" :label="item.username" :value="item.id">
 </el-option>
 </el-select>
 </template>
 </el-table-column>
</el-table>
<el-button @click="submitConfigHandle" type="primary" size="mini" icon="el-icon-upload">提交配置</el-button>
