v-for一个list，通过add方法添加list中的一个个体

<div id="app">

         <el-button type="primary" plain @click="addEl">添加</el-button>

        <el-row>
            <el-col :span="24" v-for="(list,index) in lists">
                <el-row :gutter="20" class="margins">
                    <el-col :span="2">
                        职员{{index+1}}名字
                    </el-col>
                    <el-col :span="6">
                        <el-input type="text" v-model="list.name">
                    </el-col>
                    <el-col :span="6">
                        <el-button type="danger" @click="del(index)">删除信息</el-button>
                    </el-col>
                </el-row>
            </el-col>
        </el-row>
    </div>
    <script>
        var vm = new Vue({

                },

            }
