动静表头的写法有很多种,前端要依据后端返回的数据格式来进行调整。明天给大家展现一种只有值,没有属性的写法

<el-table max-height="600" border :data="bodyData">
   <el-table-column  v-for="(item,index) in Header" :label="item" :key="index" show-overflow-tooltip align="center" 
        :min-width="index === 0 ?'120':''" :fixed="index === 0" v-if="Header.length && Header.length>0">
        <template slot-scope="scope">
              <el-input v-if="bodyData[scope.$index].Row[index] && JSON.stringify(bodyData[scope.$index].Row[index]).indexOf('{')>-1" 
                v-model="bodyData[scope.$index].Row[index].Reason" @blur="saveData(bodyData[scope.$index].Row[index])"></el-input>
              <span v-else>{{bodyData[scope.$index].Row[index]}}</span>
        </template>
    </el-table-column>
