 style="width: 100%">
 <el-table-column
  label="日期"
  width="180">
  <template scope="scope">
  <span v-if="!scope.row.editFlag">{{ scope.row.name }}</span>
  <span v-if="scope.row.editFlag" class="cell-edit-input"><el-input v-model="inputColumn1" placeholder="请输入内容"></el-input></span>
  <span v-if="!scope.row.editFlag" style="margin-left:10px;" class="cell-icon" @click="handleEdit(scope.row)"> <i class="el-icon-edit"></i> </span>
  <span v-if="scope.row.editFlag" style="margin-left:10px;" class="cell-icon" @click="handleSave(scope.row)"> <i class="el-icon-document"></i> </span>
  </template>
 </el-table-column>
 </el-table>
</template>
<script>
export default{

 data(){

  },
  ],
  inputColumn1:""//第一列的输入框
 }
 },
 methods:{
 handleEdit:function(row){
  //遍历数组改变editeFlag
 },
 handleSave:function(row){
  //保存数据，向后台取数据
 },
 handleMouseEnter:function(row, column, cell, event){
  cell.children[0].children[1].style.color="black";

</script>
<style>
.cell-edit-input .el-input, .el-input__inner {
