ElementUI table表格组件实现双击编辑单元格失去焦点还原，支持多单元格

在使用ElementUI table表格组件时有时需要双击单元格显示编辑状态，失去焦点时还原表格显示。

实现思路：

• 在数据中增加isFocus:false.控制是否显示
• 在table中用@cell-dblclick双击方法

先看效果：

上源码：在表格模板中用scope.row.isFocus && focusLabelName=='姓名1控制多个单元格显示

<el-table :data="tableData" border stripe style="width: 100%"  @cell-dblclick="tabClick">
    <el-table-column prop="date" label="Product Name" width="180"></el-table-column>
    
    <el-table-column prop="address" label="地址"></el-table-column>

    <el-table-column prop="price" label="姓名1"  width="180">
        <template slot-scope="scope">
            <el-input v-if="scope.row.isFocus && focusLabelName=='姓名1'" v-focus size="small" v-model="scope.row.price" @change="changeTrafOrigTaxAmount(scope.row)" @blur="blurInput(scope.row)"></el-input>
            <span v-else>{{scope.row.price}}</span>
        </template>
    </el-table-column>

    <el-table-column prop="price" label="姓名2"  width="180">
        <template slot-scope="scope">
            <el-input v-if="scope.row.isFocus && focusLabelName=='姓名2'" v-focus size="small" v-model="scope.row.price2" @change="changeTrafOrigTaxAmount(scope.row)" @blur="blurInput(scope.row)"></el-input>
            <span v-else>{{scope.row.price2}}</span>
        </template>
    </el-table-column>
</el-table>

方法：

data: function () {
        return {
            tableData: [{

            }],
            focusLabelName:''
        }
    },
    methods: {
        tabClick(row, column, cell, event)
        {
            console.log(row, column, cell);
            row.isFocus = true;
            this.focusLabelName = column.label;
            
        },
        blurInput(row)
        {
            row.isFocus = false
        }
    }
