flyingsky 人气:0

最近在做可编辑特定列的单元格的elementUI table，看了N多的开源、文章，找到一个很优雅的实现方式，分享给大家。
PS:单元格可编辑的table，用英文搜索：Inline editable table with ElementUI 会得到高质量结果。

先上效果：

APP.vue：

<template>
 <div id="app">
   <div style="margin-bottom: 30px">
    <el-switch
      style="display: block"
      v-model="editModeEnabled"
      active-color="#13ce66"
      inactive-color="#ff4949"
      active-text="Edit enabled"
      inactive-text="Edit disabled">
     </el-switch>
   </div>
    <el-table
   :data="gridData"
   style="width: 100%">
   <el-table-column
    label="Name"
    min-width="180">
    <editable-cell slot-scope="{row}"
            :can-edit="editModeEnabled"
            v-model="row.name">
     <span slot="content">{{row.name}}</span>
    </editable-cell>
   </el-table-column>

   <el-table-column
    min-wwidth="150"
    label="Gender">

     <editable-cell 
     slot-scope="{row}" 
     editable-component="el-select"
     :can-edit="editModeEnabled"
     close-event="change"
     v-model="row.gender">
     
     <el-tag size="medium" 
         :type="row.gender === 'M' ? 'primary' : 'danger'" 
         slot="content">
         {{row.gender === 'M' ? 'Male': 'Female'}}
