vue element-ui 可编辑表格

轻量级
提供 slot-scope=“scope” 字段名 会提取 prop prop 没有 就需要提供 change-filed-name=“name” name 就是 字段名

   <el-table-column prop="number" label="数字" width="180">
        <template slot-scope="scope">
          <edit-input-number :scope="scope"/>
        </template>
      </el-table-column>

editInput.vue

<template>
  <div @dblclick="dbClickMethod" style="height:36px;">
    <!--  可编写 表格 原理
       1. 提供 行数据
       2. 是否可以开启 isEdit
       3. 双击编写
       4. 回车 或 失去 焦点 @blur -->
    <span v-if="!isShowInput" style="display: block;width: 100%;height: 100%;padding-top: 6px">{{
        (scope.row)[filedName]
      }}</span>

    <el-input size="medium" :style="{height:height,width:width}" @keyup.enter.native="isShowInput=false"
              v-model=" (scope.row)[filedName]" :placeholder="placeholder" v-show="isShowInput" @change="change"

设置为全局 组件

index.js

import editInput from "./editInput";
import editInputNumber from "./editInputNumber";


const customTemplate = {
  install: function (Vue) {
    Vue.component('edit-input', editInput) //注册全局组件
    Vue.component('edit-input-number', editInputNumber) //注册全局组件

  }
}

export default customTemplate

main.js

import customTemplate from "./views/customTemplate"
Vue.use(customTemplate);
