主要功能 :

1 , 一个表格 , 单元格内容是循环渲染的 , 点击每个单元格弹出一个输入框 , 编辑内容 

2 , 点击按钮添加行 , 点击序号删除行 

刚开始想用插件写的 ,网上找了半天,  研究好久搞不出来需要的效果 , 最后还是自己用table标签手写实现的 

<template>
  <div>
       <table class="tb1">
          <tr class="th">
            <td></td>
            <td>工作事项</td>
            <td>工作内容</td>
            <td>备注</td>
          </tr>
          <tr v-for="(item,index) in list" :key="index">
            <td @click="del(index)">{{index+1}}</td>
            <td>
              <input type="text" v-model="item.item" @click="modifyItem(item,index)">
            </td>
            <td>
              <input type="text" v-model="item.content" @click="modifyContent(item,index)">
            </td>
            <td>
              <input type="text" v-model="item.remark" @click="modifyRemark(item,index)">
            </td>
          </tr>
      </table>

        <van-button type="info" size="small" @click="addRow" class="addBtn" v-if="this.$store.state.isHeadShow">+ 添加行
          (点序号删除行)
        </van-button>

        <van-button type="info" size="small" class="btn" @click="submit" >提交
        </van-button>
