dev类似于excel的数据编辑

其实这个不是我最后的结果，只是中间demo，因为我的场景数据量很大，2w左右，有数据合并，我更倾向于el-table是实现，但不想el-input一直显示，想用if-else 去做隐藏，但是用type=textarea发现高度适配有点问题，其中做了两种实验：
（1）失去焦点和获取焦点获取容器的高度再赋值给 textarea
（2）textarea点位设置 position: absolute设置显示和隐藏样式，但是同样发现需要很多歌el-input做显示隐藏，但是我不想这么处理。
（3）用dev去实现el-table，用flex 或grid 布局去实现
以下为dev用flex去实现的方法
<template>
  <div class="page">
    <div class="table table-input-box">
      <div
        style="flex: 1"
        v-for="(item, index) in tableData"
        :key="index"
        class="textarea-item"
      >
        <div class="textarea-row">
          <div
            style="flex: 1"
            @click.prevent="inputBlurHandler($event, item)"
            class="column-item item1"
          >
            <el-input
              class="item__input"
              v-model="tableData[index].date"
              type="textarea"
              resize="none"
              placeholder="请输入内容"
              autosize
            ></el-input>
          </div>
          <div
            style="flex: 1"
            @click.prevent="inputBlurHandler($event, item)"
            class="column-item item2"
          >
            <el-input
              class="item__input"
              v-model="tableData[index].name"
              type="textarea"
              resize="none"
              placeholder="请输入内容"
