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
