vue3 数据可视化大屏 项目开发时，经常会遇到table效果，但是限于页面大小，table的数据并不能完全的显示出来，这就需要让table滚动起来，之前使用vue2已经实现过了类似的效果，vue table组件结合vue-seamless-scroll实现滚动，这次是使用的vue3组件变了所以从新记录一下。

安装依赖

组件使用了Vue3SeamlessScroll所以需要先安装一下依赖。

pnpm i Vue3SeamlessScroll

组件代码

<template>
  <div class="tableCom">
    <div class="tableHead">
      <div class="tableHeadItem" v-for="(item,index) in head" :key="index" :style="{flex:item.flex}">{{ item.title }}
      </div>
    </div>
    <Vue3SeamlessScroll :wheel="true" :hover="true" :list="list" class="tableBody">
      <div class="tableBody2" v-for="(item,index) in list" :key="index">
        <div class="tableBody2Item" style="flex: 1.5">
          <span class="top1" v-if="index==0">top1</span>
          <span class="top2" v-else-if="index==1">top2</span>
          <span class="top3" v-else>top{{ index + 1 }}</span>
        </div>
        <div class="tableBody2Item" style="flex: 1.5">
          电站1
