自动滚动主要注意三个变量:

1,要显示的滚动区域,

2,滚动时间,

3每次滚动的位移量

滚动效果主要是根据transition样式进行设置: transition: width 2s; 第一个参数是指方向,第二个是移动时长

再通过数据的需求设置每次需要移动的距离,js方法设置即可,可视区域外的元素遮盖(overflow:hidden)即可,代码如下:

<template>
  <div style="height:100%;width:100%">
    <div class="body" :style="view">
      <div class="scroll-content" :style="{top}" >
        <tr v-for="item in dutyRateData">
          <td>{{item.group}}</td>
          <td>{{item.bookNum}}</td>
          <td>{{item.sceneNum}}</td>
          <td>{{item.dutyRate}}</td>
        </tr>
      </div>
    </div>
  </div>
</template>
