效果如图：

1.下载插件

npm install vue-seamless-scroll --save

 2.在main.js中引入注册

import scroll from 'vue-seamless-scroll'
Vue.use(scroll)

3.在页面中使用（写一个固定的表头 el-table:show-header="status" 设置为false,自带的表头不显示）

 <div class="table-box">
       //静态表头
      <div class="toptitle">
        <div class="item">序号</div>
        <div class="item">检测点</div>
        <div class="item">时间</div>
        <div class="item">识别项</div>
        <div class="item">结果</div>
      </div>
       //滚动组件
      <vue-seamless-scroll :data="tableData" :class-option="optionHover" class="seamless-warp">
        <el-table :data="tableData" @row-click="showRowDetail" style="width: 100%"  :show-header="status"
           :row-class-name="tableRowClassName">
          <el-table-column type="index" label="序号" width="50">
          </el-table-column>
          <el-table-column prop="siteName" label="检测点">
            <template slot-scope="scope">
              <span>{{ scope.row.siteName ? scope.row.siteName : '---' }}</span>
            </template>
          </el-table-column>
          <el-table-column prop="ts" label="时间">
            <template slot-scope="scope">
              <span>{{ scope.row.ts ? scope.row.ts : '---' }}</span>
            </template>
          </el-table-column>
          <el-table-column prop="fun" label="识别项">
            <template slot-scope="scope">
              <span>{{ scope.row.fun == "valve" ? '炉门' : scope.row.fun == "rod" ? '摆臂' : '---' }}</span>
            </template>
          </el-table-column>
          <el-table-column prop="err" label="结果">
            <template slot-scope="scope">
              <span>{{ scope.row.err === 0 ? '正常' : scope.row.err === 1 ? '异常' : '---' }}</span>
            </template>
          </el-table-column>
        </el-table>
      </vue-seamless-scroll>

    </div>

4.js配置滚动插件配置对象

 computed: {
    optionHover() {
      return {
        step: 1, // 数值越大速度滚动越快
        limitMoveNum: 2, // 开始无缝滚动的数据量 this.dataList.length
        hoverStop: true, // 是否开启鼠标悬停stop
        direction: 1, // 0向下 1向上 2向左 3向右
        openWatch: true, // 开启数据实时监控刷新dom
        singleHeight: 20, // 单步运动停止的高度(默认值0是无缝不停止的滚动) direction => 0/1
        singleWidth: 0, // 单步运动停止的宽度(默认值0是无缝不停止的滚动) direction => 2/3
        waitTime: 1000, // 单步运动停止的时间(默认值1000ms)
      };
    },
  }

3.效果图样式

<style lang="scss" scoped>
.right-box {
  height: 36%;

  .table-box {
    height: 85.2%;
    background: #051f51;
  }

}

.seamless-warp {
  height: 200px;
  overflow: hidden;
}

/deep/ .el-table {
  background: transparent !important;
}
//隔行换色
/deep/ .el-table .even-row td {
  background-color: #082959 !important;
  color: #47e2ff;
}

/deep/ .el-table .odd-row td {
  background-color: #051f51 !important;
  color: #47e2ff;
}

/deep/.el-table td,
/deep/.el-table th.is-leaf {
  border: none;
}

/deep/.el-table--border::after,
/deep/.el-table--group::after,
/deep/.el-table::before {
  background-color: transparent !important;
}

/deep/.el-table .cell {
  text-align: center;
}
//设置固定表头样式，保证滚动时候表头固定不动
.toptitle {
  width: 100%;
  display: flex;

  .item {
    width: 20%;
    text-align: center;
    color: #fff;
    background: #093376;
    padding: 10px;
  }
}
</style>
