效果如图

原理是把数组拆成多个数组,十个一组

      <!-- 表格 -->
      <el-table
        slot="tablePage"
        ref="slantTable"
        :data="dataSourceList"
        tooltip-effect="dark"
        height="100%"
        style="width: 100%"
        :header-cell-style="{ background: '#f2f3f8', color: '#515a6e' }"
      >
        <el-table-column type="index" label="序号" width="50" align="center">
          <template slot-scope="scope">
            {{ 10 * (pageInfo.current - 1) + scope.$index + 1 }}    // 排序累加
          </template>
        </el-table-column>
      </el-table>
      <!-- 分页 -->
      <el-pagination
        slot="pageBox"
        background
        @current-change="handleCurrentChange"
        :current-page="pageInfo.current"
        layout="total, prev, pager, next"
        :total="pageInfo.total"
      >
      </el-pagination>

处理数据

          this.dataSource = res.data;
          this.pageInfo.total = res.data.length;
          this.dataSourceList = this.arrSlice(res.data, 10)[
            this.pageInfo.current - 1
          ]; // 使用配置好的方法进行数

methods里面处理数据

    arrSlice(arr, len) {
      let newArr = [];
      for (var i = 0; i < arr.length; i += len) {
        newArr.push(arr.slice(i, i + len));
      }
      return newArr;
    },

分页

    handleCurrentChange(val) {
      this.pageInfo.current = val;
      this.dataSourceList = this.arrSlice(this.dataSource, 10)[val - 1];
    },
