【记录】el-table前端做分页

    async showDia() {
      //加载列表
      if (this.configData.showPager) {
        this.pageList = this.listData.filter(
          (item, index) =>
            index < this.currentPage * this.pageSize &&
            index >= this.pageSize * (this.currentPage - 1)
        );
        this.total = this.listData.length;
      }
    },

    handleCurrentChange(val) {
      this.currentPage = val;
      this.showDia();
    },

el-table里： :data="showPager ? pageList : listData"

@current-change="handleCurrentChange"
