React+Antd-ProTable

 后面部分的表头由接口返回，数据结构：

 //处理：数据请求
  const handleRequest = async (params) => {
    const otherParams = formTrimParams(formRef.current.getFieldsValue())
    const res = await getUserList({
      page: params.current,
      row: params.pageSize,
      ...otherParams
    });

    if (res && res.code === 200) {
      let max=0
      let dataList = [];
      res.data.list.forEach((item) => {
        if (item.dq.length > max) {
          max = item.dq.length;
          dataList = item.dq;
        }
        return dataList;
      });
      const addColumns = dataList.map(item => {
        return {
          children:[{title:item.day,children:[{dataIndex: item.data_class,title:item.data_class}]}],
          title: item.week,
          search: false,
        }
      });
      let newColumns = [...columns, ...addColumns];

      setColumns(newColumns);
      // console.log(newColumns, 'newColumns')
      const newList = res.data.list.length ? res.data.list.reduce((total, pre) => {
        let obj = pre.dq.reduce((prev, next) => {
          prev[next.data_class] = next.qty
          return prev
        }, {})
        total.push({ ...pre, ...obj })
        return total;
      }, []) : []
      // console.log(newList)
      return {
        data: newList,
        // data: res.data.list,
        total: res.data.total,
        success: true,
        pageSize: res.data.row,
        current: res.data.page,
      }
    } else {
      message.error(res.msg ? res.msg : '获取数据失败');
      return {
        data: [],
        total: 0,
        success: true
      }
    }
  }
