我有24条数据，想要快速整合成4条数据，如下图：
希望大佬们能提供一些思路，不想写那么多 if 条件判断。
这是返回的6周的全部数据的规则：
以 louceng_category 的不同来显示每一周的 数量（wk_order_qty）、环比（order_qty_chain）
期望返回格式如下：
[
{
louceng_category: 'A',
wk1_order_qty:1,
wk1_order_qty_chain: '-',
wk2_order_qty: 2,
wk2_order_qty_chain: '-',
wk3_order_qty: 3,
wk3_order_qty_chain: '-',
wk4_order_qty: 4,
wk4_order_qty_chain: '-',
wk5_order_qty: 5,
wk5_order_qty_chain: '-',
wk6_order_qty: 6,
wk6_order_qty_chain: '-',
},
{
louceng_category: 'B',
wk1_order_qty:1,
wk1_order_qty_chain: '-',
wk2_order_qty: 2,
wk2_order_qty_chain: '-',
wk3_order_qty: 3,
wk3_order_qty_chain: '-',
wk4_order_qty: 4,
wk4_order_qty_chain: '-',
wk5_order_qty: 5,
wk5_order_qty_chain: '-',
wk6_order_qty: 6,
wk6_order_qty_chain: '-',
},
...
]以下是后端接口返回的原始数据

reduce，单纯的使用Map数据结构做了一下分类，其实用数组也可以，但是Map比较方便，以下是面向过程的业务代码：先做一下排序，也不知道你的周次数据是否后端返回前有没有做过排序，所以一并排序了，也可以在最后一步排序，但其实差不太多。
然后是数据分类:
获得到的数据结果为：
最后是组装成你需求的 tableData 格式
获得到的最终数据结果为：
