新计算 Table 以每小时拆分持续时间

Question

我有一份包含大量任务的数据表，它们的 start/end 时间、持续时间和开始日期。

Task	Start Time	End Time	Duration	Start Day
Task1	21:00	22:15	1:15	Monday
Task1	21:20	23:30	2:10	Monday
Task2	23:00	23:20	0:20	Tuesday

我想做的是将这些数据放入一个新的计算 table 中，它将拆分每个任务并为每小时花费的分钟数绘制一个新行，具体取决于持续时间。例如：

Task	Hour	Mins in Hour	Start Day
Task1	21	60	Monday
Task1	22	15	Monday
Task1	21	40	Monday
Task1	22	60	Monday
Task1	23	30	Monday
Task2	23	20	Tuesday

我运气不好，有人可以帮忙吗？

可以用 PQ 完成

let
