Ranking by multiple category

[Stan_Lego]

category	sub-category	time taken	rank
A	C10	3	1
A	C10	4	2
A	C20	2	1
A	C20	6	2
A	C20	9	3
B	C10	2	1
B	C10	3	2
B	C20	6	1
B	C20	9	2

so i would like to create ranking that ranks time taken based on the sub-category and that it repeats for each sub-category and each category. Can anyone help me on this as rankx seems to only be able to consider only 1 category and i am unable to make it repeat for each sub-category.

@Stan_Lego , Rank as a new column

rankx(filter(Table, [Category] = earlier([Category]) && [Sub Category] = earlier([Sub Category])  ), [time],,asc,dense)
