grouping when value is an array

[jhaaken]

I have a column which is an array of values which I render in the table cell as csv format. When I group that column I want the values to be spread across to their proper group. Is this possible?

row with a single column of array values

row1 = ['a']
row2 = ['a', 'b']
row3 = ['a', 'b', 'c']
row4 = ['b']

what I get

> a (1)
> a, b (1)
> a, b, c (1)
> b (1)

what I want

> a (2)
> b (3)
> c (1)

Ok, I figured it out by adding a custom groupingFn to check if cell value was an array using the defaultGroupFn as a base and passing it into the instance of useTable. I did make wrap it in useCallback() vs useMemo() so I could pass parameters to it. I then also had to adjust my cell render to use the groupByVal vs the actual cell's value.
