This is my first post

I was wondering if someone could help me with the following

Here are the results that I am looking for from the data below. - data
will be 50k+ rows long! and columns can all have numerical values

I have no problems with adding some concat columns if needed

#1 VENDOR (sales ranked descending) – from, a concat of Store & Dept &
Vendor
#2 VENDOR (sales ranked descending) – from, a concat of Dept & Vendor
#3 Rank of TOP 5 Vendors from Col B
#4 Rank of Bottom 5 Vendors from Col B
