I think what you would have to do is "merge" the 5-7 cells for the week heading. Because Excel uses unique identifiers for each cell (a1, b4, etc...), you can't really "split" a cell. Merging the heading cells should give the desired look though, One big cell one top with 5-7 individual cells underneath it.
Yep, that's the way to do it very simple and straightforward.
