I want to split a cell which currently looks like this: 'Y: AM - N: PM'
horizontally. I dont think I will be doing any calculations on this cell but
I want to be able to instantly distinguish between the two so that the cell
in effect still looks like one cell but with a line in the middle and 'Y: AM'
in the top and 'N: PM' in the bottom section.

Does anyone know if this is this possible?
