I am going a little crazy with alignment in the tabular environment.
In the following code I would like both the top-left cell 'Green Die', and the last cell in the 2nd row '6' to be aligned vertically.
I know the alignment issues with the cell '6' have to do with it being the last column, because if I make it the second to last column it is aligned in the middle.
Thanks in advance for any and all help!
