I cannot easily compare data elements of comparative data. Here's
what I mean,

john smith observation 1 observation 2
weight 160 155
belt size 40 38
shoe size 12 11

bill jones observation 1 observation 2
weight 128 119
belt size 29 28
shoe size 8 9

mary Dee observation 1 observation 2
weight 120 129
belt size 25 26
shoe size 8 9

But, I have many rows of these comparative data, and I have many
subjects. I end up cutting and pasting each pair of cells so the look
like,
