While most natural tables command can be embedded within other command 
the cells have to see the end command.

I guess this shouldn't be a problem for your case because something 
simpler can be used to create your desired layout but you have to 
provide more information:

1. Are there blocks side by side or do you stack them only vertically?

2. Do you need a frame around each block?

3. Are (small) gaps between the blocks allowed?
