Mr.Eric Rimbey
I have noticed my mistake in the expression of b2={{Range[1,1]},{Range[2,2]},{Range[3,3]}}.
The correct is b2={Range[1,1],Range[2,2],Range[3,3]}:
b1 = {{1}, {2}, {3}}
b2 = {Range[1, 1], Range[2, 2], Range[3, 3]}
I beg your pardon for my mistake.
Thank you for your pointing out.
Mr.Gianluca Gorni
I can not have got hints for "Grid" from the helpDocs. Now, I have found that "Grid" can be used in my old Mathematica. For a long time,when I used boxes, I almost have used them with DisplayForm to show forms.
Troubles in such low level commands of old version that bother me may unavoidable as you say.
Thank you for advice to the point.
