Assume I have two lists: A[1,1]={1,2} and A[2,1]={3,4}.

When I create a table

Table[A[i,j],{i,1,2},{j,1,1}] 

I get

{{{1,2}},{{3,4}}}

How can I have a result {{1,2},{3,4}}? Of course, using Table or some other function.

Table[A[i, 1], {i, 1, 2}]

{{1, 2}, {3, 4}}

Alternatively,

A[#, 1] & /@ {1, 2}

{{1, 2}, {3, 4}}

Also

Flatten[Table[A[i, j], {i, 1, 2}, {j, 1, 1}], 1]

{{1, 2}, {3, 4}}

You could also use Tuples:

Tuples[A[{1,2}, {1}]]

{{1, 2}, {3, 4}}
