Gregory,

Table[i*j, {i, 8}, {j, 8}] returns a list with dimensions {8, 8}.  But
if the expression inside Table returns a single-element list, then the
table will have dimensions {8, 8, 1}.  Example: Table[{i*j}, {i, 8}, {j,
8}].  So you could try using

Table[
First[(complicated expression that returns a single element list)],
{i, 8}, {j, 8}
]
