tbl = cat (dim, tbl1, tbl2, …) concatenates the input tables along dimension dim, which must be either 1 or 2, since a table always has exactly two dimensions.

cat (1, …) concatenates vertically and is equivalent to vertcat, whereas cat (2, …) concatenates horizontally and is equivalent to horzcat. The same requirements on variable names, row names and size apply, and a 0x0 operand that is not a character array takes no part in the concatenation.
