If your question is why it works with the first table, and not the
second, I do not have an answer. I would not expect it to work with
either, because 3 is the second dimension.
I verified that both work when I use the transpose of what ctload
returns.
I would guess that the init method looks for the dimension with length
3, while the setproperty method just assumes it is the first.
