Citing a verbatim copy of a table?
There are two separate issues here, which must be dealt with individually:


From a perspective of copyright law, you must make sure that you can obtain the right to reproduce the table at all.
From a perspective of scientific ethics, quoting a table is exactly like quoting a passage of text or quoting a figure. You simply need to make absolutely certain that it is clear that the table is being reproduced from somebody else's publication, and why it is more useful to the reader to reproduce the table rather than to provide a shorter summary of its contents (e.g., if you will be discussing elements of the table in detail).


I would recommend stating that the table is a reproduction in two different places:


In the caption of the table itself (e.g., "Classes of frobozinator, reproduced from [Cite]")
In the text where you first refer to the table (e.g., "Let us now turn to a more detailed discussion of frobozinators, as guided by the taxonomy developed in [cite].  For ease of reference, the table of classes from [cite] is reproduced in Table 5.")
