The periodic table isn't covered by copyright anyway. Most of our [[en:List of ...]] articles are similarly free; there is no copyright on information, only creative work. (IANAL, and it'd be interesting to ask one just how far that goes.)
The table itself, no. But the particular table in Wikipedia has different colors for the series, a particular selection of which series to have, and different colors for the different states of each element - all that is creative work and is under copyright.
And a chemistry textbook without its own periodic table is very strange - just copy the darn thing Karl. :)
