It has at least two meanings:

1.) All (better) soundcards have sample rom on board (many cycles of a
waveform like piano). This rom is called wavetable.  Beeing rom, you
can't change it. The piano sample sounds like piano, that's it.

2.) The PPG and Waldorf Wave and Microwave (and also Korg Wavestation I
think) stuff uses a rom/ram of single cycle waves and a wavetable to
index into it. That means: the wavetable gives the order in which the
single cycle waves are interpolated, one after another. Simple
example:  A wavetable with two entrys (one for a sine as first wave and
one for a saw) will interpolate between sine and saw.  Etc. The user
can controll the direction and speed of this scanning through the
table. This gives the specific sound to this breed of synths. You can
do a lot of strange things with the wavetables, create your own single
cycle waves, create rythm patterns (some waves, then silence, them
waves again etc.), try to convert spoken words or a drumloop into a
sequence of single cycle waves , etc etc.

Some people sometimes uses the word wavetable for the set of single cycle
waves as well, this makes it a bit confusing.

All to my best knowledge and understanding.
