I'd bet that it's not in fact solid wood. Euros do a lot of veneer
table
tops, especially the type you described. Since wood expands more
acrossed
the grain than with the grain, if it were solid wood it would either
pull
or push itself apart or dip or bow in the middle.

Have posted an image to a.b.p.w showing the two possible grain
orientation,
each with what would happen if the wood expanded or contracted - more
acrossed
the grain and less with the grain. If it's solid wood, it will expand
and contract as humidity and temperature changes in its environment

I'd pass on this one.
