Inside the predicate the context node is a table attribute.
Attributes do not have attributes, so @table evaluates to an empty
node-set.  Try:
///@table[not(. = preceding::node()/@table)]

Also, don't do this for large documents, unless you have plenty of
time ;-).  There are better methods - for example look up Muenchian
grouping in the FAQ.
