First you'll have to say what kind of tables, since the code
for packing Paradox vs. dBASE tables is quite different in
each case (though some have written routines that identify
the file type, and procede from there).

Anyway, there are a number of places to go for the info:

-the Delphi Tech Info docs; one of the documents is devoted
to this subject.

-online examples at http://www.borland.com/devsupport/bde/

-search for past postings to this newsgroup at http://www.deja.com/
(this question and the answer have both been posted often)
