     3Table objects, roughly speaking, are a set of columns and lines (data sets).
     4
     5The user can define columns where the data is entered manually, but also columns can be added that are automatically filled in with data from another table by matching.
     6
     7In order to explain '''matching''', let me give the following example:
     8   Let there be two tables A and B, with columns A1, A2 and B1. Now a user could add a new column (called B2) to table B, using data from table A.
     9   Say that B1 contains GIS-IDs, and A1 and A2 GIS-IDs and their respective geographic coordinates.
     10   Then the user could fill the new column B2 with those values of A2, where A1 is equal to the given B1.
     11   This is the simplest possible scenario for matching.
