AFAIK, the standard way to deal with a table where you have vertical  
lines that occur in some rows but not others is to use the  
\multicolumn command:

1) Define, as usual, the general layout of your table in the argument  
to the tabular environment
2) Override, as needed, for each appropriate entry. The \multicolumn  
command can not only define an entry that spans several columns, but  
also define an entry that spans a single cell but with a different  
alignment and/or vertical line specification.

Here is a quick and ugly example:

A & B & C\
D & \multicolumn{1}{c}{E} & F

In this example, there will be no vertical bar between the E and the F.
Of course, also the opposite effect (i.e. adding a vertical bar where  
one was not present in the template) can be just as easily achieved.
