I need a filter which will show all rows n and n+1, if and only if, in row n,
A=1 and B=1, and in row n+1, A=0, B=2 and C=4; or, in row n, A=0, B=1 and
C=4, and in row n+1, A=1 and B=2. In other words, whether or not a row is to
be displayed depends not only on what is in the row but also on what is in
the preceding row or the following row. Can you tell me how to do this?
Thanks.
