Row Counts: 2ⁿ

The idea
A table for n distinct simple statements needs 2ⁿ rows — every combination of truth values, exactly once.
In practice
Two letters, four rows. Three letters, eight. Standard fill: halve the alternation each column.
Where people slip
The standard fill order isn't decoration. It guarantees no combination is missed or duplicated.
