Summary
This change allows tablify to work on non-rectangular arrays without generating errors. For example, when outputting parsed CSV files with trailing empty cells omitted/removed by trimmed whitespace.
Motivation
Removes the need for looping over and modifying the input array reference several times to prepare it for tablify by the user.
References
This implements the line-count-even implementation suggested by sri and tests provided by lindleyw in #1132.
