> If {{--incremental}} is specified in Beeline, rows are meant to be printed out immediately. However, if {{TableOutputFormat}} is used with this option the formatting can look really off.
> The reason is that {{IncrementalRows}} does not do a global calculation of the optimal width size for {{TableOutputFormat}} (it can't because it only sees one row at a time). The output of {{BufferedRows}} looks much better because it can do this global calculation.
> If {{--incremental}} is used, and {{TableOutputFormat}} is used, the width should be re-calculated every "x" rows ("x" can be configurable and by default it can be 1000).
