Review Comment:
I would like to have checked that tabletExtent.prevEndRow() is less than
deleteRange.prevEndRow() here, howerver that is cumbersome to do with the
possibility of nulls. Thinking the equals checks w/ the other checks in the if
achieves this, but the intent is not as clear in the code.
