I used ordinal strings ("first", "second") instead ("The", "quick") to eliminate the need to scroll up to the table declaration to count which index is "fox" etc.
I added comments with outputs of Console.Write[Line]. Without the comment it seems that the Write[Lines] don't improve to the page and could be removed.
I used the existing snippet for table initialisation instead of an inline snipped (i.e. removed duplication).
