Hi @jherring - I do not have anything close to a definitive answer for this, but allow me to point you in a few possible directions based on some Canvas Community questions/discussions that have popped up in the past regarding this. Since you are comfortable using tables, depending on what you want IN those table cells, you may want to consider using a series of drop-down menus. I can't find a good example of this off-hand, other than a good illustration provided here: How can I make a table with drop-downs in Quizzes LTI? Please do not let the topic of the new Quizzes LTI throw you off. @rebecca_haukaas is asking if something that she did on the current quiz engine will work with the new one under development. You likely are using the "old" (meaning current) quiz engine rather than the still-in-Beta Quizzes LTI. Rebecca's screen capture on that question, however, shows what I have in mind as a possible solution for you.
You may also want to check the following two resources:
Both of those deal with numeric-type answers, though, and I'm not sure if that's what you have in mind based on your example. (I suspect not; at least not for all of them.)
Perhaps some of this information will be of help, Jeff. I am sure other brighter minds in the Community may have some of their own suggestions.
