Thanks Glenn. I think what she is looking for is a way to have a single question, where different versions of that question might have varying numbers of variables and operators, so that the number of rows and columns depends on random variables.
But it sounds like what you might be saying is that for a given seed, you can put all the answer evaluators into an array, and then pass that array to data tables? Possibly that could work.
Yes, the number of rows and columns of the table can be variable depending on the random parameters. Arrays can be dynamically created in numerous ways. You can push or unshift elements in loops, or just assign to a particular index (even an index that doesn't already exist in the array). You can even have a variable number of answer rules. You will probably need additional arrays to contain answer rules in that case.
