You can also set the amount of times to be equal to the array.width (or height etc.), so that if you change the size of the array you don't have to worry about your code later.
Yeah it'd be nice to see more support for tables in general. I see 2 options for the future, either:
♥ support CSVs properly so it's easier to use external editors
♥ or make more features for the Data editors in C3 so it's user friendly, moving closer to google sheets or excel in (e.g. sorting, moving rows/colums around, selecting multiple cells etc.).
