Hello,
Since you already know the size of the table, it would be best to use 2D array, and index it to the correct size at the begining of your code. Then, after each test, use the Replace Array Subset to replace the appropriate row with the corresponding data.
Using File I/O after each test would add too much overhead.
Please find the attached example. I hope this is what you were looking for.
