I'm trying to use a VBA script that will compare two tables and notify the user whether or not they are identical. Specifically, the two tables are identical when they contain the exact same number of rows and data within those rows - the number of columns will not vary.

I think I know how I could do this by looping through each row individually and comparing rows, so there is no need to provide me with a solution doing that. What I'm wanting to find out is if there is a quicker way that could just compare both tables as entire ListObjects. Thanks!

Test for Multiple Conditions in IF?
Use AND(test, test, test, test) or OR(test, test, test, ...) as the logical_test argument of IF.
