Simply put, the table comparison is broken down to the comparison of the cell values of each cell position.

So you convert the two tables to the shape of ([row], [col], [value]), and compare the value for each pair of ([row], [col]).

Here is a sample workflow.

The first container is to create two tables with 1000 rows x 1000 cols, with only 1 cell is updated for test.

It should work for larger tables, but the performance depends on the memory resources, of course.

If it takes too long to run the workflow, you may need to split the table.

The second container is to compare the two tables.

If the value fields you compare are [String] fields, you may replace the expression in the filter tool as below:

REGEX_Match([Table1],[Table2],0)

(Because "=" operator cannot be used to compare strings with Case-Sensitive.)

It might be worth then doing some corrections to the ones it lists, re running it, and getting the list down bit by bit
