Find difference between the values of the current and previous row for every field

[jjiangDSAU]

I have a table with the following format:

Field1	Field2	Field3
1	1	10
2	3	8
3	7	5
4	15	1

I want to overwrite every value with the difference between that value and the value in the previous row, for every field. (For an arbitrary number of fields.)

Thereby creating the following table: 

Field1	Field2	Field3
0	0	0
1	2	-2
1	4	-3
1	8	-4

I assume the key is the multi-row formula tool but I'm afraid the needed logic is a bit beyond me. 

Would appreciate any help. Thanks a lot.

You can use transpose and multi row logic combination to calculate the difference for each column. I have attached the workflow, let me know if you are good with it

Works like a charm, thank you Prakhar.
