    Difference that it minus a variable of specific item


      I am looking to calculate a difference in the same column


      Like the sample below,  every difference is that it minus  the variable which contains 'A' at the same date.


      For example,  at date of 2016/1/1, the difference of "B-A"  is 1-1=0


      Does it have any method or function solving this problem?
