Compare Datatables - Matching Rows and Columns by Id

Question

I am comparing two datables and I get a 2 Datatable i need to match Columns and Row by D_ID and find the difference between the two values (columns are of string type)
I want to loop through table1 D_ID and find the same in table2 and then loop through column (match)and find the difference

Table 1

D_ID	Split	Value_1	Value_2	Value_3
N6K_12	Str	1.503	9.5E-03	-0.48
N6K_13	Ref	1.680	6.5E-03	-0.63
N6K_14	St	1.690	3.3E-03	-0.43
N6K_15	Ref	1.903	4.5E-03	-0.83

 table 2 - column D_ID is not in same order as table1 

D_ID	Value_2	Value_1	Value_3
N6K_14	3.503	2.5E-03	-3.48
N6K_13	5.680	2.5E-03	-1.63
N6K_15	4.690	5.3E-03	-0.63
N6K_12	8.903	5.5E-03	-4.83

 Output table

D_ID	Split	Value_1	Value_2	Value_3
N6K_12	Str	(1.503)- ( 5.5E-03)		(-0.48)-( -4.83)
N6K_13	Ref	(1.680)-( 2.5E-03)
N6K_14	St	(1.690)-( 2.5E-03)
N6K_15	Ref			(-0.83)-( -0.63)
