set MINUS operation using VBscript on excel sheets

问题

Is it possible to implement Set operation on sheets of Excel using vbscript? Say A - A'=A1

Suppose i do have a matrix A, as below :

 PID  T1   T1Sdate  T1Assign  T2   T2Sdate  T2Assign   T3   T3Sdate  T3Assign   T4    T4Sdate  T4Assign

 10   A      10/11    Ram      B      2/5     Hari     X     03/03     Peter     L      04/09     Mikel

 20   A      10/11    Kajal    T      7/5     Lisa     X     03/03     Peter     L      04/07     Sila

 25   Y      10/11    Sila     T      7/5     Lisa     X     02/03     Peter     L      17/07     Mikel

From above i got the below matrix A':

 PID  T1   T1Sdate  T1Assign  T2   T2Sdate  T2Assign   T3   T3Sdate  T3Assign   T4    T4Sdate  T4Assign

 10   A      10/11    Ram                              X     03/03     Peter     L      04/09     Mikel

 20   A      10/11    Kajal    T      7/5     Lisa    

 25                                                    X     02/03     Peter     L      17/07     Mikel

Now can i get the output matrix using A - A'

 PID  T1   T1Sdate  T1Assign  T2   T2Sdate  T2Assign   T3   T3Sdate  T3Assign   T4    T4Sdate  T4Assign

 10                            B      2/5     Hari    

 20                                                   X     03/03     Peter     L      04/07        Sila

 25   Y      10/11    Sila     T      7/5     Lisa
