Empid code loc port

102        B      zx  78
103         A     cg  12
104         G     xy   78

2.csv contains follwing data-

Empid code loc port
101       A       gf  01
102       B        zx  78
103       C        cg   32
104      M        cf     45

So my output should be like this-

Empid code loc port  Empid code loc port
101                 xy             101              gf     
103      A               12       103     C            32
104     G         xy    78      103     M    cf    45
