Remove duplicates and blanks

amitchandak  meanwhile i have created a mockup of what i expected, and also new columns Called NExito and NFracaso, the following query :

DatosExtra = 
   UNION(
       ROW("Etapa";1;"Exito"; 1;"Fracaso";"";"NExito";"a";"NFracaso";"");
        ROW("Etapa";2;"Exito";3;"Fracaso";2;"NExito";"c";"NFracaso";"b");
        ROW("Etapa";3;"Exito";5;"Fracaso";4;"NExito";"e";"NFracaso";"d");
        ROW("Etapa";4;"Exito";7;"Fracaso";6;"NExito";"f";"NFracaso";"g");
        ROW("Etapa";5;"Exito";9;"Fracaso";8;"NExito";"i";"NFracaso";"h");
        ROW("Etapa";6;"Exito";11;"Fracaso";10;"NExito";"k";"NFracaso";"j");
        ROW("Etapa";7;"Exito";13;"Fracaso";12;"NExito";"m";"NFracaso";"l")
       )

Returns the following (what i expected):

So, is there something i can do to replicate that? By making rows or columns?
