Use outerjoin().

T1=table(('ABC')',[1,2,3]');
T2=table(('DEF')',[1,2,3]'+3,'Var',{'Var1','Var3'});

outerjoin(T1,T2,'MergeKeys',1)

ans = 6×3 table
    Var1    Var2    Var3
    ____    ____    ____

     A        1     NaN 
     B        2     NaN 
     C        3     NaN 
     D      NaN       4 
     E      NaN       5 
     F      NaN       6
