This is exactly what I state:

  • the (s=1,id=1,a=copy(df[1,:]),r=missing, m=missing) named tuple is always expanded to multiple columns as it is top-level (not wrapped in anything);
  • the copy(df[1,:]) named tuple is not expanded and treated as a single column because it is wrapped (in this case in another named tuple)
