Bueno es un poco aburrido, pero básicamente lo que haces es un ciclo para crear una a una las columnas que desees.
Para crear una columna por código usas la siguiente sintaxis. Te envío toda la sintaxis completa con cada una de sus opciones
dw_1.Modify(&
"create column( id=<an integer> tabsequence=<an integer> accelerator='<a single letter>' moveable=<0 - False, 1 - True> resizeable=<0 - False, 1 - True> pointer='<Arrow!, Cross!, HourGlass!, IBeam!, Icon!, Size!, SizeNESW!, SizeNS!, SizeNWSE!, SizeWE!, UpArrow!, or cursor filename (with path)>' band=<Detail, Footer, Header, Header.<group #>, Summary, Trailer.<group #>, Background, Foreground>" + &
