Something like
iplot,x,y,z,vert_colors=colors,/
insert_colorbar,rgb_table=my_colortable
Where my_colortable is a 3x256 or 256x3 array with the r,g,b values
for each of the 256 color indexes.

OK for iplot!

OK, what is the command? iplot,x,y,z,rgb_table=my_colortable,/
insert_colorbar ?
Do I need the color=.... keyword?

That is using a standard table (1). If you made your own colortable,
pass it (3x256 or 256x3 array) as the value of rgb_table.

It is much easier to it with iplot, instead of xplot3d. For instance:
x=findgen(10) & y=x & z=x & colors=x*255/9.
iplot,x,y,z,vert_colors=colors,/insert_colorbar,rgb_table=1
