Optional column in Table

This clever piece of code, was written by ASMI, and it generates a table of coordinates after picking a pline

open or closed. I would like like to modify it slightly, so there is an option

of showing or not showing the last column that shows "Radius"

So the user will have either 3 columns or 4 columns. Can someone tweek it please?

thanks

Never mind folks - I have worked it out myself....

Can you, please, show us your "tweaked" lisp routine?
