Thank you for getting back to me so quickly,

So you're saying that I can edit the text in the pinfo.columns field,
which should mean that I can change say Protocol, where it normally puts
TCP, UDP, etc.  to any string that I want?  If so, what would be the
correct syntax to do so?  pinfo.columns:_newindex("Protocol",
"NameOfProto") doesn't seem to work, which makes me think that my syntax
is off.

You cannot add columns that way using Lua, Lua can use just the columns
that are already there under pinfo.columns ...
The outdated example you talk about does not create a column it just
switches over the src and dst addresses.
