Short answer: Not directly just yet, but with RTF being a text format 
you could write a function to add column widths to RTF on export.


Longer answer:

Exporting the contents of a field does not export the properties of a 
field object itself.  But with the enhancements of v5.4 we now have MANY 
more paragraph-level properties.

So we would expect that setting the tabStops (or the newer tabWidths, 
sometimes a more useful alternative) of each line within the field would 
produce rtFText that includes those column specifiers.

But alas, I just tried it and it does not.

If someone has time to catalog those RTF features that LC now supports 
with fields but does not include in rtfText it may be helpful to file an 
enhancement request to bring rtfText current with the full range of 
relevant text properties.

RtfText is not designed to be able to reproduce an LC field with 
complete fidelity (that's htmlText's role), but should include all 
attributes common to both LC and RTF, and AFAIK did cover almost all of 
them until v5.4 introduced all the new paragraph and inline styling 
properties.

For now, a workaround would be to write a function that walks through 
the rows and columns of a field, including column width specifiers as 
you go.   Tedious, but doable.
