What about extracting the column info? Can I get the IP address as a
string from the SOURCe or DESTINATION column of the packet(s) in
question?

So is this a plugin dissector or a plugin tap?
If it's a dissector, then:

yes - your dissector will be passed a packet_info pointer, which we'll
call "pinfo", and:
pinfo->src is an "address" structure with the packet's source
address;
pinfo->src is an "address" structure with the packet's
destination address.
NOTE: it could be an IPv4 or IPv6 address. An "address" structure has a
member named "type" which could be AT_IPv4 or AT_IPv6 for the source or
destination address of an IP packet.

It doesn't - the APIs for getting and processing packet data are
platform-independent.
