Pictured above, for a great god:
I am now doing a custom lua plug-in to parse the data, but DissectorTable. Get the parameters how to fill in, I thought I will get to the data according to below to fill out the data, but no:

The local test_table=DissectorTable. Get (" wtap_encap ")
Test_table: add (104, my_proto)

Above two parameters can not achieve a goal, have know who to ask
