Is it possible to initialize an empty JuliaDB table with columns names?
Yes, it is possible.
This is the source where you can learn it from direct experience (JuliaDB.jl/basics.md at master · JuliaData/JuliaDB.jl · GitHub) and this is an example of code to instantiate it, once you already added the package:
using JuliaDB
dblog = table((ObjectID=Int[], Iteration=Int[], Events=[], States=Matrix{Float64}[]); pkey = [:ObjectID, :Iter])
The code it’s just an example, and you should be able to replicate it. In this case, it’s an IndexedTable with 2 primary keys, specified by the ‘pkey’ attribute.
Ánimo con el trabajo!
