如何从DataFrame对象或 JuliaDBIndexedTable对象中获取列名？这可能吗？

using JuliaDB
import DataFrames
DF = DataFrames

# CREATES AN EXAMPLE TABLE WITH JULIADB

colnames = [:samples, :A, :B, :C, :D]
primary_key = [:samples]
coltypes = [Int[], Float64[],Float64[],Float64[],Float64[]]
sample_sizes = [100,200,300]
example_values = (1, 0.4, 0.3, 0.2, 0.1)

mytable = table(coltypes..., names=colnames, pkey=primary_key) # initialize empty table

# add some data to table
for i in sample_sizes
    example_values = (i, 0.4, 0.3, 0.2, 0.1)
    table_params = [(col=>val) for (col,val) in zip(colnames, example_values)]

    push!(rows(mytable), …
