You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: test_table.rb
    path of file: ./repos/jruby/test/mri/csv
    
    the code of the file until where you have to start completion: # -*- coding: utf-8 -*-
# frozen_string_literal: false

require_relative "helper"

class TestCSVTable < Test::Unit::TestCase
  extend DifferentOFS

    enum = @table.delete_if
    assert_instance_of(Enumerator, enum)
    assert_equal(@table.size, enum.size)

    # verify that we can chain the call
    assert_equal(@table, enum.each { |row| (row["B"] % 2).zero? })

    # verify resulting table
    assert_equal(<<-CSV, @table.to_csv)
