CSV::Table#<<

table << row_or_array → self

# File tmp/rubies/ruby-3.1.3/lib/csv/table.rb, line 762
def <<(row_or_array)
  if row_or_array.is_a? Array  # append Array
    @table << Row.new(headers, row_or_array)
  else                         # append Row
    @table << row_or_array
  end

  self # for chaining
end

If row_or_array is a CSV::Row object, it is appended to the table:

Example

source = "Name,Value\nfoo,0\nbar,1\nbaz,2\n"
table = CSV.parse(source, headers: true)
table << CSV::Row.new(table.headers, ['bat', 3])
table[3] # => #<CSV::Row "Name":"bat" "Value":3>

If row_or_array is an Array, it is used to create a new CSV::Row object which is then appended to the table:

Example

table << ['bam', 4]
table[4] # => #<CSV::Row "Name":"bam" "Value":4>
