rails 6.1: cannot load such file -- prawn-table

I am using the prawn gem to create pdf's. So, to create tables requires using the separate prawn-table gem.

For some reason, I am unable to require the prawn table gem and have no clues as to why.

The result is:

require': cannot load such file -- prawn-table (LoadError)

For some reason, the prawn-table gem cannot be loaded. Why not?

The gems exist in the gem env path (see below):

bundle info prawn
  * prawn (2.4.0)
        Summary: A fast and nimble PDF generator for Ruby
        Homepage: http://prawnpdf.org
        Path: /home/cb/.gem/ruby/2.6.6/gems/prawn-2.4.0

bundle info prawn-table
  * prawn-table (0.2.2)
        Summary: Provides tables for PrawnPDF
        Homepage: https://github.com/prawnpdf/prawn-table
        Path: /home/cb/.gem/ruby/2.6.6/gems/prawn-table-0.2.2

I call the prawn generator like so...

require 'prawn'
require 'prawn/measurement_extensions'
require 'prawn-table'

def generate_pdf(invoice, mode)
 Prawn::Document.generate(invoice.file, margin_top: 0, page_size: 'A4',
                                           info:
  {...

which results in:

invoicer generate --mode development

IMO instead of

require "prawn-table"

you should use

require "prawn/table"
