anchor.diff:  * Table cells that exceed the height of a single page will be truncated (see https://github.com/prawnpdf/prawn-table/issues/41[prawn-table#41]).
   * Columns cannot be assigned a 0% width (or a width less than the width of a single character); in the same vein, a column cannot be set to autowidth if width of all other columns meets or exceeds 100%; the result is that the converter with throw a Prawn::Errors::CannotFit error.
   * An inline image in a table cell will not force the column wider if the width of the image exceeds the width of the column; either reduce the image width using `pdfwidth` or increase the width of the column using `cols`; another solution is to convert the cell to an AsciiDoc table cell (see https://github.com/asciidoctor/asciidoctor-pdf/issues/830).
  -* Must use development version of prawn-table for autowidth to work on table head row.
  +* Must use <<use-dev-versions,development version of prawn-table>> for autowidth to work on table head row.
   * Must use development version of prawn for error to include font name when requested font style is missing.
   * AsciiDoc table cell leaves padding below last block (due to lack of margin collapsing).
   * Prawn does not support double-wide box drawing glyphs correctly, so box drawings aren't aligned properly in verbatim blocks (see https://github.com/prawnpdf/prawn/issues/1002[prawn#1002].

  ==== Upgrade Prawn and Extensions (optional)
  
  {project-name} uses Prawn to handle the PDF generation, which has a different release cycle.
  At times, there may be development features in Prawn and its extensions you need to use which haven't yet been released.
  No problem.
  You can still gain access to these features by installing the unreleased gems directly from GitHub.
  
  To get started, first create a [.path]_Gemfile_ in the root of your project.
  In that file, declare the gem source, the {project-handle} gem, and the prawn gem and/or one of its extension gems.
  In this example, we'll install both the prawn and prawn-table gems from GitHub.
  
  .Gemfile
  [source,ruby]
  
negative.code: source 'https://rubygems.org'
  
  gem 'asciidoctor-pdf'
  gem 'prawn-table', github: 'prawnpdf/prawn-table'
