How to create a custom cell type?

[ferdynator]

I would like to use this library in combination with prawn-html, but I am unsure how to render HTML into a table cell.

My current approach is to create a custom cell class:

class HtmlCell < Prawn::Table::Cell
  def draw_content
    PrawnHtml.append_html(self, content)
  end
end

and use it as such:

class PrintView
  include Prawn::View

  def print_section_x
    table [["header"], [HtmlCell.make(self, "<p>Test</p>")]]
  end
end

but unfortunately the draw_content method is never called. The code clearly states that the Cell type can be extended:

prawn-table/lib/prawn/table/cell.rb

Lines 48 to 50 in 38b5bdb

	# Please subclass me if you want new content types! I'm designed to be very
	# extensible. See the different standard Cell subclasses in
	# lib/prawn/table/cell/*.rb for a template.

but I can't find any examples. Is this currently possible?
