Module: Asciidoctor::PDF::Rhrev::TableCellChangeBarFlagging

Defined in:
lib/asciidoctor/rhrev/table_cell_change_bar_patch.rb

Overview

Flags the marked cells while the table is being built from asciidoctor-pdf's cell data, before any cell object exists for a plain cell. Prawn extends every document instance with its table interface at construction, so the constructor is the reliable hook; a module prepended on the converter never sees the table call.
