When rendering on a tagged Prawn::Document (marked: true), tables now automatically emit PDF structure elements: - <Table> wraps the entire table - <TR> wraps each row - <TH> with /Scope /Column for header cells - <TD> for data cells Header cells are detected automatically from the table's header: option. Backgrounds and borders are wrapped as /Artifact (decorative content not read by screen readers). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Summary
Adds automatic PDF structure tagging for tables when rendered on a tagged
Prawn::Document(one created withmarked: true).When tagged mode is active,
pdf.table(data, header: true)automatically emits:<Table>wrapping the entire table<TR>wrapping each row<TH>with/Scope /Columnfor cells in header rows<TD>for data cells/Artifact(excluded from screen readers)No API changes required — existing
pdf.table()calls gain accessibility tagging automatically.Changes:
Table#draw— wraps instructure_container(:Table)when taggedCell.draw_cells— emits<TR>per row,<TH>/<TD>per cell; backgrounds/borders as artifactsCell#header?/Cell#is_header_cell— accessor for header cell detectionTable#mark_header_cells— auto-marks cells in header rows based onheader:optionGemfile— supportsGemfile.localfor local gem overridesDepends on prawnpdf/prawn#1391 and prawnpdf/pdf-core#67.
