6.13 Tables and columns (表・段組)

Synopsis

Two block containers mark table (表) and multi-column (段組) regions. Both are layout containers: they delimit a region but carry no cell, row, or column markup — the enclosed content is plain text whose alignment is set by spacing in the source. A processor marks the region; the internal structure is not machine-readable.

Notation

［＃ここから表］…［＃ここで表終わり］              ← table region
［＃ここから2段組み］…［＃ここで段組み終わり］     ← 2-column region

table-block-open   = LBRACK HASH %s"ここから表" RBRACK
table-block-close  = LBRACK HASH %s"ここで表終わり" RBRACK
columns-block-open = LBRACK HASH %s"ここから" 1*DIGIT %s"段組" [ %s"み" ] RBRACK
columns-block-close = LBRACK HASH %s"ここで段組" [ %s"み" ] %s"終わり" RBRACK

(The み okurigana is optional — 段組 and 段組み both occur.)

Parameters

count — for columns (段組), the number of columns (2段組, 3段組, …).

Semantics

A block opener/closer pair (§7.1) yields a container node — family table or columns — governing the enclosed lines; containers nest (§7.3), and pairing is by family (§7.2). The columns opener carries a count; the table opener has no parameter.
The enclosed content is ordinary flow content (§5); there is no notation for table cells, rows, or column boundaries. Visual structure depends on the source's spacing and the rendering medium.
Reference rendering (§8): <div class="aozora-container aozora-container-table">…</div> and <div class="aozora-container aozora-container-columns" data-columns="N">…</div>. The precise structure is part of the reference mapping (§8.2), not mandated.
Serialization reconstructs the opener and closer around the content (§7.6); the み okurigana is normalised to 段組み.

Error conditions

mismatched-container-close — a closer of a different family than its opener.
unrecognised-container-directive — a ここから… opener naming no known container kind (kept as a generic annotation, §6.14).

The official guide's column sub-directives — 上段 / 下段 (explicit upper/lower column), 段間に罫 (rule between columns), 段組み適用外 (exemption) — and compound forms (ここから2字下げ、4段組み) are deferred to a later revision (§10.5); a processor retains them as generic annotations.
