ReportLabを使用して最初のプログラムを実行していますが、ページ分割がどこに落ちるかが事前にわからず、問題が発生しています。物事を単純にするために、私はを使用していSimpleDocTemplateます。私のフローアブルは次のようになります。
flowables = [Paragraph("Some title", style=headerParagraphStyle),
Spacer(0, 10),
Paragraph("first paragraph", style=bodyParagraphStyle),
Paragraph("second paragraph", style=bodyParagraphStyle),
...
Paragraph("nth paragraph", style=bodyParagraphStyle),
PageBreak(),
Paragraph("Some title", style=headerParagraphStyle),
Spacer(0, 10),
Paragraph("first paragraph", style=bodyParagraphStyle),
Paragraph("second paragraph", style=bodyParagraphStyle),
...
Paragraph("mth paragraph", style=bodyParagraphStyle),
PageBreak(),
...]
PDFを作成すると、本文の段落が1ページに収まる限り、すべてが正常に機能しnますmが、それらがいっぱいになると、次のようなエラーが発生します。
reportlab.platypus.doctemplate.LayoutError: Flowable <Paragraph at 0xb79800 frame=normal>20th paragraph: too large on page 3
これが私に起こり続ける理由の正当な理由を見つけることができないようです。助言がありますか？PageBreaks（）を削除しても、これは実行されます。すべての段落は比較的短く、ほとんどの場合、1行あたり1文未満です。
ETA：エラーを生成しているすべてのコード（マイナー識別子を削除）を投稿しています。CSVファイルを読み取るように変換したので、その内容も投稿しました。このコードを実行したときに生成される正確なエラーは次のとおりです。
トレースバック（最後の最後の呼び出し）：

LayoutError（ident）を発生させます
reportlab.platypus.doctemplate.LayoutError：Flowable追加のコメントと改善のための提案：3ページで大きすぎます
一部のデバッグ作業では、エラーはこの段落の結果であることが示されています（ただし、コンテンツの長さによっては他のフロー可能である可能性があります）handle_frameEnd()。提案？
