iText開発者は 'onStartPage'にコンテンツを追加しないで、代わりに' onEndPage'を使うよう強く勧めます。そして、 'document.add'は使用しません。 – mkl

答えて

HeaderFooterPageEventsクラスに位置して（あなたの要件に応じて）のいずれかあなたの次のコード行のいずれかを削除してください：

追加したい場合あなたの体にテーブルを追加し、次の行を削除してください：

table.writeSelectedRows(0, -1, rect.getRight() - table.getTotalWidth(), document.top(), writer.getDirectContent());

テーブルをページヘッダーに追加する場合は、

document.add(table)

ただし、一部の書式設定が必要な場合があります。

ありがとう、それは正常に働いた。私は "document.add（table）"とコメントし、 "table.writeSelectedRows"にいくつかの変更を加えて、テーブルを一番上に持ってきました。 –
