保存とレンダリング | 用途特化型シート | SpreadJS（スプレッドJS）チュートリアルデモアプリケーション

JSONのシリアル化と逆シリアル化テーブルシートのJSONシリアル化と逆シリアル化は、ワークブックの toJSON と fromJSON メソッドを使用して行われます。 SJS形式のシリアル化と逆シリアル化テーブルシートのSJS形式のシリアル化と逆シリアル化は、ワークブックの save と openメソッドを使用して行われます。 ExcelのエクスポートテーブルシートのExcelへのエクスポートは、ワークブックの exportメソッドを使用して行われます。 PDFのエクスポートテーブルシートのPDFへのエクスポートは、ワークブックのsavePDFメソッドを使用して行われます。印刷またはPDFへのエクスポートのために、printInfoメソッドを使用して印刷情報をカスタマイズできます。印刷テーブルシートの印刷は、ワークブックのprintメソッドを使用して行われます。テーブルシートは、columnStart／columnEnd／rowStart/rowEnd、repeatColumnStart／repeatColumnEnd／repeatRowStart／repeatRowEnd、およびshowRowHeaderを除く、印刷情報のほとんどのプロパティをサポートします。
