SQL Server データベースと対話する C# WPF アプリケーションがあります。アプリケーションでは、ユーザーが何らかのデータを SQL から Excel にエクスポートできるようにしたいと考えています。最初にデータテーブルを埋めてから、それをExcelファイルにエクスポートしようとしています。このSQLクエリで満たされたデータテーブルをエクスポートするタスクに直面するまで、すべてがうまくいきました：
次のような書式設定された Excel ファイルに変換します。
では、1 つの地域のすべての販売の詳細を Excel ファイルで並べ替えるにはどうすればよいでしょうか。長い間、この問題について頭を悩ませています。助けてください!
誰かが類推して問題を解決する必要がある場合、私はこのコードで目標を達成しました:

{
if ((currentId != (int)dt.Rows[i][0]))

if (i != 0)
