私はそれを次のように絞り込みました：
//aantal auto's
Row aantalAutosRow = new Row();
aantalAutosRow.RowIndex = Convert.ToUInt32((tblXML.Rows.Count) + 2);
Cell aantalAutosCell = new Cell();
aantalAutosCell.CellReference = getColumnName(1);
aantalAutosCell.CellValue = new CellValue("Hoi");
aantalAutosRow.Append(aantalAutosCell);
sheetData.Append(aantalAutosRow);
これにより、Excel でファイル (sheet.xml) の修正を求めるプロンプトが表示されたときに [はい] をクリックすると、セルが生成されます。

私がやっていることが Excel にとって違法であると誰かに教えてもらえますか? それを修正すると、ExcelはSharedStringsを作成すると思います。私は SharedStrings を使ったことがありません。そうする必要がないことを願っています。
