NPOI导出EXCEL遇到换行符时，改变单元格的样式~！

foreach (DataColumn column in SourceTable.Columns)
{
    dataRow.CreateCell(column.Ordinal).SetCellValue(row[column].ToString());

    if (row[column].ToString().Contains("\n"))
    {
        //將目前欄位的CellStyle設定為自動換行
        HSSFCellStyle cs = workbook.CreateCellStyle();
        cs.WrapText = true;
        dataRow.GetCell(column.Ordinal).CellStyle = cs;

        //因為換行所以愈設幫他Row的高度變成兩倍
        dataRow.HeightInPoints = 2 * sheet.DefaultRowHeight / 20;
    }

}
