                        WriteLog(ex, "数据异常", false);
                        continue;
                    }

                //设置列的宽度
                worksheet.Cells.SetColumnWidthPixel(0, 150);
                worksheet.Cells.SetColumnWidthPixel(1, 150);
                workbook.Save(FileFullName);

 //合并单元格
worksheet.Cells.Merge(rowIndex - userRowSpan, 0, userRowSpan, 1);

以上以从listview导出数据到excel为例
