            //1.创建EXCEL中的Workbook

            mysheet.DefaultRowHeight = 30 * 20;
            mysheet.SetColumnWidth(1, 30 * 256);

            //3.创建Row中的Cell并赋值

            //【Tips】
            // 1.ForegroundColor(默认黑色)【前景颜色】BackgroundColor(默认为前景颜色的反色)【背景颜色】Pattern(必须指定，默认NoFill)【填充的图案】
            // 2.演示中使用 【前景颜色】黑色 【背景颜色】白色

            //4.创建CellStyle并应用于单元格

            //5.保存       
            FileStream file = new FileStream(@"E:\myworkbook4.xlsx", FileMode.Create);
            myworkbook.Write(file);
            file.Close();
        }
    }
}

运行后，效果如下图所示【演示了不同背景图案】
