//说明：设置单元格背景与图案

//1.创建EXCEL中的Workbook
IWorkbook myworkbook = new XSSFWorkbook();

//2.创建Workbook中的Sheet
ISheet mysheet = myworkbook.CreateSheet("sheet1");
mysheet.DefaultRowHeight = 30 * 20;
mysheet.SetColumnWidth(1, 30 * 256);

//3.创建Row中的Cell并赋值
IRow row0 = mysheet.CreateRow(0); row0.CreateCell(0).SetCellValue(""); row0.CreateCell(1).SetCellValue("NoFill");
IRow row1 = mysheet.CreateRow(1); row1.CreateCell(0).SetCellValue(""); row1.CreateCell(1).SetCellValue("SolidForeground");
IRow row2 = mysheet.CreateRow(2); row2.CreateCell(0).SetCellValue(""); row2.CreateCell(1).SetCellValue("FineDots");
IRow row3 = mysheet.CreateRow(3); row3.CreateCell(0).SetCellValue(""); row3.CreateCell(1).SetCellValue("AltBars");
IRow row4 = mysheet.CreateRow(4); row4.CreateCell(0).SetCellValue(""); row4.CreateCell(1).SetCellValue("SparseDots");
IRow row5 = mysheet.CreateRow(5); row5.CreateCell(0).SetCellValue(""); row5.CreateCell(1).SetCellValue("ThickHorizontalBands");
IRow row6 = mysheet.CreateRow(6); row6.CreateCell(0).SetCellValue(""); row6.CreateCell(1).SetCellValue("ThickVerticalBands");
IRow row7 = mysheet.CreateRow(7); row7.CreateCell(0).SetCellValue(""); row7.CreateCell(1).SetCellValue("ThickBackwardDiagonals");
IRow row8 = mysheet.CreateRow(8); row8.CreateCell(0).SetCellValue(""); row8.CreateCell(1).SetCellValue("ThickForwardDiagonals");
IRow row9 = mysheet.CreateRow(9); row9.CreateCell(0).SetCellValue(""); row9.CreateCell(1).SetCellValue("BigSpots");
IRow row10 = mysheet.CreateRow(10); row10.CreateCell(0).SetCellValue(""); row10.CreateCell(1).SetCellValue("Bricks");
IRow row11 = mysheet.CreateRow(11); row11.CreateCell(0).SetCellValue(""); row11.CreateCell(1).SetCellValue("ThinHorizontalBands");
IRow row12 = mysheet.CreateRow(12); row12.CreateCell(0).SetCellValue(""); row12.CreateCell(1).SetCellValue("ThinVerticalBands");
IRow row13 = mysheet.CreateRow(13); row13.CreateCell(0).SetCellValue(""); row13.CreateCell(1).SetCellValue("ThinBackwardDiagonals");
IRow row14 = mysheet.CreateRow(14); row14.CreateCell(0).SetCellValue(""); row14.CreateCell(1).SetCellValue("ThinForwardDiagonals");
IRow row15 = mysheet.CreateRow(15); row15.CreateCell(0).SetCellValue(""); row15.CreateCell(1).SetCellValue("Squares");
IRow row16 = mysheet.CreateRow(16); row16.CreateCell(0).SetCellValue(""); row16.CreateCell(1).SetCellValue("Diamonds");
IRow row17 = mysheet.CreateRow(17); row17.CreateCell(0).SetCellValue(""); row17.CreateCell(1).SetCellValue("LessDots");
IRow row18 = mysheet.CreateRow(18); row18.CreateCell(0).SetCellValue(""); row18.CreateCell(1).SetCellValue("LeastDots");

//【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);
