    class Program3
    {
        static void Main(string[] args)
        {
            //说明:设置单元格对齐方式

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

            //2.创建Workbook中的Sheet        
            ISheet mysheet = myworkbook.CreateSheet("sheet1");

            mysheet.SetColumnWidth(0, 24 * 256);
            mysheet.SetColumnWidth(1, 24 * 256);
            mysheet.SetColumnWidth(2, 24 * 256);
            mysheet.SetColumnWidth(3, 24 * 256);

            //3.创建Row中的Cell并赋值
            IRow row0 = mysheet.CreateRow(0);
            row0.Height = 50 * 20;
            row0.CreateCell(0).SetCellValue("对齐方式");
            row0.CreateCell(1).SetCellValue("对齐方式");
            row0.CreateCell(2).SetCellValue("对齐方式");
            row0.CreateCell(3).SetCellValue("对齐方式");

            IRow row1 = mysheet.CreateRow(1);
            row1.Height = 50 * 20;
            row1.CreateCell(0).SetCellValue("对齐方式");
            row1.CreateCell(1).SetCellValue("Shanghai is the largest city by population in ");
            row1.CreateCell(2).SetCellValue("对齐方式");
            row1.CreateCell(3).SetCellValue("对齐方式");

            //4.创建CellStyle
            ICellStyle style0 = myworkbook.CreateCellStyle();
            style0.Alignment = HorizontalAlignment.General;//【General】数字、时间默认:右对齐;BOOL:默认居中;字符串:默认左对齐

            ICellStyle style1 = myworkbook.CreateCellStyle();
            style1.Alignment = HorizontalAlignment.Left;//【Left】左对齐

            ICellStyle style2 = myworkbook.CreateCellStyle();
            style2.Alignment = HorizontalAlignment.Center;//【Center】居中

            ICellStyle style3 = myworkbook.CreateCellStyle();
            style3.Alignment = HorizontalAlignment.Right;//【Right】右对齐

            ICellStyle style4 = myworkbook.CreateCellStyle();
            style4.Alignment = HorizontalAlignment.Fill;//【Fill】填充

            ICellStyle style5 = myworkbook.CreateCellStyle();
            style5.Alignment = HorizontalAlignment.Justify;//【Justify】两端对齐[会自动换行](主要针对英文)

            ICellStyle style6 = myworkbook.CreateCellStyle();
            style6.Alignment = HorizontalAlignment.CenterSelection;//【CenterSelection】跨列居中

            ICellStyle style7 = myworkbook.CreateCellStyle();
            style7.Alignment = HorizontalAlignment.Distributed;//【Distributed】分散对齐[会自动换行]

            //【Tips】
            // 1.通过ICellStyle的VerticalAlignment属性可以设置垂直对齐模式与水平对齐无异 不再演示
            // 2.通过ISheet的SetDefaultColumnStyle(int column, ICellStyle style)方法可以设置整列的默认单元格样式;
            
            //5.将CellStyle应用于具体单元格
            row0.GetCell(0).CellStyle = style0;
            row0.GetCell(1).CellStyle = style1;
            row0.GetCell(2).CellStyle = style2;
            row0.GetCell(3).CellStyle = style3;

            row1.GetCell(0).CellStyle = style4;
            row1.GetCell(1).CellStyle = style5;
            row1.GetCell(2).CellStyle = style6;
            row1.GetCell(3).CellStyle = style7;

            //6.保存       
            FileStream file = new FileStream(@"E:\myworkbook3.xlsx", FileMode.Create);
            myworkbook.Write(file);
            file.Close();
        }
    }
}
运行后,效果如下图所示
