利用Aspose.Cells导出Datatable数据

　　面对一些的格式各样的到处数据的要求，自学了一点 Aspose.Cells中操作Excel知识，如下代码：

        /// <summary>
        /// DataTable导出Excel
        /// </summary>
        /// <param name="page">当前页面</param>
        /// <param name="my_dt">DataTable</param>
        /// <param name="fileName">文件名</param>
        /// <param name="title">输入的抬头</param>
        public static void ExportExcel(Page page, DataTable my_dt, string fileName, string title = "")
        {
            Workbook my_wb = new Workbook();
            Worksheet sheet = my_wb.Worksheets[0];
            //title的样式
            Aspose.Cells.Style t_style = my_wb.Styles[my_wb.Styles.Add()];
            t_style.HorizontalAlignment = TextAlignmentType.Center;//居中
            t_style.Font.IsBold = true;
            t_style.Font.Name = "宋体";
            t_style.Font.Size = 20;
            t_style.Borders.SetStyle(CellBorderType.Thin);//边框样式
            t_style.Borders.DiagonalStyle = CellBorderType.None;

　　　　　　　　//设置单元格背景色
　　　　　　　　t_style.ForegroundColor = System.Drawing.Color.FromArgb(153, 204, 0);
　　　　　　　　t_style.Pattern = BackgroundType.Solid;

　　　　　　  //header 样式
            Aspose.Cells.Style h_style = my_wb.Styles[my_wb.Styles.Add()];
            h_style.HorizontalAlignment = TextAlignmentType.Center;//居中
            h_style.Font.IsBold = true;
            h_style.Font.Name = "宋体";
            h_style.Font.Size = 12;
            h_style.Borders.SetStyle(CellBorderType.Thin);//边框样式
            h_style.Borders.DiagonalStyle = CellBorderType.None;//花纹
            h_style.Borders[BorderType.RightBorder].LineStyle = CellBorderType.Thin;
            //Row样式
            Aspose.Cells.Style r_style = my_wb.Styles[my_wb.Styles.Add()];
            r_style.HorizontalAlignment = TextAlignmentType.Center;//居中
            r_style.Font.IsBold = false;
            r_style.Font.Name = "宋体";
            r_style.Font.Size = 12;
            r_style.Borders.SetStyle(CellBorderType.Thin);//边框样式  
            r_style.Borders.DiagonalStyle = CellBorderType.None;
            int tempRow = 0;
            if (title != "")
            {
                //标题的写入
                sheet.Cells.Merge(0, 0, 1, my_dt.Columns.Count);//单元格从第几行第几列跨不跨行
                Range range = sheet.Cells.CreateRange(0, 0, 1, my_dt.Columns.Count);//所在区域
                Cell Cell = sheet.Cells[0, 0];//一个单元格
                Cell.PutValue(title);
                range.Style = t_style;
                tempRow++;
            }

            //列的输入
            for (var i = 0; i < my_dt.Columns.Count; i++)
            {
                sheet.Cells.Merge(tempRow, i, 1, 1);//单元格从第几行第几列跨不跨行               
                Cell m_Cell = sheet.Cells[tempRow, i];//一小格
                m_Cell.PutValue(my_dt.Columns[i].ColumnName);
                m_Cell.SetStyle(h_style);
            }
            tempRow++;
            //行的输出
            for (var i = 0; i < my_dt.Columns.Count; i++)
            {
                for (var j = 0; j < my_dt.Rows.Count; j++)
                {
                    sheet.Cells[j + tempRow, i].PutValue(my_dt.Rows[j][i]);
                    sheet.Cells[j + tempRow, i].SetStyle(r_style);
                }
            }
            sheet.Cells.SetRowHeight(0, 20);//设置行高
            //sheet.Cells.SetColumnWidth(1, 20);//设置列宽
            sheet.AutoFitColumns();  //列宽自动匹配，当列宽过长是收缩

            fileName = System.Web.HttpUtility.UrlEncode(fileName + ".xls", System.Text.Encoding.UTF8);//文件名编码

            my_wb.Save(fileName, FileFormatType.Excel2003, SaveType.OpenInExcel, page.Response);
            page.Response.End();

        }
