ASP.NET MVC5+EF6+EasyUI 後臺管理系統（88）-Excel導入和導出-主從表結構導出

前言

前面一篇詳細講解了導入導出，本節演示混合結構的導出功能！同時提供代碼下載..

先看效果圖：這個一個混合的Excel，列表與自定義信息的混合！

　　我們的步驟大概分爲以下幾步

• 1.模擬數據庫數據
• 2.創建工作簿
• 3.填充固定數據
• 4.合併單元格
• 5.處理動態數據

　　數據及環境準備

　　創建一個新的Asp.Net MVC5項目，並從Nuget包安裝ClosedXML

　　

　　爲了更好的跟真實數據結合，我們需要模擬一些靜態數據，新建2個模型來保存數據

  public class SchoolClass
    {

        public string Id { get; set; }//班級標示
        public string Name { get; set; }//班級名稱
        public string Manager { get; set; }//班主任姓名
        public string Manager2 { get; set; }//副班主任姓名
        public string PhoneNumber { get; set; }//班主任聯繫電話
        public string PhoneNumber2 { get; set; }//副主任聯繫電話
        public string Remark { get; set; } //班級說明
        public List<Students> stuList { get; set; }//一個班級對應多個學生
    }

    public class Students
    {
        public string Id { get; set; }//學號
        public string Name { get; set; }//姓名
        public string Sex { get; set; }//性別
        public string Age { get; set; }//年齡
        public string Point { get; set; }//年度得分
        public string PhoneNumber { get; set; }//電話
    }

注：從模型看出，這是一個班級信息表，一個班級對應多個學生的信息！

實現方式

1.新建一個控制器並填充數據

 public ActionResult Index()
 {
            //模擬數據庫賦值，一個班級對應多個學生
            SchoolClass model = new SchoolClass();
            model.Id = "CLS0001";
            model.Name = "三年二班";
            model.Manager = "黃SIR";
            model.PhoneNumber = "13800138000";
            model.Manager2 = "李SIR";
            model.PhoneNumber2 = "13888138666";
            model.Remark = "這是一段有很多個字的班級說明，只有足夠長的字，才能證明這段文字很長，如果100個字還不夠長，那麼就再來100個字！";
            model.stuList = new List<Students>();
            model.stuList.Add(new Students() { Id = "STU0001", Name = "牛掰掰", Sex = "男", Age = "23",Point="80", PhoneNumber = "13545678547" });
            model.stuList.Add(new Students() { Id = "STU0002", Name = "張三", Sex = "女", Age = "23", Point = "70", PhoneNumber = "13545654874" });
            model.stuList.Add(new Students() { Id = "STU0003", Name = "李四", Sex = "女", Age = "25", Point = "50", PhoneNumber = "13545633552" });
            model.stuList.Add(new Students() { Id = "STU0004", Name = "王五", Sex = "男", Age = "22", Point = "66", PhoneNumber = "13566885541" });
            model.stuList.Add(new Students() { Id = "STU0005", Name = "林蛋大", Sex = "男", Age = "26", Point = "95", PhoneNumber = "13821298458" });
            model.stuList.Add(new Students() { Id = "STU0006", Name = "劉麗麗", Sex = "女", Age = "19", Point = "95", PhoneNumber = "13821298458" });

}

 

2.創建作業本並填充表頭

紅框中表示表示表頭位置，我們Excel大家都知道是按位置標示的，比如我點中的三年二班表示的是B3（左上角顯示），所有我們填充表頭也是這麼做

   var wb = new XLWorkbook();
            var ws = wb.Worksheets.Add("班級");
            ws.Cell("A1").Value = model.Name+"班級信息表";
            //標題
            ws.Cell("A2").Value = "班級代號";
            ws.Cell("B2").Value = "班級名稱";
            ws.Cell("C2").Value = "班主任";
            ws.Cell("D2").Value = "聯繫電話";
            ws.Cell("E2").Value = "副班主任";
            ws.Cell("F2").Value = "聯繫電話";
            //主表內容
            ws.Cell("A3").Value = model.Id;
            ws.Cell("B3").Value = model.Name;
            ws.Cell("C3").Value = model.Manager;
            ws.Cell("D3").Value = model.PhoneNumber;
            ws.Cell("E3").Value = model.Manager2;
            ws.Cell("F3").Value = model.PhoneNumber2;
            ws.Cell("A4").Value = model.Remark;//說明

            //明細表標題
            ws.Cell("A5").Value = "學號";
            ws.Cell("B5").Value = "姓名";
            ws.Cell("C5").Value = "性別";
            ws.Cell("D5").Value = "年齡";
            ws.Cell("E5").Value = "得分";
            ws.Cell("F5").Value = "電話號碼";

所以位置決定內容，填充表頭後。我們再填充列表

   for (int i = 0; i < model.stuList.Count(); i++)
            {
                ws.Cell(i + 6, 1).Value = model.stuList[i].Id;
                ws.Cell(i + 6, 2).Value = model.stuList[i].Name;
                ws.Cell(i + 6, 3).Value = model.stuList[i].Sex;
                ws.Cell(i + 6, 4).Value = model.stuList[i].Age;
                ws.Cell(i + 6, 5).Value = model.stuList[i].PhoneNumber;
                ws.Cell(i + 6, 6).Value = model.stuList[i].PhoneNumber;
            }

由於我們列表數據是動態並不是固定的，工作簿也是支持二維數組位置填充！看代碼從第6行開始，一行一行填充！

3.合併和填充

 　　　　　　var rngTable = ws.Range("A1:F" + (model.stuList.Count() + 5));

            //合併表頭
            var rngHeaders = rngTable.Range("A1:F1");
            ws.Row(1).Height = 20;
            rngHeaders.FirstCell().Style
             .Font.SetBold()
             .Fill.SetBackgroundColor(XLColor.Buff)
             .Alignment.SetHorizontal(XLAlignmentHorizontalValues.Center);
            rngHeaders.FirstRow().Merge();

            //第二行表頭樣式
            rngHeaders = rngTable.Range("A2:F2"); // The address is relative to rngTable (NOT the worksheet)
            rngHeaders.Style.Alignment.Horizontal = XLAlignmentHorizontalValues.Center;
            rngHeaders.Style.Font.Bold = true;
            //rngHeaders.Style.Font.FontColor = XLColor.DarkBlue;
            rngHeaders.Style.Fill.BackgroundColor = XLColor.Aqua;


            //合併說明
            var rngRemark = rngTable.Range("A4:F4");
            ws.Row(4).Height = 30;
            rngRemark.Style.Alignment.WrapText = true;
            rngRemark.FirstCell().Comment.Style.Size.SetAutomaticSize();
            rngRemark.FirstRow().Merge();

            rngTable = ws.Range("A5:F" + (model.stuList.Count() + 5));
            var excelTable = rngTable.CreateTable();

            ws.Columns().AdjustToContents(); 

最後我們要做：填充顏色，合併單元格就好，比如說明:說明內容我們是填充在A4，但是我們要合併A1-F4的位置

 public ActionResult Index()
        {
            //模擬數據庫賦值，一個班級對應多個學生
            SchoolClass model = new SchoolClass();
            model.Id = "CLS0001";
            model.Name = "三年二班";
            model.Manager = "黃SIR";
            model.PhoneNumber = "13800138000";
            model.Manager2 = "李SIR";
            model.PhoneNumber2 = "13888138666";
            model.Remark = "這是一段有很多個字的班級說明，只有足夠長的字，才能證明這段文字很長，如果100個字還不夠長，那麼就再來100個字！";
            model.stuList = new List<Students>();
            model.stuList.Add(new Students() { Id = "STU0001", Name = "牛掰掰", Sex = "男", Age = "23",Point="80", PhoneNumber = "13545678547" });
            model.stuList.Add(new Students() { Id = "STU0002", Name = "張三", Sex = "女", Age = "23", Point = "70", PhoneNumber = "13545654874" });
            model.stuList.Add(new Students() { Id = "STU0003", Name = "李四", Sex = "女", Age = "25", Point = "50", PhoneNumber = "13545633552" });
            model.stuList.Add(new Students() { Id = "STU0004", Name = "王五", Sex = "男", Age = "22", Point = "66", PhoneNumber = "13566885541" });
            model.stuList.Add(new Students() { Id = "STU0005", Name = "林蛋大", Sex = "男", Age = "26", Point = "95", PhoneNumber = "13821298458" });
            model.stuList.Add(new Students() { Id = "STU0006", Name = "劉麗麗", Sex = "女", Age = "19", Point = "95", PhoneNumber = "13821298458" });



            var wb = new XLWorkbook();
            var ws = wb.Worksheets.Add("班級");
            ws.Cell("A1").Value = model.Name+"班級信息表";
            //標題
            ws.Cell("A2").Value = "班級代號";
            ws.Cell("B2").Value = "班級名稱";
            ws.Cell("C2").Value = "班主任";
            ws.Cell("D2").Value = "聯繫電話";
            ws.Cell("E2").Value = "副班主任";
            ws.Cell("F2").Value = "聯繫電話";
            //主表內容
            ws.Cell("A3").Value = model.Id;
            ws.Cell("B3").Value = model.Name;
            ws.Cell("C3").Value = model.Manager;
            ws.Cell("D3").Value = model.PhoneNumber;
            ws.Cell("E3").Value = model.Manager2;
            ws.Cell("F3").Value = model.PhoneNumber2;
            ws.Cell("A4").Value = model.Remark;//說明

            //明細表標題
            ws.Cell("A5").Value = "學號";
            ws.Cell("B5").Value = "姓名";
            ws.Cell("C5").Value = "性別";
            ws.Cell("D5").Value = "年齡";
            ws.Cell("E5").Value = "得分";
            ws.Cell("F5").Value = "電話號碼";

   

            for (int i = 0; i < model.stuList.Count(); i++)
            {
                ws.Cell(i + 6, 1).Value = model.stuList[i].Id;
                ws.Cell(i + 6, 2).Value = model.stuList[i].Name;
                ws.Cell(i + 6, 3).Value = model.stuList[i].Sex;
                ws.Cell(i + 6, 4).Value = model.stuList[i].Age;
                ws.Cell(i + 6, 5).Value = model.stuList[i].PhoneNumber;
                ws.Cell(i + 6, 6).Value = model.stuList[i].PhoneNumber;
            }

            var rngTable = ws.Range("A1:F" + (model.stuList.Count() + 5));

            //合併表頭
            var rngHeaders = rngTable.Range("A1:F1");
            ws.Row(1).Height = 20;
            rngHeaders.FirstCell().Style
             .Font.SetBold()
             .Fill.SetBackgroundColor(XLColor.Buff)
             .Alignment.SetHorizontal(XLAlignmentHorizontalValues.Center);
            rngHeaders.FirstRow().Merge();

            //第二行表頭樣式
            rngHeaders = rngTable.Range("A2:F2"); // The address is relative to rngTable (NOT the worksheet)
            rngHeaders.Style.Alignment.Horizontal = XLAlignmentHorizontalValues.Center;
            rngHeaders.Style.Font.Bold = true;
            //rngHeaders.Style.Font.FontColor = XLColor.DarkBlue;
            rngHeaders.Style.Fill.BackgroundColor = XLColor.Aqua;


            //合併說明

            rngRemark.FirstCell().Comment.Style.Size.SetAutomaticSize();
            rngRemark.FirstRow().Merge();

            rngTable = ws.Range("A5:F" + (model.stuList.Count() + 5));
            var excelTable = rngTable.CreateTable();

            ws.Columns().AdjustToContents(); 

            var exportFileName = string.Concat(
                    "ExcelSample",
                    DateTime.Now.ToString("yyyyMMddHHmmss"),
                    ".xlsx");

            return new ExportExcelResult(wb)
            {
                SheetName = "人員列表",
                FileName = exportFileName,
                Workbook = wb
            };


        }

總結

代碼不難看懂，基本情景我都用到：比如合併、高度、自動換行、等等，是一篇值得參考的文章，同時也見證ClosedXML的強大
