C#操作word之插入表格

假如我們需要在一個word文檔的某個位置插入一張表格，而且要對這一張表格中的單元格做拆分合並，之類的。

先看下效果，先不管表格是否合理，總之就是要這樣的統計文檔，但是人數，班級數都是不確定的，也就是表格是根 據數據動態生成的，

這樣我們就很難用之前的替換方式來實現，也就是要動態來創建表格。

                                                                                             班級成績統計單

班級	姓名	成績	人數總計	班主任
一班	張三	498	1	小李
二班	李四	354	2	陳飛
	小紅	502
三班	丁爽	566	1	王林

1、用單元格拆分的方式實現，也就是根據有多少班級，則增加多少行，針對於其中的學生信息再對單元格進行拆分。

 /// <summary>
        /// 數據實體類
        /// </summary>
        public class Student
        {
            public string Name;//姓名
            public int Score;//成績
            public string StuClass;//班級
            public string Leader;//班主任
        } 
        /// <summary>
        /// 動態創建table到word
        /// </summary>

        {
            Word.Application app = null;
            Word.Document doc = null;
            try
            {   
                //構造數據
                List<Student> datas = new List<Student>();
                datas.Add(new Student{ Leader="小李", Name="張三", Score=498, StuClass="一班"});
                datas.Add(new Student{ Leader="陳飛", Name="李四", Score=354, StuClass="二班"});
                datas.Add(new Student{ Leader="陳飛", Name="小紅", Score=502, StuClass="二班"});
                datas.Add(new Student{ Leader="王林", Name="丁爽", Score=566, StuClass="三班"});
                var cate = datas.GroupBy(s=>s.StuClass);

                int rows = cate.Count()+1;//表格行數加1是為了標題欄
                int cols = 5;//表格列數
                object oMissing = System.Reflection.Missing.Value;
                app = new Word.Application();//創建word應用程序
                doc = app.Documents.Add();//添加一個word文檔

                //輸出大標題加粗加大字號水平居中
                app.Selection.Font.Bold = 700;
                app.Selection.Font.Size = 16;

                Word.Range range = app.Selection.Range;
                Word.Table table = app.Selection.Tables.Add(range, rows, cols, ref oMissing, ref oMissing);

                //設置表格的字體大小粗細
                table.Range.Font.Size = 10;
                table.Range.Font.Bold=0;

                //設置表格標題
                int rowIndex = 1;
                table.Cell(rowIndex, 1).Range.Text = "班級";
                table.Cell(rowIndex, 2).Range.Text = "姓名";
                table.Cell(rowIndex, 3).Range.Text = "成績";
                table.Cell(rowIndex, 4).Range.Text = "人數";
                table.Cell(rowIndex, 5).Range.Text = "班主任";

                //循環數據創建數據行
                rowIndex++;
                foreach (var i in cate)
                {
                    table.Cell(rowIndex, 1).Range.Text = i.Key;//班級
                    table.Cell(rowIndex, 4).Range.Text = i.Count().ToString();//人數
                    table.Cell(rowIndex, 5).Range.Text = i.First().Leader;//班主任
                    table.Cell(rowIndex,2).Split(i.Count(), 1);//分割名字單元格
                    table.Cell(rowIndex,3).Split(i.Count(), 1);//分割成績單元格

                    //對表格中的班級、姓名，成績單元格設置上下居中
                    table.Cell(rowIndex, 1).VerticalAlignment = Word.WdCellVerticalAlignment.wdCellAlignVerticalCenter;
                    table.Cell(rowIndex, 4).VerticalAlignment = Word.WdCellVerticalAlignment.wdCellAlignVerticalCenter;
                    table.Cell(rowIndex, 5).VerticalAlignment = Word.WdCellVerticalAlignment.wdCellAlignVerticalCenter;

                    //構建姓名，成績數據
                    foreach (var x in i)
                    {
                        table.Cell(rowIndex, 2).Range.Text = x.Name;
                        table.Cell(rowIndex, 3).Range.Text = x.Score.ToString();
                        rowIndex++;
                    }
                }

                //導出到文件
                string newFile = DateTime.Now.ToString("yyyyMMddHHmmssss") + ".doc";
                string physicNewFile = Server.MapPath(newFile);
                doc.SaveAs(physicNewFile,
                oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing,
                oMissing, oMissing, oMissing, oMissing, oMissing, oMissing);
            }
            catch(Exception ex)
            {
            }
            finally
            {
                if (doc != null)
                {
                    doc.Close();//關閉文檔
                }
                if (app != null)
                {
                    app.Quit();//退出應用程序
                }
            }          
        }

 2、單元格合並的方式，即循環數據輸出，然后對班級，人數，班主任列進行合並，但是合並的時候需要注意，假如某班級只有一個同學，也就是其實不需要合並的，

則必須排除在外，否則會出現”此命令無效“的異常，所以下面代碼在合並的時候做了一個判斷。

protected void CreateTableToExcel2()
        {
            Word.Application app = null;
            Word.Document doc = null;
            try
            {
                //構造數據
                List<Student> datas = new List<Student>();
                datas.Add(new Student { Leader = "小李", Name = "張三", Score = 498, StuClass = "一班" });
                datas.Add(new Student { Leader = "陳飛", Name = "李四", Score = 354, StuClass = "二班" });
                datas.Add(new Student { Leader = "陳飛", Name = "小紅", Score = 502, StuClass = "二班" });
                datas.Add(new Student { Leader = "王林", Name = "丁爽", Score = 566, StuClass = "三班" });
                var cate = datas.GroupBy(s => s.StuClass);

                int rows = datas.Count + 1;
                int cols = 5;//表格列數
                object oMissing = System.Reflection.Missing.Value;
                app = new Word.Application();//創建word應用程序
                doc = app.Documents.Add();//添加一個word文檔

                //輸出大標題加粗加大字號水平居中
                app.Selection.Font.Bold = 700;
                app.Selection.Font.Size = 16;
                app.Selection.Range.ParagraphFormat.Alignment = Word.WdParagraphAlignment.wdAlignParagraphCenter;
                app.Selection.Text = "班級成績統計單";

                //換行添加表格
                object line = Word.WdUnits.wdLine;
                app.Selection.MoveDown(ref line, oMissing, oMissing);
                app.Selection.TypeParagraph();//換行
                Word.Range range = app.Selection.Range;
                Word.Table table = app.Selection.Tables.Add(range, rows, cols, ref oMissing, ref oMissing);

                //設置表格的字體大小粗細
                table.Range.Font.Size = 10;
                table.Range.Font.Bold = 0;

                //設置表格標題
                int rowIndex = 1;
                table.Cell(rowIndex, 1).Range.Text = "班級";
                table.Cell(rowIndex, 2).Range.Text = "姓名";
                table.Cell(rowIndex, 3).Range.Text = "成績";
                table.Cell(rowIndex, 4).Range.Text = "人數";
                table.Cell(rowIndex, 5).Range.Text = "班主任";

                //循環數據創建數據行
                rowIndex++;
                foreach (var i in cate)
                {
                    int moveCount = i.Count() - 1;//縱向合並行數
                    if (moveCount.ToString() != "0")
                    {
                        table.Cell(rowIndex, 1).Merge(table.Cell(rowIndex + moveCount, 1));//合並班級
                        table.Cell(rowIndex, 4).Merge(table.Cell(rowIndex + moveCount, 4));//合並人數
                        table.Cell(rowIndex, 5).Merge(table.Cell(rowIndex + moveCount, 5));//合並班主任
                    }
                    //寫入合並的數據並垂直居中
                    table.Cell(rowIndex, 1).Range.Text = i.Key;
