C#操作word之插入表格
假如我们需要在一个word文档的某个位置插入一张表格，而且要对这一张表格中的单元格做拆分合并，之类的。
先看下效果，先不管表格是否合理，总之就是要这样的统计文档，但是人数，班级数都是不确定的，也就是表格是根 据数据动态生成的，
这样我们就很难用之前的替换方式来实现，也就是要动态来创建表格。
班级成绩统计单
| 班级 | 姓名 | 成绩 | 人数总计 | 班主任 |
| 一班 | 张三 | 498 | 1 | 小李 |
| 二班 | 李四 | 354 | 2 | 陈飞 |
| 小红 | 502 | |||
| 三班 | 丁爽 | 566 | 1 | 王林 |
1、用单元格拆分的方式实现，也就是根据有多少班级，则增加多少行，针对于其中的学生信息再对单元格进行拆分。
/// <summary> /// 数据实体类 /// </summary> public class Student { public string Name;//姓名 public int Score;//成绩 public string StuClass;//班级 public string Leader;//班主任 } /// <summary> /// 动态创建table到word /// </summary> protected void CreateTableToExcel() { Word.Application app = null; Word.Document doc = null; try { //构造数据 List<Student> datas = new List<Student>(); datas.Add(new Student{ Leader="小李", Name="张三", Score=498, StuClass="一班"}); datas.Add(new Student{ Leader="陈飞", Name="李四", Score=354, StuClass="二班"}); datas.Add(new Student{ Leader="陈飞", Name="小红", 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;//表格行数加1是为了标题栏 int cols = 5;//表格列数 object oMissing = System.Reflection.Missing.Value; app = new Word.Application();//创建word应用程序 doc = app.Documents.Add();//添加一个word文档 //输出大标题加粗加大字号水平居中 app.Selection.Font.Bold = 700; app.Selection.Font.Size = 16; app.Selection.Range.ParagraphFormat.Alignment = Word.WdParagraphAlignment.wdAlignParagraphCenter; app.Selection.Text = "班级成绩统计单"; //换行添加表格 object line = Word.WdUnits.wdLine; app.Selection.MoveDown(ref line, oMissing, oMissing); app.Selection.TypeParagraph();//换行 Word.Range range = app.Selection.Range; Word.Table table = app.Selection.Tables.Add(range, rows, cols, ref oMissing, ref oMissing); //设置表格的字体大小粗细 table.Range.Font.Size = 10; table.Range.Font.Bold=0; //设置表格标题 int rowIndex = 1; table.Cell(rowIndex, 1).Range.Text = "班级"; table.Cell(rowIndex, 2).Range.Text = "姓名"; table.Cell(rowIndex, 3).Range.Text = "成绩"; table.Cell(rowIndex, 4).Range.Text = "人数"; table.Cell(rowIndex, 5).Range.Text = "班主任"; //循环数据创建数据行 rowIndex++; foreach (var i in cate) { table.Cell(rowIndex, 1).Range.Text = i.Key;//班级 table.Cell(rowIndex, 4).Range.Text = i.Count().ToString();//人数 table.Cell(rowIndex, 5).Range.Text = i.First().Leader;//班主任 table.Cell(rowIndex,2).Split(i.Count(), 1);//分割名字单元格 table.Cell(rowIndex,3).Split(i.Count(), 1);//分割成绩单元格 //对表格中的班级、姓名，成绩单元格设置上下居中 table.Cell(rowIndex, 1).VerticalAlignment = Word.WdCellVerticalAlignment.wdCellAlignVerticalCenter; table.Cell(rowIndex, 4).VerticalAlignment = Word.WdCellVerticalAlignment.wdCellAlignVerticalCenter; table.Cell(rowIndex, 5).VerticalAlignment = Word.WdCellVerticalAlignment.wdCellAlignVerticalCenter; //构建姓名，成绩数据 foreach (var x in i) { table.Cell(rowIndex, 2).Range.Text = x.Name; table.Cell(rowIndex, 3).Range.Text = x.Score.ToString(); rowIndex++; } } //导出到文件 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();//关闭文档 } if (app != null) { app.Quit();//退出应用程序 } } }
2、单元格合并的方式，即循环数据输出，然后对班级，人数，班主任列进行合并，但是合并的时候需要注意，假如某班级只有一个同学，也就是其实不需要合并的，
则必须排除在外，否则会出现”此命令无效“的异常，所以下面代码在合并的时候做了一个判断。
protected void CreateTableToExcel2() { Word.Application app = null; Word.Document doc = null; try { //构造数据 List<Student> datas = new List<Student>(); datas.Add(new Student { Leader = "小李", Name = "张三", Score = 498, StuClass = "一班" }); datas.Add(new Student { Leader = "陈飞", Name = "李四", Score = 354, StuClass = "二班" }); datas.Add(new Student { Leader = "陈飞", Name = "小红", 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;//表格列数 object oMissing = System.Reflection.Missing.Value; app = new Word.Application();//创建word应用程序 doc = app.Documents.Add();//添加一个word文档 //输出大标题加粗加大字号水平居中 app.Selection.Font.Bold = 700; app.Selection.Font.Size = 16; app.Selection.Range.ParagraphFormat.Alignment = Word.WdParagraphAlignment.wdAlignParagraphCenter; app.Selection.Text = "班级成绩统计单"; //换行添加表格 object line = Word.WdUnits.wdLine; app.Selection.MoveDown(ref line, oMissing, oMissing); app.Selection.TypeParagraph();//换行 Word.Range range = app.Selection.Range; Word.Table table = app.Selection.Tables.Add(range, rows, cols, ref oMissing, ref oMissing); //设置表格的字体大小粗细 table.Range.Font.Size = 10; table.Range.Font.Bold = 0; //设置表格标题 int rowIndex = 1; table.Cell(rowIndex, 1).Range.Text = "班级"; table.Cell(rowIndex, 2).Range.Text = "姓名"; table.Cell(rowIndex, 3).Range.Text = "成绩"; table.Cell(rowIndex, 4).Range.Text = "人数"; table.Cell(rowIndex, 5).Range.Text = "班主任"; //循环数据创建数据行 rowIndex++; foreach (var i in cate) { int moveCount = i.Count() - 1;//纵向合并行数 if (moveCount.ToString() != "0") { table.Cell(rowIndex, 1).Merge(table.Cell(rowIndex + moveCount, 1));//合并班级 table.Cell(rowIndex, 4).Merge(table.Cell(rowIndex + moveCount, 4));//合并人数 table.Cell(rowIndex, 5).Merge(table.Cell(rowIndex + moveCount, 5));//合并班主任 } //写入合并的数据并垂直居中 table.Cell(rowIndex, 1).Range.Text = i.Key; table.Cell(rowIndex, 4).Range.Text = i.Count().ToString(); table.Cell(rowIndex, 5).Range.Text = i.First().Leader; table.Cell(rowIndex, 1).VerticalAlignment = Word.WdCellVerticalAlignment.wdCellAlignVerticalCenter; table.Cell(rowIndex, 4).VerticalAlignment = Word.WdCellVerticalAlignment.wdCellAlignVerticalCenter; table.Cell(rowIndex, 5).VerticalAlignment = Word.WdCellVerticalAlignment.wdCellAlignVerticalCenter; //构建姓名，成绩数据 foreach (var x in i) { table.Cell(rowIndex, 2).Range.Text = x.Name; table.Cell(rowIndex, 3).Range.Text = x.Score.ToString(); rowIndex++; } } //导出到文件 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();//关闭文档 } if (app != null) { app.Quit();//退出应用程序 } } }
