                        //插入Table单元格
                        builder.InsertCell();

                        //Table单元格边框线样式
                        builder.CellFormat.Borders.LineStyle = LineStyle.Single;

                        //Table此单元格宽度 跟随列头宽度
                        //builder.CellFormat.Width = 500;

                        //此单元格中内容垂直对齐方式
                        builder.CellFormat.VerticalAlignment = Aspose.Words.Tables.CellVerticalAlignment.Center;

                        builder.CellFormat.HorizontalMerge = Aspose.Words.Tables.CellMerge.None;
                        builder.CellFormat.VerticalMerge = Aspose.Words.Tables.CellMerge.None;

                        //字体大小
                        builder.Font.Size = 10;

                        //是否加粗
                        builder.Bold = false;

                        //向此单元格中添加内容
                        builder.Write(str);

                    }

                    //Table行结束
                    builder.EndRow();

                }
                builder.EndTable();
            }
            else
            {//其他文字,日期等文字
                bm.Text = "";
                builder.MoveToBookmark(bookMark);
                bm.Text =@value;
            }

        }

    }
}

调用:

        private void button2_Click(object sender, EventArgs e)
        {
            Aspose.Words.Document doc = new Aspose.Words.Document("TEMPLATE.DOCX");
            Aspose.Words.DocumentBuilder builder = new Aspose.Words.DocumentBuilder(doc);

            //在书签处插入表格
            Utils.AsposeWordReplaceBookMarkContentApi.BookMarkReplace(doc, builder, "BK002", "TABLE", "[{'Name':'zhangsan','Sex':'Male'},{'Name':'wangwu','Sex':'Female'}]");
            //在书签处插入图片
            Utils.AsposeWordReplaceBookMarkContentApi.BookMarkReplace(doc, builder, "BK001", "IMG", "1.PNG");
            //在书签处插入文字
            Utils.AsposeWordReplaceBookMarkContentApi.BookMarkReplace(doc, builder, "BK003", "TEXT", "  测试文字啊啊涉及到法律框架阿斯兰开发按时交电费卡拉斯几发,阿斯顿减肥拉斯加付款阿卡丽交电费卡拉斯发的,看到谁放假啦设计费看,开始搭建费绿卡是否看见快乐健康了阿斯顿发顺丰空间看拉丁方.");

            string saveDocFile = "1.DOCX";
            doc.Save(saveDocFile);

            if (MessageBox.Show("保存成功，是否打开文件？", "", MessageBoxButtons.YesNo) == System.Windows.Forms.DialogResult.Yes)
            {
                System.Diagnostics.Process.Start(saveDocFile);
            }
        }

效果:

打印

doc.Print();

文本替换

doc.Range.Replace("{{name}}", "张三", false, true);
