Hello,

Thanks for your inquiry.

Please try the following sample code for testing. I added some comments in the code, hope them can help you. If there is any other questions, just feel free to get back to us.

Code: Select all

            Document doc = new Document(true);
            doc.LoadFromFile("tableTest.docx");
            //Create a simple datatable
            DataTable dt = new DataTable();
            dt.Columns.Add("Name", typeof(string)); 
            dt.Columns.Add("Age", typeof(Int32));

            dt.Rows.Add("Andy", 99);
            dt.Rows.Add("Nina", 18);

            //Find the key word
            string key = "[#mytable]";

            TextSelection textSelection= doc.FindString(key,false,true);
            //Get the TextRange of the key word
            TextRange range=textSelection.GetAsOneRange();
            //Get it's parent Paragraph
            Paragraph parentPara = range.OwnerParagraph;

            int rangeIndex = parentPara.ChildObjects.IndexOf(range);
            //Create temp bookmark
            BookmarkStart start = new BookmarkStart(doc,"testBookmark");
            BookmarkEnd end = new BookmarkEnd(doc, "testBookmark");
            //Insert the start and end tags of the bookmark on either side of the key word.
            parentPara.ChildObjects.Insert(rangeIndex, start);
            parentPara.ChildObjects.Insert(rangeIndex+2,end);
            //Locate the bookmark.
            BookmarksNavigator navigator = new BookmarksNavigator(doc);
            navigator.MoveToBookmark("testBookmark");
            //Create a object of Spire.Doc.Table
            Table table = new Table(doc);
            //Reset the rows and columns based on the datatable
            table.ResetCells(dt.Rows.Count+1, dt.Columns.Count);

            //Fill header row
            int i = 0;
            foreach(DataColumn dataColumn in dt.Columns){
                table[0, i++].AddParagraph().AppendText(dataColumn.ColumnName);
            }
            //Fill data rows
            for (i = 0; i < dt.Rows.Count; i++)
            {
                DataRow row = dt.Rows[i];
                for(int j = 0; j < row.ItemArray.Length; j++)
                {
                    table[i + 1, j].AddParagraph().AppendText(row.ItemArray[j].ToString());
                }
            }
            //Create a body to contains the table
            TextBodyPart body = new TextBodyPart(doc);
            body.BodyItems.Add(table);
            //Replace the whole body between the bookmark tags using the new body
            navigator.ReplaceBookmarkContent(body);
            //Remove the temp bookmark
            doc.Bookmarks.Remove(navigator.CurrentBookmark);
            //Save the file to disk
            doc.SaveToFile("output.docx",FileFormat.Docx);
