with the instruction :
NodeImporter importer = new NodeImporter(srcDoc, dstDoc, ImportFormatMode.KeepSourceFormatting);
NodeImporter importer = new NodeImporter(srcDoc, dstDoc, ImportFormatMode.KeepSourceFormatting);
Node currentSession = (Section)originalStartNode.GetAncestor(NodeType.Section);
Node cloneSess = currentSession.Clone(false);
cloneSess = importer.ImportNode(cloneSess, true);
((Section)cloneSess).AppendChild(new Body(dstDoc));
dstDoc.AppendChild(cloneSess);
used for copy word document in other document,
the copied word table loses the styles, particularly if there are lines highlighted alternately, the style of the lines is lost
