Word file containing a table with merged rows


The attached Word document contains a table with multiple merged rows and columns. The following Java 8 code converts this document into HTML.

FileInputStream fileInputStream = new FileInputStream(file); //
HWPFDocumentCore wordDocument = AbstractWordUtils.loadDoc(fileInputStream);
WordToHtmlConverter wordToHtmlConverter = new WordToHtmlConverter(DocumentBuilderFactory.newInstance().newDocumentBuilder().newDocument());
Document htmlDocument = wordToHtmlConverter.getDocument();
ByteArrayOutputStream out = new ByteArrayOutputStream();
DOMSource domSource = new DOMSource(htmlDocument);
StreamResult streamResult = new StreamResult(out);

TransformerFactory tf = TransformerFactory.newInstance();
Transformer serializer = tf.newTransformer();
serializer.setOutputProperty(OutputKeys.ENCODING, "UTF-8");
serializer.setOutputProperty(OutputKeys.INDENT, "yes");
serializer.setOutputProperty(OutputKeys.METHOD, "html");
serializer.transform(domSource, streamResult);

System.out.println(new String(out.toByteArray(), StandardCharsets.UTF_8));

In the generated HTML (see attached HTML), the "td" element corresponding to the lower right table cell contains a "rowspan" attribute with a value of "8" but this value should be "9" according to the original table layout.
