Hello ，In HTML, the display:none property is used to hide table columns. When converting HTML to Word using Aspose.Words, the table styling becomes misaligned
Code is as follows
public byte[] htmlForByte(String downloadHtml,String docType,String pictureIdsJson,String processInstanceId,String[] pictureIds) {
this.getLicense();
Document doc = null;
byte[] byteArray = null;
ByteArrayOutputStream docout = null;
try {
doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
