    @ManiRon This is not valid HTML.
    And by "code" I mean your C++ code to generate the HTML file...

          @ManiRon This is how a HTML document should look like:

          <html>
  <head>
   HEADER IF NEEDED 
  </head>
  <body>
    YOUR CONTENT HERE
  </body>
</html>

            Since you are hard coding stuff anyway, you can use QXmlStreamWriter directly on the QFile device to generate html:

            QFile qHtmlFile("myFile.html");
if(qHtmlFile.open(QIODevice::WriteOnly){
QTextStream startDocStream(&qHtmlFile);
startDocStream << QStringLiteral("<!DOCTYPE html>");
QXmlStreamWriter htmlWriter(&qHtmlFile);
htmlWriter.writeStartElement(QStringLiteral("html"));
htmlWriter.writeAttribute(QStringLiteral("xmlns"),QStringLiteral("http://www.w3.org/1999/xhtml"));
htmlWriter.writeAttribute(QStringLiteral("lang"),QStringLiteral("en"));
htmlWriter.writeAttribute(QStringLiteral("xml"),QStringLiteral("lang"),QStringLiteral("en"));
htmlWriter.writeStartElement(QStringLiteral("head"));
htmlWriter.writeStartElement(QStringLiteral("meta"));
htmlWriter.writeAttribute(QStringLiteral("http-equiv"),QStringLiteral("Content-Type"));
htmlWriter.writeAttribute(QStringLiteral("content"),QStringLiteral("text/html; charset=utf-8"));
htmlWriter.writeEndElement(); //meta
htmlWriter.writeStartElement(QStringLiteral("title"));
htmlWriter.writeCharacters(QStringLiteral("Test Page"));
htmlWriter.writeEndElement(); //title
htmlWriter.writeStartElement(QStringLiteral("style"));
htmlWriter.writeCharacters(QStringLiteral("h1, h2, h3, h4 { color: rgb(83,129,53) } h1 { text-align: center; }"));
htmlWriter.writeEndElement(); //style
htmlWriter.writeEndElement(); //head
htmlWriter.writeStartElement(QStringLiteral("body"));
htmlWriter.writeStartElement(QStringLiteral("h1"));
htmlWriter.writeCharacters(QStringLiteral("Test Page"));
htmlWriter.writeEndElement(); //h1
htmlWriter.writeStartElement(QStringLiteral("h2"));
htmlWriter.writeCharacters(QStringLiteral("Lorem"));
htmlWriter.writeEndElement(); //h2
htmlWriter.writeStartElement(QStringLiteral("p"));
htmlWriter.writeCharacters(QStringLiteral("Lorem ipsum dolor sit amet, consectetur adipiscing elit."));
htmlWriter.writeEndElement(); //p
htmlWriter.writeEndElement(); //body
htmlWriter.writeEndElement(); //html
}

              @jsulm I have not defined the html tag but still it was generating the html file correctly but when i removed the QTextbrowser , still it was generating correctly but the internal borders of the table is only the major missing.

                    Did you try to compare the HTML you generated with QTextBrowser and the one you are generating now ?
