    I need HTML examples, not rich text

    The rich text examples are HTML4 examples.

    There is no use of HTML in it

              @duncan98 I suggest you first take a look at HTML documentation: https://www.w3schools.com/html/

                  You claimed that the rich text examples don't use HTML.

                  I showed you that the Text Edit Rich Text example uses HTML.

                    @duncan98 There is no "qt HTML". Qt supports a subset of HTML as @JKSH already pointed out...

                      I have done HTML for many, many years, so I know it too. What is your actual issue with the subset of HTML supported by Qt, e.g. in a QTextEdit?

                      You can copy the whole of the HTML content from the https://code.qt.io/cgit/qt/qtbase.git/tree/examples/widgets/richtext/textedit/example.html?h=5.14 example you refer to as a "mess", and as well as pasting it into a QTextEdit to look at it you can also save it to an .html file and open it in your web browser. Since it looks pretty similar there, you know it must be reasonably close to HTML. You can use the browser's F12 or your favorite HTML editor to examine the HTML.

                          What is your question? You can print from a QTextDocument. It supports precisely the HTML subset we have referenced above. If your content fits into that subset it will work, if your content goes beyond that into non-supported HTML constructs it will not (probably just ignore them). That's just how it is.

                          If you want full HTML support you would need to move to using QtWebEngine. You can print from there too, which would then support full HTML. You can arrange for the content of a QTextDocument to go into a QWebEnginePage if desired. But your original QTextDocument is still liable to be limited to the Qt-supported richtext-HTML subset.

                                  Your first decision is whether you want to print as a QTableWidget, with how that appears, or whether you want to export its content to a QTextDocument and print as a generic table. I have done both.

                                        What about the accepted solution in https://stackoverflow.com/questions/45467942/how-can-i-print-a-qwidget-in-qt ? The point is QWidget::render() to a painter/paint device which is the desired QPrinter. See https://doc.qt.io/qt-5/qtprintsupport-index.html#printing-widgets.

                                        If you decide you want to do it by generating an HTML document into a QDocument off the QTableWidget after all, see alternatively e.g. https://stackoverflow.com/questions/56605601/using-qt5-how-can-i-print-a-qtablewidget-and-scale-a-table-to-fit-onto-one-side. I went for this approach off any QTableView/model with rows & columns myself, so it's generic, I can use stylesheets for printing, I can export to PDF/CSV/XLSX, etc. One issue about printing the QTableWidget as-is is that you get e.g. the column widths/truncation etc. you see on the screen, which may not be desirable, depending on your usage.
