    @HenkCoder said in How to style a table in QTextEdit:

    edit->document()->setDefaultStyleSheet("QTextDocument:table{width: 100%; border-collapse: collapse}");

    Do you still get the same result if you leave off 'QTextDocument'? I think it is expecting a purely CSS stylesheet, not QSS.

      @mchinand Yep, I tried and it's still the same.

        Hello,
        How do I change the stylesheet to a table that I insert in the QTextEdit?
        I've read this article: https://www.w3schools.com/Css/css_table.asp but edit->setStyleSheet("QTextEdit:table{border-collapse: collapse;}"); doesn't seem to work.
        Is there a way I can achieve this?
        Thanks.

        QTextDocument:table{width: 100%; border-collapse: collapse}

        You may know more than I, but where did you get that QTextEdit:table (or QTextDocument:table) syntax from?

          Can you share a minimal full project that has your current code for applying a stylesheet to a QTextDocument?

              Hello, I didn't find anywhere that code, I just wrote that because in all of the other style sheet that I've used the syntax was like this but I don't knoe.

                I meant your current code. Post it here. Not just the single line calling setDefaultStyleSheet().

                  That's not a very good start. If you don't know whether the selector works it doesn't matter what you write inside it.

                  Apart from the fact that Qt documents what subset it uses, what CSS /"all of the other style sheet that I've used" uses the : where you do? (Other than a few pseudo-selectors like a:link, which is quite different from your case.)

                            edit->setTextBackgroundColor(QColor(backRed, backGreen, backBlue));
                        edit->setFontPointSize(fontSize);
                        edit->document()->setDefaultStyleSheet("QTextDocument:table{width: 100%; border-collapse: collapse;}");
                        edit->setFontFamily(fontName);
                        ui->fontComboBox->setCurrentFont(QFont(fontName));
                        ui->fontsize->setValue(fontSize);
                        QObject::connect(edit, &TextEdit::textChanged, this, &MainWindow::edit_changed);
                        QObject::connect(edit, &TextEdit::cursorPositionChanged, this, &MainWindow::cursorPosChanged);
                    
                    

                    Do you want the full constructor code?

                      My bad sorry, I used a few times :: for example in the tabWidget one.
                      QTabWidget::tab I tried again with that but it still doesn't work.

                        Where's your table? Did you see this comment regarding the defaultStyleSheet?

                        "Note: Changing the default style sheet does not have any effect to the existing content of the document."

                            Have you tried plain setDefaultStyleSheet/setStylesheet("table{width: 100%; border-collapse: collapse;}") on something?

                                Try just creating a table statically in code first to figure out how to get the stylesheet working.

                                    Hi,

                                    I think you are mixing two very different things here:

                                    • Qt Style Sheet for customizing widgets
                                    • QTextDocument Rich Text support shown through QTextEdit.

                                    What you want to do is handled by the later. See the Rich Text chapter in Qt's documentation.

                                      Hi,

                                      I think you are mixing two very different things here:

                                      • Qt Style Sheet for customizing widgets
                                      • QTextDocument Rich Text support shown through QTextEdit.

                                      What you want to do is handled by the later. See the Rich Text chapter in Qt's documentation.

                                      @SGaist Hello,
                                      So, I got the border collapse working by doing this:

                                      TextEdit *edit{getTabTextEdit()};
                                          QTextTableFormat format;
                                          format.setBorderCollapse(true);
                                          edit->textCursor().insertTable(lineNum, columnNum, format);
                                      

                                      But I don't know how to set the table's width to change when the textedit's width changes and I don't know how to put its width to 100% as CSS does.

                                        If memory serves well, something like:

                                        format.setWidth(QTextLength(QTextLength::PercentageLength, 100));

                                          @SGaist Yes! This was right!
                                          Thank you so much, but I have one last question, sorry about that.
                                          When I create the table it's like this:
                                          2ee25edf-65b3-4cb4-b708-c72fc795898b-image.png
                                          but then when I type something in a cell the line separing the different cells adapts to the text. How do I avoid that?
                                          1028cb6d-ea87-49a6-a923-5f6d7e1adbb7-image.png
                                          I just wanted to expand the table to the TextEdit's width not also this feature.
