    @JonB Sorry i don't understand can u explain about where i should do this: Change to a lambda for the slot which calls setCurrentIndex() before edit()?

        QObject::connect(ui->tableWidgetAdminEmployee, &QTableWidget::clicked,
                         ui->tableWidgetAdminEmployee, [=](const QModelIndex& index) {
            qDebug() << "In slot";
            ui->tableWidgetAdminEmployee->setCurrentIndex(index);
            qDebug() << "Calling edit()";
            ui->tableWidgetAdminEmployee->edit(index);
            qDebug() << "Called edit()";
            });
    

    Something like that (untested). I don't suppose doing setCurrentIndex(index) will solve your problem, but it's worth a try.

      @JonB Added, when i choose cell which is non-editable console writes:
      In slot
      Calling edit()
      edit: editing failed
      Called edit()

      When i choose editable cells console writes:
      In slot
      Calling edit()
      Called edit()

        What do you expect otherwise? I mean - it just tells you that a non-editable item can not be edited. So either life with it or don't call edit() on such an item.

          I did not realize you were doing this on the non-editable cells! So it is behaving well/as it should, what is the issue? Earlier you wrote:

          but when i click on enabled cell in console appears line "edit: editing failed"

          Now you show that works fine on editable cells.

              if (ui->tableWidgetAdminEmployee->itemFromIndex(index)->flags() & Qt::ItemIsEnabled )
                  ui->tableWidgetAdminEmployee->edit(index);
              

              Something like that.

                        QObject::connect(ui->tableWidgetAdminEmployee, &QTableWidget::clicked,
                                             ui->tableWidgetAdminEmployee, [=](const QModelIndex& index) {
                                ui->tableWidgetAdminEmployee->setCurrentIndex(index);
                                if (ui->tableWidgetAdminEmployee->itemFromIndex(index)->flags() & Qt::ItemIsEnabled )
                                    ui->tableWidgetAdminEmployee->edit(index);

                                  ui->tableWidgetAdminEmployee, [=](const QModelIndex& index) {
                        ui->tableWidgetAdminEmployee->setCurrentIndex(index);
                        if(index.column()!=0&&index.column()!=7&&index.column()!=8&&index.column()!=9)
                        if (ui->tableWidgetAdminEmployee->item(index.row(), index.column())->flags() & Qt::ItemIsEnabled )
                        ui->tableWidgetAdminEmployee->edit(index);
                        });
                        

                        But now after making some columns editable i can't make them non-editable

                          Change the flag of the item accordingly.

                                  To tell the truth, i don't understand what you're trying to do from the beginning.

                                    @mpergand I'm trying by pressing the button make editable some columns and make non-editable some columns in table, then after another button make all table non-editable.
                                    Also i can't disconnect, if i could i would just set table readonly

                                      QObject::connect(ui->tableWidgetAdminEmployee, &QTableWidget::clicked,

                                      Here you click on a table cell not on a button.
                                      So what button are you talking about ?

                                          @Kuji said in How to set QTableWidget editable with a few non-editable columns, and editing by one click on cell?:

                                          @mpergand this connection happens after pressing on usuall QPushButton

                                          Where do you make this connection, where is that button, outside or inside the table ?
                                          QObject::connect(ui->tableWidgetAdminEmployee, &QTableWidget::clicked,
                                          doesn't respond to a button click.
