Люди!!! Подскажите плиз , для чего в 3 версии нужны вертикальные бэнды и как с их помощью можно построить кросс-отчет? В доках по этой версии ничего не сказано об этом. И то как-то коряво смотрится DBCross с этим пустым местом в левом верхнем углу. Столбцы с данными подписаны, а строки - нет. Может кто подскажет решение проблемки ? ;)

    Для заполнения "вехнего-левого" CrossTab угла я использовал следующее.
    Все что я делал лежит в приделах LEFT_TOP_RECT

    Спасибо, друг! Но вот только как эту красоту применить? Я в fr новичок ведь. А что про вертикальные бенды скажешь? Мне кажется вещь интересная . ;) )

    Почитай документацию на версию 2.*. Там по-илему нормально написано, но имей в виду что, у этих отчетов есть один большой минус (он же является и большим плюсом)- ты САМ заполняешь текущую ячейку значением. Кроме этого в версии 2.* не было общего ИТОГО по всем столбцам. Приходилось считать вручную. В 3.* я их пока не использовал, пока хватает crossTab. Успехов!
