Привет, я пытаюсь сгруппировать ячейки на основе значений в столбце два , используя это для создания PDF с использованием apache FOP

Мой код

для определенного столбца мне нужно объединить повторяющиеся значения, чтобы, если 5000 повторяется в одном и том же столбце, мне нужно динамически объединять 5000 в одну ячейку на основе значения

Я также пытался с** xsl: for-each-group ** group-adj = = "column-two" , column-grouping-key () но это не группировка, как я ожидал,Пожалуйста, помогите, заранее спасибо.

Я думаю, что вы хотите использовать group-adjacent, а затем вам нужно передать количество элементов группы и текущий групповой индекс, чтобы заполнить атрибут number-rows-spanned и заблокировать вывод любой второй ячейки column-twoв соседней группе:
