Группировка по значениям строки столбца в таблице xsl: fo - PullRequest
0 голосов
/ 29 октября 2019

Я пытаюсь сгруппировать значения отдельного столбца в xsl fo: table, некоторые значения не сгруппированы должным образом, оно группируется в соответствии с сгруппированным значением предыдущего столбца,

enter image description here

Мне нужна отдельная группировка по столбцам, проверьте с помощью моих файлов xsl и xml, я использую эти файлы для создания файла PDF с использованием apache FOP.

Я думаю, что один из способов решить эту проблему - использовать два прохода, один из которых вычисляет и добавляет диапазон строк к столбцам, а второй - с преобразованием в XSL-FO.

В https://xsltfiddle.liberty -development.net / 3NSSEuY / 2 Я использовал XSLT 3 и xsl:iterate для реализации первого шага для последовательности имен столбцов, предоставляемых в качестве параметра xs:string*:
