Свойство jQWidgets jqxDataTable autoRowHeight

Опубликовано: 3 Января, 2023

jQWidgets — это JavaScript-фреймворк для создания веб-приложений для ПК и мобильных устройств. Это очень мощная, оптимизированная, независимая от платформы и широко поддерживаемая платформа. jqxDataTable используется для чтения и отображения данных из таблицы HTML. Это также используется для отображения данных из различных источников данных, таких как XML, JSON, Array, CSV или TSV.

Свойство autoRowHeight используется для установки или возврата, если отображаемая таблица jqxDataTable спонтанно оценивает высоту строк, а также закрывает текст ячейки. Это логический тип, и его значение по умолчанию равно true.

Синтаксис:

Установите свойство autoRowHeight :

$("Selector").jqxDataTable({ autoRowHeight: false });

Вернуть свойство autoRowHeight :

var autoRowHeight = $("Selector").jqxDataTable("autoRowHeight");
