极客教程jQWidgets jqxDataTable aggregatesHeight属性
jQWidgets是一个JavaScript框架，用于为PC和移动设备制作基于Web的应用程序。它是一个非常强大的、优化的、与平台无关的、并被广泛支持的框架。jqxDataTable是用来读取和显示HTML表的数据的。这也被用来显示来自各种数据源的数据，如XML、JSON、Array、CSV或TSV。
aggregatesHeight 属性用于设置或获取指定jqxDataTable的聚合条的高度。这个属性只有在showAggregates属性的值被设置为true时才会有效。
语法:
用于设置aggregatesHeigh t属性。
$('Selector').jqxDataTable({aggregatesHeight: 30});
用于获取aggregatesHeight属性。
var aggrHeight = $('Selector').jqxDataTable('aggregatesHeight');
