极客教程jQWidgets jqxTreeGrid columnsReorder属性
jQWidgets是一个JavaScript框架，用于为PC和移动设备制作基于网络的应用程序。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。jqxTreeGrid用于以树状结构表示数据。这个部件对于显示分层数据的多列、数据分页、排序和过滤、数据编辑、列大小调整、固定列、条件格式化、聚合和行选择很有用。这些小组件还可以从任何类型的数据源中读取和显示数据，如XML、JSON、Array、CSV或TSV。
columnsReorder 属性用于设置或获取指定jqxTreeGrid的列的重新排序。这个属性接受布尔值。
语法:
- 用于设置columnsReorder属性。
$('#treeGrid').jqxTreeGrid({columnsReorder: true});
- 用于获取columnsReorder属性。
var columnsReorder = $('#treeGrid').jqxTreeGrid('columnsReorder');
