DataTable介绍

[英]A data table builds on data grid view to introduce toolbars. Toolbars can be used to display sortable column headers, paging information, filter controls, and other information.

Data table also provides its own markup for an html table so the user does not need to provide it himself. This makes it very simple to add a datatable to the markup, however, some flexibility.

Example

<table wicket:id="datatable"></table>

And the related Java code: ( the first column will be sortable because its sort property is specified, the second column will not )

List<IColumn<T>> columns = new ArrayList<IColumn<T>>(); 
columns.add(new PropertyColumn(new Model<String>("First Name"), "name.first", "name.first")); 
columns.add(new PropertyColumn(new Model<String>("Last Name"), "name.last")); 
DataTable table = new DataTable("datatable", columns, new UserProvider(), 10); 
table.addBottomToolbar(new NavigationToolbar(table)); 
table.addTopToolbar(new HeadersToolbar(table, null)); 
add(table);

[中]数据表构建在数据网格视图上，以引入工具栏。工具栏可用于显示可排序列标题、分页信息、筛选器控件和其他信息。
数据表还为html表提供了自己的标记，因此用户无需自己提供。这使得向标记中添加数据表变得非常简单，但也有一定的灵活性。
实例

<table wicket:id="datatable"></table>

和相关的Java代码：（第一列将是可排序的，因为它的排序属性已指定，第二列将不会）

List<IColumn<T>> columns = new ArrayList<IColumn<T>>(); 
columns.add(new PropertyColumn(new Model<String>("First Name"), "name.first", "name.first")); 
columns.add(new PropertyColumn(new Model<String>("Last Name"), "name.last")); 
DataTable table = new DataTable("datatable", columns, new UserProvider(), 10); 
table.addBottomToolbar(new NavigationToolbar(table)); 
table.addTopToolbar(new HeadersToolbar(table, null)); 
add(table);
