我有这个带分页的JSF表。

我创建了简单的行计数示例，只是为了用非常简单的html表来表示行的编号。在第二个表中，分页有效，但我不知道如何在ui:repeat中实现h:dataTable以实现行计数。我该如何实现呢？
答案 0 :(得分：6)
<h:dataTable binding="#{table}" ...>
<h:column>
#{table.rowIndex + SessionsController.firstRow + 1}
</h:column>
...
</h:dataTable>
答案 1 :(得分：0)
我不确定我是否理解正确。你只想要编号的行？
但是，我认为这并不像你想象的那么容易。 h：dataTable实际上不支持这个。混合h：dataTable和ui：repeat似乎是完全错误的方法（如果我理解正确的话）。
你可以：
使用t：dataTable（来自Tomahawk：http://myfaces.apache.org/tomahawk/index.html）。在那里你可以使用rowIndexVar属性，如下所示：
<t:dataTable rowIndexVar="row" value="#{someBean.value}">
<h:column>
<h:outputText value="#{row + 1}"/>
</h:column>
</t:dataTable>
另外，更改您的数据模型并在其中提供索引。或者使用包装类：
public class DataWrapper{
private int index;
private Object model;
// getter and setter
...
}
然后将DataWrapper列表传递给JSF，而不是直接传递给您的模型。当然，您需要首先在服务层的某处设置索引。
我希望这会有所帮助。如果您需要进一步的帮助，请与我们联系。
