当我开始为我的JSF应用程序转换此代码时，我发现我可以使用< h：dataTable> 或< h：panelGrid> 因为两者都在此作为 html中的表格。首先我要问的是我应该在这里使用什么？

2怎样才能处理< thead> ，< tfoot> 和< tbody> 因为我没有找到他们的在JSF中备用。所以请任何人都可以付出一些努力来帮助我。谢谢

When I started to convert this code for my JSF app I found that I can use either <h:dataTable> or <h:panelGrid> because both are use here as an alternative of table in html.So first thing which I want to ask is what should I use here?
2ndly how can I handle <thead> , <tfoot> and <tbody>as I didn't find their alternate in JSF.So please can anyone put some effort to help me for this
Thanks

推荐答案

<$ c $如果您（在您的支持bean中）有一组需要显示的对象，则c>< h：dataTable> 是一个不错的选择。例如，如果你有一个对象员工列表（包括Id，Name，Surname等），那么这是最好的选择。

<h:dataTable> is a good choice if you have (in your backing bean) a set of objects you need to display. For example if you have a List of object Employee (with Id, Name, Surname, etc.) then is the best choice.

在这里你可以找到一个例子< a href =http://www.javabeat.net/2008/04/hdatatable-java-server-faces-jsf/ =nofollow noreferrer>如何使用dataTable 。

Here you can find an example of how to use dataTable.

< h：panelGrid> 是一个不错的选择，如果您以某种方式布局各种元素。一种情况是，当你必须将空间分成两列，分别为80％和20％时。
虽然'我'建议使用（panelGroup）用于此目的，但请参阅 http ：//www.w3.org/2002/03/csslayout-howto

<h:panelGrid> is a good choice if you have layout various elements in an certain way. One case, is when you have to split the space in two columns of 80% and 20% respectively. Though, 'I' suggest to use (panelGroup) for this purpose see http://www.w3.org/2002/03/csslayout-howto

编辑： 使用< h：dataTable> 对于页眉，页脚等，您必须使用标签< f：facet />
请参阅 JSF中的多个页脚行dataTable

With the <h:dataTable> For the header, footer, etc. you have to use the tag <f:facet /> see Multiple Footer Rows in a JSF dataTable
