JSF 1.2 dataTable动态添加列

标签： jsp datatable jsf-1.2

所以我有一个页面要求用户输入我将用于在数据库中进行搜索的人员信息，以获得更强大的人口统计信息。我遇到的问题是，当然后在搜索中添加要查找的人（通过a）我将新行添加到列。

用户说他们不想垂直渲染数组。他们想要水平渲染，这意味着每个父对象都有一个新列。并且只有父母如此，如果addRow对他们来说工作正常，那么他们想要并排比较。我迷失了如何通过jsf / jsp这样做。这是我现在拥有的：

因此，如果您想要动态地向您的dataTable添加列，您可以通过两种方式执行此操作，binding your dataTable使用第三方组件库（如支持bean OR RichFaces ，您可以使用powered data tables来定义columns标记以动态创建它们。选择其中一个，集成Richfaces意味着将相应的库添加到类路径并进行配置。
