想象一下由 CListView 呈现的一个简单的新闻项目列表。每个新闻项都有一个“insertDate”属性，我可以通过 $data->insertDate 访问它。现在，这样的列表看起来像这样呈现：
// example (how list is displayed now)
9-18-2012 - Stocks fell for 2nd week
9-18-2012 - Record heat for 2012
9-18-2012 - Crime down in the state
9-17-2012 - Stock woes are worrying investors
9-17-2012 - Business outlook is optimistic despite slow growth
9-16-2012 - More people moving into big cities
9-16-2012 - Stay ahead of the flu this year
我想要做的是在当天的所有项目上方显示一个日期标题，以便显示看起来更像这样（下图）。有没有办法调整 CListView 来做到这一点？
