VS/TFS 2010: How to set Indent and Outdent

Task query 默认情况下是看不到Indent和Outdent的：

如果我们想要使用Indent和Outdent功能，该如何操作呢？

1. Right click one query, such as My Work Items, then click Edit Query

2. In the Type of Query, select Tree of Work Items, click Save Query

3. Indent and Outdent Icons are show, and hierarchies work items

Thanks
