Columns in analysis detail preview don't sort

In the detailed results of an analysis, the Description and Size column labels depress (when clicked) as if clicking them is supposed to do something, but it doesn't. In contrast, the column labels in the Tools > Uninstall table depress in the same way and do serve to sort the table. I'm still too new to Mac to recognize whether, e.g., those are standard Cocoa-provided tables (and column headers) and the depression behavior is enabled by default or can't be disabled, or whatever. In other words I don't know whether to take the depression behavior as a sign that the developers intend for those columns to be sortable, in which case this would be a bug report. (I'm guessing not.) If they currently don't intend for them to be sortable, consider this a request that they do. :)
