Here are the limits to what you can do with the files panel:
You can move the individual columns to wherever you want them, simply by clicking on them and dragging them with the mouse. Also you can alter the priority in which a column displays - which ever column you do this for will take priority for the entire list until you do the same thing with another column. The list of columns that is actually displayed can be made visible by right-clicking on any column name - you get a list like this:

If it's in that list, you can choose whether to display it or not, and as I mentioned, you can drag the list order around to have the columns where you want them. If what you want isn't in that list, then I'm afraid you're out of luck!
