The palette defines only the "attributes" that you might use. But defining
a palette doesn't mean that those attributes are applied to anything. You
have to apply the attributes to the widgets manually using AttrWrap:
wrapped_widget = AttrWrap(my_widget, "my_attribute")
Widgets without their own attribute are rendered with the attribute of
the widget containing them (if any, otherwise with the default colours of
the terminal).
Try the attached program!

The ListBox is great! :)
For my "table", I used a Columns widgets with each column containing a
ListBox widget. So in your case that would be one ListBox with the filenames
in the first column, one ListBox with the according file sizes in the second
column etc. This approach gets a little tricky if you want rows of this table
to be selectable only as a whole, but I could post a stand alone version of the
Table widget I am using in the unicore configuration stuff, if you are
interested.
