Hi,
I've made a program with a JTable. The program imports some data
from internet in the JTable. The columnheaders are not blue, until
the import. After the import the headers are blue with a little
triangle next to the headerword. How does that come?
The program can also import from an offline file and with that
import the headers don't turn blue. (Don't know if that has
something to do with it.)

Sounds like you are hitting a bug in the Aqua table header renderer.
You will likely find that bringing up a JFileChooser sorted by date
(the second column), will cause other JTables in your app to render as
"selected", with offset text. This is an unfortunate side effect of
the JFileChooserUI not using a separate instance of the
apple.awt.AquaListHeaderBorder.
Please try Java SE 6 Developer Preview 5 at http://connect.apple.com,
and see if this issue reproduces for you.
As a workaround for J2SE 5.0 or J2SE 1.4, you can replaced the
TableCellRenderer for the column with a subclass of
DefaultTableCellRenderer that has the border set to a new instance of
AquaListHeaderBorder. You don't have to create a new instance for each
column or table, it just has to be a different instance than the
default one that is used by the JFileChooserUI.
Hope this helps,
