    1. COThank you! This is exactly what I was looking for and then some. You even through in a custom sorting icon just for fun:) (The Nimbus Default is fine, but thanks anyway.) Nice example to illustrate what is possible.

    2. COglad to help you, notice I'm still not sure, if you'll need to do the same things for TableCellEditor :-)

    3. COI would need to do the same things with TableCellEditor if I want the focus color to remain while editing. At this point, I completely understand HOW to do this, what's left is the decision of exactly WHAT do to. TableCellEditor explains why after the user starts editing a focused cell, the look changes (from the selected row color to a white background). That's probably what I want-I'm not sure it matters much. This question wasn't really about appearance, it was about making the table more intuitive and usable since some of my users are, let's say not savvy.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.
