The easiest way is to right-click on a newly created JTable in the
Matisse (=Netbeans Swing GUI editor) -> "Table contents..." -> Columns
-> <add and remove columns as you like> and then switch to code view
and expand the folded generated code.

HTH.

I start getting into doubt if I got it right, what you are trying to achieve.

Adding a row to a table with default table model is quite simple -
just to give an example:

public static void addTableRow(DefaultTableModel model, String... columns)
{
model.addRow(columns);
}

Not sure why you are using the Vector.

For setting a particular value by giving it's row and column use
model.setValueAt.
Just an important thing (if you don't already know): Don't mix up row
index in table with row and column index in model - it is not the same
for both if the table gets sorted or columns get moved.

Seriously, just go and create your own table model:

It's rare to see anyone use a default model beyond the first 15 mins of prototyping...

Indeed - undergone same "conversion", although it took me maybe 30 mins. ;-)
