I have an empty JTable I'm adding columns to and then rawData to.
I'm using the following code:

JTable table = new JTable();
table.addColumn(aColumn);
table.addColumn(bColumn);
// the columns are already defined, and if I run the project at this point,
// a table with 2 columns appears with no data.
// next, I try to add row data using the following code:
DefaultTableModel model = (DefaultTableModel)table.getModel();

Vector data = new Vector();
data.add(new Double(1.0));
data.add(new Double(2.0));
model.addRow(data);

// OR

Object[] rowData = {new Double(1.0), new Double(2.0)};
model.addRow(rowData);

// both attempts throw a series of exceptions..  after adding the
// rows, the table show the correct rowCount()... any suggestions?
