I'm not sure if this is the right way, but I used a class derived from
AbstractTableModel to store the column names i.e
AbstractTableModel.setColumnName

This class was then used in the constructor of JTable ie new
JTable(TableModel)

My implementation of setColumnName also fired fireTableRowsUpdated(-1,column)
as well.

To get the columns to appear I had then had to remove and add all the columns
again, otherwise the new column titles wouldn't appear

dataTable is of type JTable, dataModel is the class derived from
AbstractTableModel

     TableColumnModel cm = dataTable.getColumnModel();
     while (cm.getColumnCount() > 0)
        cm.removeColumn(cm.getColumn(0));

     for(int col=0;col<dataModel.getColumnCount();col++)
     {
        dataTable.addColumn(new TableColumn(col));
     }

To actually add to the column I used AbstractTableModel.setValueAt and inside
the implementation used fireTableCellUpdated

Hope this help.

cheers,
John
