TABLE DON�T UPDATE

Question

Hi guys, I am in a limite of nervous attach!!!!! Please help me....
The problem is: I create a interface that change the table columns, based on a Combobox selecting another table. Just for visualize the table from my DB.
This code don�t update my table
fields = swttSection.getFields();                       //get the swtt section fields                                       
tagTableModel = new TagTableModel();        //create a new table model
/* For each field */
for(int j = 0; j < fields.size(); j++)
    swttField = (SwttField)fields.elementAt(j);                        //get the field                      
    tagTableModel.addColumn(swttField.getName());        //insert the new column
}//End for
createTagTable();                                       //update the table....And this update. But this don't is wich I want. Because it mantain the old columns!!! (The JTable become a BIG column).
fields = swttSection.getFields();                       //get the swtt section fields                                       
/* For each field */
for(int j = 0; j < fields.size(); j++)
    swttField = (SwttField)fields.elementAt(j);                        //get the field                      
    tagTableModel.addColumn(swttField.getName());        //insert the new column
}//End for
createTagTable();                                       //update the table

Hi, I am here again. I think that I don't explaint the problem clearly....
I have a DataBase with 5 tables, each table has your own fields, and I waana create a JTable (GUI) for the user edit the result and then, write, read, udpate, delete, etc.....
I create a DefaulttableModel...
When my program start.. In the constructor I instianciate de DefaultTableModel
DefaultTableModel model = new DefaultTableModel();Then I create a JcomboBox where the user can choose another tables. When the user do this action, I would like to change the table columns (because each table has their own columns, and this fields are different).
The I code...
JComboBox table = new JcomboBox();
table.addActionListener(this);
public void actionPerformed(ActionEvent e){
   if(e.getSource() == table)
      model = new DefaultTableModel();                //I do this to "zero" the table, for create another one
     for(int col = 0; col < sizeTable; col++)
         model.addColumn(header[col]);
      getContentPane().add(new JScrollPane(new JTable(model)));
   }//end if
}//End actionPerformed()The problem is: The JTable don't "zero" and show the new structure, it always mantain the first structure.
Just for debug I get out the new DefaulTableModel and it works adding the tables to the end.. But it is not correct because I just attach new columns form table CLIENTE on the table PRODUCT for example. please help.
Thanks. Giscard
