Disable JTable draggable? // reimporting into a JTable?

Question

How do I disable the ability to drag and drop the colons of a JTable?
I am making a database where I am importing from a file (to view, but not edit it). How can I reimport the file after I have imported it into the JTable?
This is my code at the moment.
    public void reload()
        ArrayList<String> ve = new ArrayList<String>(9); // imports the file into an ArrayList of lines
        try
            BufferedReader reader = new BufferedReader(new FileReader(source));
            String line = null;
            while ((line = reader.readLine()) != null)
                ve.add(line);
            reader.close();
        catch (IOException e)
            System.out.println("Error reading file.");
        ve.trimToSize();
        String [][] data = new String[ve.size()/9][];
        for(int i = 0; i < data.length; i++)
            data[i] = new String[9];
            String name = ve.get(9*i);
            data[0] = name;
String mobile = ve.get(9*i+1);
data[i][1] = mobile;
String dest = ve.get(9*i+2);
data[i][2] = dest;
String tranOut = ve.get(9*i+3);
data[i][3] = tranOut;
String tranIn = ve.get(9*i+4);
data[i][4] = tranIn;
String adult = ve.get(9*i+5);
data[i][5] = adult;
String number = ve.get(9*i+6);
data[i][6] = number;
String dep = ve.get(9*i+7);
data[i][7] = dep;
String arr = ve.get(9*i+8);
data[i][8] = arr;
sort(data); // run quickSort
table = new JTable(data, columnNames);
scrollPane = new JScrollPane(table);
}It works the first time it is run, but not when I try to call it later (from the menus).                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               

Answer 1

In future, Swing questions should be asked in the [Swing Forum.|http://forums.sun.com/forum.jspa?forumID=57]
The header row of a JTable is really an instance of JTableHeader . Take a look at the API and see if there are any methods that would be of use. (Hint: there are!)
