Changing JTable column names

I have a JTable where the user can right click on the table header to change what data is displayed. When the user selects different data to display, I would like to change the column name to reflect this. What is the best way to do this?
TIA

Hi,
Add the following CSS Code to the custom skin css file that is to be created as per the suggestions above.
*af|column::column-header-cell{*
color:Blue;
font-weight:bold;
This would ensure that all the table column headers are blue in color and bolder font style through-out the application.
By the way, what version of JDeveloper are you using?

Hi ,
If you want to change the column name, you can put your code following:
<htmlb:tableViewColumn columnName    = " "
           *title        = " put the cloumn name here"*
           </htmlb:tableViewColumn>
Please try.
Any doubt let me know.

Column prompts can be modified through the OAF Personalization screens. This will ensure you are declaratively setting the values.

Changing the column names displayed via an ODBC driver

Hi we are just starting to used Crystal Reports to improve the reporting capabaility of a legacy application, we can access the data fine using an ODBC driver. What we want to do is change the column names that are displayed within Crystal Reports so they are more user friendly and not in techno speak,, so that the users can create their own reports. Do we need to used Business Objects to setup a Universe to do this, is their a simple cheaper method sorry if this post is in the wrong section

Can you set up "views" in your database?Â That would probably be the easiest way to do this.

Change a column name

What is the correct syntax to change a column name. say
ID VARCHAR2(10)
to
ID_NO VARCHAR2(10)

You can alternatively do this:
Connect as sys user and run the following script:
SELECT obj# from obj$
where name = 'Your_Table_Name';
SELECT col# from col$
where obj# = obj# from previous query
and name = 'your_column_name which you want to rename';
update col$ set name = 'your_new_name'
where obj# = obj# from the first query
and col# = col# from previous query;
Alter system flush shared_pool;
connect as your user and you will see the change there.
Hope this helps

How to change JTable column header text

How do you set the text in the JTable column headers? I know you can create a JTable specifying the text in an array:
<li>JTable(Object[][] rowData, Object[] columnNames)
But if you create the JTable specifying a TableModel,
<li>JTable(TableModel dm)
the header text defaults to "A", "B", "C", etc. I cannot figure out how to access the text in the header names so it can be changed to something useful. I know how to get the JTableHeader for the table, but it does not seem to have methods for actually setting header values.

I'm sure that model allows you to specify header values so you don't have to do so manually. I would be very surprised if it didn't override the default getColumnName() method to provide a reasonable names.She wasn't writing the class, but [url http://forums.oracle.com/forums/thread.jspa?messageID=9200751#9200751]outlining a design for me to implement. And, based on a previous comment I had made, I think she assumed I wanted the new design to look as much like the old as possible. There were no headers in the original design, which wasn't even a table.
Anyway, this works:
    final static String statisticsColumnNames[] = {
     "Type", "Count",
     "Red QE", "Green QE", "Blue QE", "Average QE",
     "Distance"
     qErrors = new QEBeanTableModel();
     JTable errorTable = new JTable(qErrors);
     TableColumnModel tcm = errorTable.getColumnModel();
     for (int col = 0; col < statisticsColumnNames.length; col++)
         tcm.getColumn(col).setHeaderValue(statisticsColumnNames[col]);
It looks like setHeaderValue() on the TableColumn is what I was looking for.Again, only used if you are dynamically changing the values at run time or you don't like the defaults provided by the Bean-aware model.I coded the above before I read your last post. The QEBeanTableModel is extremely specific to my program. I.e. I cannot imagine it being used anywhere else. Would it still be better to implement a getColumnName() within the table model? Looking at your [url http://www.camick.com/java/source/RowTableModel.java]RowTableModel.java source, I can see that it would not be difficult to do so.
Just decided to add the getColumnName() method. This whole sub-project is based on implementing a clean modern design (and learning about Java Beans). You've clearly stated twice that the method I have implemented is for dynamic header values only, which has already answered what I asked last paragraph.

How can I change a column name in table (JDeveloper 10.1.3.3)?

I'd like to change a table column name, for example instead of "FirstName" I'd like "Name".
Here is the preview: http://img208.imagevenue.com/img.php?image=86575_firstname_122_578lo.JPG
Thank You in advance!

Now I have following problem: When I change "Label text" to column which has "Combo box" (Department insted of DepartmentId) I do not have my combo box anymore, just DepartmentId (Number). I have created binding... (DepartmentId -> Department Name) Why is this happening?

BTW I use ADFBC Swing

JTable column names with custom model

I'm having problems with column names in a JTable which uses a custom model. For some reason, the colums are being shown as A, B, C etc. The data, however, displays fine.
This is the code which constructs the table.
MyTableModel tableModel = new MyTableModel(myArrayList);
myTable = new JTable(tableModel);
myTable.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
myTable.setFillsViewportHeight(true);This is the class, MyTableModel
class MyTableModel extends AbstractTableModel {
        private ArrayList<Account> data;
        private String[] colNames = {"", "Name","Type","Group","Created","Modified"};
        public MyTableModel(ArrayList<Account> data) {
            this.data = data;
        public int getRowCount() {
            return data.size();
        public int getColumnCount() {
            return 6;
        public Object getValueAt(int row, int col) {
            Account account = (Account)data.get(row);
            switch(col) {
                case 0:
                    return account.getIcon();
                case 1:
                    return account.getName();
                case 2:
                    return account.getType();
                case 3:
                    return account.getGroup();
                case 4:
                    return account.getDateCreated();
                case 5:
                    return account.getDateModified();
                default:
                    return "";
        public String getColumName(int index) {
         System.out.println("N:"+colNames[index]);
            return colNames[index];
    }When the table is displayed, nothing's displayed to the console, but I'd have thought getColumnName would print the current column name. Am I missing something obvious?

Oh great. I'll go back under my rock.
Thanks =)

JTable, column names not appearing!

I am using the following code:
Vector columnNames = new Vector();
        Vector data = new Vector();
        try
            // Connect to the Database
            Common.Data.DataAccesser da = new Common.Data.DataAccesser();
            Connection connection = da.getConnection();
            // Read data from a table
            String sql = "Select * from schedule1";
            Statement stmt = connection.createStatement();
            ResultSet rs = stmt.executeQuery( sql );
            ResultSetMetaData md = rs.getMetaData();
            int columns = md.getColumnCount();
            // Get column names
            for (int i = 1; i <= columns; i++)
                columnNames.addElement( md.getColumnName(i) );
            // Get row data
            while (rs.next())
                Vector row = new Vector(columns);
                for (int i = 1; i <= columns; i++)
                    row.addElement( rs.getObject(i) );
                data.addElement( row );
            rs.close();
            stmt.close();
        catch(Exception e)
            System.out.println( e );
        // Create table with database data
        JTable table = new JTable(data, columnNames);
        jPanel2.setLayout(new java.awt.BorderLayout());
        jPanel2.add(table, BorderLayout.CENTER);I know its a bit messy, wat im tryin to do is add the table to the panel. the rows are showing perfectly but the column names do not show! Can anyone help?

1) Please ask Swing questions in the Swing forum.
2) Don't forget to specifically make the table header display. You do this by adding the table header to the jpanel in the borderlayout NORTH position, and you get the table header by calling getTableHeader. Have a look here for instance:
http://forum.java.sun.com/thread.jspa?threadID=5235339&tstart=0

JTable Column Names Not Displaying

Hi there
I create a JTable by passing the JTable constructor my custom TableModel which extends AbstractTableModel.
For column names I have a String[] containing the column names in my custom TavleModel and have coded the TableModel methods accordingly.
For some reason when I run the code the table is displayed, but the column names are not!?!
Any advance is appreciated!

Sorted!
After looking at sample code in the JTable tutorial, it seems the table likes/needs to be added to a JScrollPane, as once I did this the column headings started appearing.
e.g. JScrollPane scrollPane = new JScrollPane(table);
