JCombo box inside a JTable Cell?

[ben riches]

Hello All,
Is there a way where I can get a JCombo Bok in each cell of my JTable ?
my JTable Currently looks like this:

int j=1;
      String[][] data = new String[j][2];
      for (int k=0; k<j; k++){
         String[] row = {"",""};
         data[k] = row;
      }
String[] columnNames = {"Table Name","Column Name"};
ivjScrollPaneTable = new javax.swing.JTable(data, columnNames);

ivjScrollPaneTable.putClientProperty("terminateEditOnFocusLost", Boolean.TRUE);
JTableHeader anHeader = ivjScrollPaneTable.getTableHeader();
ivjScrollPaneTable.setDefaultRenderer( Object.class, new MyTableCellRenderer() );
//ivjScrollPaneTable.getTableHeader().setReorderingAllowed(false);
ivjScrollPaneTable.getTableHeader().setForeground(java.awt.Color.blue);
ivjScrollPaneTable.getTableHeader().setFont( new Font( "Arial", Font.BOLD, 12 ) );
ivjScrollPaneTable.setSelectionForeground(java.awt.Color.black);
ivjScrollPaneTable.setForeground(java.awt.Color.black);
ivjScrollPaneTable.setGridColor(java.awt.Color.black);
ivjScrollPaneTable.setSelectionBackground(java.awt.Color.white);
ivjScrollPaneTable.setToolTipText(
    "Please enter the Table and coulmn names that you want your" +
    " data to be inserted to. Please refer to the help page for help.");
ivjScrollPaneTable.setName("ScrollPaneTable");
ivjScrollPaneTable.setAutoResizeMode(javax.swing.JTable.AUTO_RESIZE_ALL_COLUMNS);
ivjScrollPaneTable.setBounds(0, 0, 450, 400);
JScrollPane scrollPane = new JScrollPane(ivjScrollPaneTable);
ivjScrollPaneTable.setPreferredScrollableViewportSize(new Dimension(500, 70)); 

Thanks
Ben

I just thought I would let you know that I have done it like so.
But with doing it like this I cannot choose between each item that I put in the ComboBox it is all ways set to "hello". How can I make it so that I can choose between each item?
Thanks

comp.addItem("hello");
comp.addItem("ben");
return comp;
}
            
            
}

There's an example of using a JComboBox as a TableCellEditor in the Swing Tutorial.

You are seeing "hello" every time because every time the TableCellRenderer you have created is called, you return a brand new combo box. You should use TableCellEditor instead, and you should extend JComboBox, or have a single JComboBox instance in your class that you return the same reference to each time. You would set the current value by using the "value" parameter being sent to the getTableCellEditor() method.
