Hi,

Ive created a JTable that has one column that is full of JCombobox
objects.

The weird thing is that when I select one value in.. say row 3.., that
value is used not only in row 3, but also row 4,5, and 6 and all the
way to the bottom-1 of the table.

I created a custom celleditor and cellrenderer, code I included below
for your perusal...

--------main app code-------------
String[] values = new String[]{"  ", "Heading", "Body"};

table.getColumnModel().getColumn(table.convertColumnIndexToView(iFORMAT)).setCellEditor(new
ComboBoxEditor(values));

table.getColumnModel().getColumn(table.convertColumnIndexToView(iFORMAT)).setCellRenderer(new
ComboBoxRenderer(values));

------------combobox editor---------------
public class ComboBoxEditor extends DefaultCellEditor {
   public ComboBoxEditor(String[] items) {
       super(new JComboBox(items));
   }
}

--------------Combobox renderer----------
ublic class ComboBoxRenderer extends JComboBox implements
TableCellRenderer {
   public ComboBoxRenderer(String[] items) {
       super(items);
   }

   public Component getTableCellRendererComponent(JTable table, Object
value,
           boolean isSelected, boolean hasFocus, int row, int column)
{
       if (isSelected) {
           setForeground(table.getSelectionForeground());
           super.setBackground(table.getSelectionBackground());
       } else {
           setForeground(table.getForeground());
           setBackground(table.getBackground());
       }

       // Select the current value
       setSelectedItem(value);
       return this;
   }
}
