I thought I'll get some help from this forum.

I have a comboBox in a Jtable.
Now I need to update(add few more items in it) that combobox based on the other cell's value.
How can I do that?

This is what i tried... but didn't work

static{
		ComponentCreator.linguisticList = ComponentCreator.linguisticList == null ? new ArrayList<String>() : ComponentCreator.linguisticList;
		
	}
	
	public CustomInputTable(Object[][]rowData, Object[]columnNames, Class[]columnClasses, InputparameterPanel parentPanel ) {
 
		super(new CustomTableModel(rowData, columnNames, columnClasses));
		
		try{
			super.addMouseListener(this);
			
			this.parentPanel = parentPanel;
			
			setDoubleBuffered(true);
			setDragEnabled(false);
			getTableHeader().setReorderingAllowed(false);
 
			int fontSize = this.getFont().getSize();
			this.setRowHeight(fontSize+10);
			
			// select only one row at a time
			this.getSelectionModel().setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
			
			// set up "Scale Type" column
			setUpScaleTypeColumn( getColumnModel().getColumn(2), items);
			
			// set up "Ling val" column
			setUpLinguisticValColumn( getColumnModel().getColumn(3), ComponentCreator.linguisticList.toArray());
			
			initColumnSizes(this);
		}
		catch (Exception e) {
			e.printStackTrace();
		}
		
	}
	
	private void setUpScaleTypeColumn(TableColumn column, String[] items) {
		
		//Set up the editor for the cells.
		JComboBox comboBox = new JComboBox(items);		
		//column.setCellEditor(new DefaultCellEditor(comboBox));
	
		column.setCellEditor(new ScaleTypeComboBoxEditor(comboBox, this));
		
	}
 
	private void setUpLinguisticValColumn(TableColumn column, Object[] items){
 
		//Set up the editor for the cells.
		JComboBox comboBox = new JComboBox(items);		
		//column.setCellEditor(new DefaultCellEditor(comboBox));
	
		column.setCellEditor(new LingComboBoxEditor(comboBox, this));
		
	}

I've "ScaleTypeComboBoxEditor" and "LingComboBoxEditor" for two different combobox...
In ScaleTypeComboBoxEditor I've added following code to update ComponentCreator.linguisticList

@Override
	public void actionPerformed(ActionEvent ae) {
		try {
 
			System.out.print("Command: " + ae.getActionCommand());
 
			System.out.println(", Selected: "
					+ scaleTypeCombo.getSelectedItem());
 
			if (scaleTypeCombo.getSelectedItem() == null) {
				return;
			} else if (ae.getSource().equals(scaleTypeCombo)) {
 
				String scaleType = (String) ((JComboBox) ae.getSource())
						.getSelectedItem();
 
				if (scaleType.equals(ComponentCreator.LING_SCALE)) { // Linguistic
																		// Scale
 
					if (ComponentCreator.hasFuzzyLingScaleDefined) {
 
 
						this.customInputTable.invalidate();
						this.customInputTable.validate();
						this.customInputTable.getParentPanel().repaint();
						this.parentFrame.repaint();
 
					} else { // linguistic scale hasn't defined yet...
 
						// show linguistic scale dialog to create scale
						new FuzzyScaleDialog(this.parentFrame, true);
 
						// populate lingCombo
						for (int i = 0; i < linguisticScale
								.getFuzzyCatagories().size(); i++) {
							// System.out.println(linguisticScale.getFuzzyCatagories().get(i));
							// this.lingCombo.addItem(linguisticScale.getFuzzyCatagories().get(i));
							ComponentCreator.linguisticList.add(linguisticScale
									.getFuzzyCatagories().get(i));
						}
 
 
						this.customInputTable.invalidate();
						this.customInputTable.validate();
						this.customInputTable.getParentPanel().repaint();
						this.parentFrame.repaint();
					}
				}
			}
 
		} catch (Exception e) {
			System.out.println(e.getMessage());
		}
 
	}

I started to work on this, but soon lost patience. Your post is complex and needs to be more clear. First, isolate the problem by creating a SSCCE. That will also help people like us trying to help u.
