    Default jtable cell renderer

    Have a quick question regarding setting my custom cellrenderer to a jtable.

    I can set the renderer for a jtable column using the code

    Java Code:
    TableColumnModel cm = table.getColumnModel();
    TableColumn tc = cm.getColumn(0);
    tc.setCellRenderer(new myCustomRenderer());
    Now this works just fine. What i want to ask is can have more that one type of renderer in the same column. I want the cell to have different renderer based on its value (+ve/-ve).

    Also on a side note, is it possible to assign MouseListener to a specific cell in the table ?

    Any help would be much appreciated

    You have to change the single renderer so that it treats the cells differently. Likewise, you can have a MouseListener on the table that only does things when specific cells are involved.

    For handling MouseEvents on specific cells, use something like
    Java Code:
    public void mouseClicked(MouseEvent me){
         if(myList.locationToIndex(me.getPoint() == indexToPerformOn){
              //Perform action
    if you need to have extremely different actions for each index, you may want to subclass JTable and add a performIndexAction(int index) method or something like it that calls the action for the specified index, but that could become complicated.
    If the above doesn't make sense to you, ignore it, but remember it - might be useful!
    And if you just randomly taught yourself to program, well... you're just like me!
