    Please post code in the form of an SSCCE. Also, please use proper English, as many of our users are not native English speakers, and using "y" instead of "why" can be confusing.

    But here's a guess: the Component returned from the call to super.getTableCellRendererComponent() is in fact a JLabel. By default, JLabels are not opaque, which means their backgrounds are not painted. You can call the setOpaque() method on your c variable, but you'll have to cast it first.
