Sorting colored cell in JTable

Question

First, i'm sory for my bad english
I've made a JTable that have a column contains different colored cell each row depend on value at that cell. Like some post at many forums, I'm using DefaultTableCellRenderer with overiding getTableCellRendererComponent() and calling setBackground(Color c) from that return Component object .
At the first time data loaded into table, all is working well (each cell has their suitable color), but when I sort the table by clicking their header, the bacground color still at the fix cell (not sorted)
Any idea for this?
Thnks before.

Thanx to Axel.
Yes, right, it's working in TableSorterDemo.java
that code coloring the cell depen on its value
but my app need to be colored only at specific column, so i need the value of column
i just try to modify at your code like this:
         table.setDefaultRenderer(Integer.class, new DefaultTableCellRenderer() {
             public Component getTableCellRendererComponent (JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {
                 Component cell = super.getTableCellRendererComponent (table, value, isSelected, hasFocus, row, column);
                 cell.setBackground(Color.white);
                 if(value instanceof Integer) {             
                     if ((new Integer(5)).equals(value)) {
                         cell.setBackground(Color.yellow);
                     } else if((new Integer(3)).equals(value)) {
                         cell.setBackground(Color.green);
                     } else if((new Integer(20)).equals(value)) {
                         cell.setBackground(Color.red);
                 if(column == 0){ //not working, n it should not :D
                cell.setBackground(Color.red);
                 return cell;
but, didn't work
so i set the CellRenderer using column approach in my app, like this:
DefaultTableCellRenderer leftCellRenderer = new DefaultTableCellRenderer() {
            @Override
            public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {
                Component cell = super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);
                super.setHorizontalAlignment(SwingConstants.LEFT);
                return cell;
        DefaultTableCellRenderer centerCellRenderer = new DefaultTableCellRenderer() {
            @Override
            public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {
                Component cell = super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);
                super.setHorizontalAlignment(SwingConstants.CENTER);
                return cell;
        DefaultTableCellRenderer coloredCellRenderer = new DefaultTableCellRenderer() {
            @Override
            public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {
                Component cell = super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);
                super.setHorizontalAlignment(SwingConstants.CENTER);
                if (value.equals(" ")) {
                    cell.setBackground(Color.GREEN);
                } else {
                    cell.setBackground(Color.RED);
                return cell;
        myTable.getColumnModel().getColumn(1).setCellRenderer(leftCellRenderer);
        myTable.getColumnModel().getColumn(0).setCellRenderer(centerCellRenderer);
        myTable.getColumnModel().getColumn(2).setCellRenderer(centerCellRenderer);
        myTable.getColumnModel().getColumn(3).setCellRenderer(centerCellRenderer);
        myTable.getColumnModel().getColumn(4).setCellRenderer(coloredCellRenderer);And all works fine :-)
Thanks.
