Why do you say it is hard to apply on JTable? Have you checked [this tutorial](http://docs.oracle.com/javase/tutorial/uiswing/components/table.html#renderer)? — assylias, Mar 30 '12 at 13:08
JXTable (from the SwingX project) has support for Highlighters, and contains an alternate row highlighter by default, making this requirement almost a one-liner — Robin, Mar 30 '12 at 14:22
but can we apply it for each row as per db value thanks in advance — Pavan Gomladu, Mar 31 '12 at 06:27

This isn't hard at all with a JTable! In fact, it's incredibly easy!

See my answer here: Highlight a cell in JTable via custom table model

Reproduced for ease:

...Subclass JTable and override JTable.preparedRenderer(TableCellRenderer renderer, int row, int column). If the row and column numbers are the same, you can change the background color of the Component returned as the display (usually a JLabel);

Here's an example that highlights the row the mouse is over:

@Override
public Component prepareRenderer(final TableCellRenderer renderer, final int row, final int column) {
    final Component c = super.prepareRenderer(renderer, row, column);
    if (row == this.itsRow) {
        c.setBackground(Color.RED);
    }
    return c;
}

where this.itsRow is an int field updated by a MouseMotionListener:

this.addMouseMotionListener(new MouseMotionListener() {
        public void mouseMoved(MouseEvent e) {
            SubclassedJTable.this.itsRow = SubclassedJTable.this.rowAtPoint(e.getPoint());
            SubclassedJTable.this.repaint();
        }
        public void mouseDragged(MouseEvent e) {/***/}
    });

sir it is necessary to have row and column numbers are the same, to color each row as per db value rply...thanks — Pavan Gomladu, Mar 31 '12 at 06:20
