public Component getTableCellRendererComponent(JTable table, Object value,
        boolean isSelected, boolean hasFocus, int row, int column) {
    Component c = super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);
    if(!isSelected){
        if(row %2 ==0 && row != 1){
            c.setBackground(new Color(255,255,150));
        }   else{
            c.setBackground(Color.WHITE);
        }
    }else{
        c.setBackground(new Color(255,230,255));
    }
    c.setBorder(BorderFactory.createEmptyBorder(0,0,0,0));
    return c;
}

}

I don't know how your code compiles since only Swing components can have a Border and the Component class doesn't have a setBorder() method.

When I override the default renderer I use something like:

Class CustomRenderer extends DefaultTableCellRenderer
{
    public Component getTableCellRendererComponent(
        JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column)
    {
        super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);
        this.setBorder (BorderFactory.createBevelBorder (EtchedBorder.RAISED));
        return this;
    }
}

The lines drawn between cells are not part of the cells themselves. They are drawn by the table. You can turn them off for the entire table with:

table.setShowHorizontalLines(false);
table.setShowVerticalLines(false);

Or, you can change the color with

table.setGridColor(...)
