在netbeans中着色jtable行

Question

I'm new to java. What i am trying to do is to create a table that shows a list of objects. What i want is to give color for specific rows in the JTable based upon the value of the member of an object. I saw a lot of option like using "TableCellRender" and all.I have tried them too. But the problem is that am using the Netbeans IDE so that i am not creating the table by code. Can some one please help me to change row color where the table is defined by the NetBeans??

Thanks in advance.

You can use DefaultTableCellRenderer to color alternate row from JTable .

table.setDefaultRenderer(Object.class, new TableCellRenderer(){
    private DefaultTableCellRenderer DEFAULT_RENDERER =  new DefaultTableCellRenderer();

            @Override
            public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {
                Component c = DEFAULT_RENDERER.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);
                if(isSelected){
                    c.setBackground(Color.YELLOW);
                }else{
                if (row%2 == 0){
                    c.setBackground(Color.WHITE);

                }
                else {
                    c.setBackground(Color.LIGHT_GRAY);
                }     }

       //Add below code here
                return c;
            }

        });

If you want to color your row using the value of a particular row then you can use something like this. Add these line to above

if(table.getColumnModel().getColumn(column).getIdentifier().equals("Status")){//Here `Status` is column name
    if(value.toString().equals("OK")){//Here `OK` is the value of row

        c.setBackground(Color.GREEN);
    }   
}
