How to Highlight row table if given a condition?

问题

I have a jtable which is consists of columns :

C No, Borrower, Market, Loan, Start, Daily, Expiry

how can i highlight the table row if the current date is 5 days away from the date inside the column 'expiry'?

    SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");     
            Calendar cal  = Calendar.getInstance();           
            String expDateString = sdf.format(cal.getTime()).toString();
            System.out.println(expDateString);
             String nana = tableSummary.getModel().getValueAt(row, 6).toString();
            System.out.println(nana);


            for(int i=0; i<=tableSummary.getRowCount()-1; i++){

                   if(nana.compareTo(expDateString)>=0){                           
                       rowrenderer.setBackground(Color.RED);

                   }
             }

Because you want to highlight every cell in the same row as a qualifying Expiry, you should override prepareRenderer(), as shown in this example and discussed in this Q&A. You can determine a matching row using the methods of Calendar. getInstance(), and you can change the color using the renderer's setBackground() method.
