background of multiline cell in JTable

Question

I make a table with multiline cell, it worked fine, but I want to change the color of a single row after making specific colomns muliline cell, not the color of the whole colomn. How can i do that?

here is an image after making colomn 2 multiline cell, but the whole colomn become white

this is what i did :

jTable1.getColumnModel().getColumn(1).setCellRenderer( new TextAreaRenderer2()); 

String test = "sunday \n monday ";

jTable1.getModel().setValueAt(test, 0, 3);
jTable1.getModel().setValueAt(test, 0, 1);
jTable1.getModel().setValueAt(test, 0, 2);

and this is TextAreaRenderer2 class :

public class TextAreaRenderer2 extends JTextArea
     implements TableCellRenderer {

     public TextAreaRenderer2() {

         Font font = new Font("Aparajita", Font.BOLD + Font.ITALIC, 16);

         setLineWrap(true);
         setWrapStyleWord(true);
         setBackground(Color.yellow);
         setBorder(BorderFactory.createEmptyBorder());
         setFont(font);

     } 

     @Override
     public Component getTableCellRendererComponent(JTable jTable,
          Object obj, boolean isSelected, boolean hasFocus, int row,
          int column) {

         setText((String)obj);
         setBackground(Color.WHITE);


         return this;
     }
 }

Answer 1

In your TableAreaRenderer2 class, in the getTableCellRendererComponent method you should set the background color based on the row. Something like this:

if (row % 6 < 3) {
  setBackground(Color.LIGHT_GRAY);
} else {
  setBackground(Color.WHITE);
}

The above code will make 3 rows light gray the next 3 white and repeat the same pattern.
