Iterate JTable in JTextArea

I want to iterate jTable in jTextArea

I tried this code :

int row = tableModel.getRowCount();

        for (int i = 0; i < row; i++) {
                jRcRprtTextArea.setText("___________________________________\n"
                        + "Item Name    Price   Qty.    Total\n"
                        + "_____________________________________________");
        jRcRprtTextArea.append("\n"
                + tableModel.getValueAt(i, 1)
                + "\t" + tableModel.getValueAt(i, 2)
                + "\t" + tableModel.getValueAt(i, 3)
                + "\t" + tableModel.getValueAt(i, 5)
        );
    }

But this doesn't work
Even I tried for single row in for loop but it also doesn't what I want to achieve.
I expecting jTextArea must have all text from jTable as if I'll add new row to jTable.
Previous text disappearing from jTextArea and just newly added row text adding there. Here I can see that all rows printing using println() method.
So why does not it getting in jTextArea?

Try this sample code. It should work.

Main point is that you need to call the JTextArea.setText() within a TableModelListener. I've corrected the column indices in your code. And the headers of the text area is moved out of the for loop.

import javax.swing.event.TableModelListener;

public class TableToTextArea
{
  private static DefaultTableModel tableModel;
  private static JTextArea textArea = new JTextArea();

  public static void main(String[] args)
  {
    JButton button = new JButton("Add Row");
    button.addActionListener(new ActionListener()
    {
      @Override
      public void actionPerformed(ActionEvent e)
      {
        tableModel.addRow(new String[] {"Abc", "15", "2", "30"});
      }
    });

    JFrame f = new JFrame("Table to Text Area");
    f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    f.getContentPane().setLayout(new GridLayout(3, 1));
    f.getContentPane().add(new JScrollPane(buildTable()));
    f.getContentPane().add(new JScrollPane(textArea));
    f.getContentPane().add(button);
    f.setBounds(300, 200, 500, 400);
    f.setVisible(true);
  }

  private static JTable buildTable()
  {
    tableModel = new DefaultTableModel(new String[0][0], new String[] {"Item Name", "Price", "Qty", "Total"});
    tableModel.addTableModelListener(new TableModelListener()
    {
      @Override
      public void tableChanged(TableModelEvent e)
      {
        int row = tableModel.getRowCount();

        textArea.setText("_____________________________________________\n"
            + "Item Name\tPrice\tQty.\tTotal\n"
            + "_____________________________________________");
        for (int i = 0; i < row; i++)
        {
          textArea.append("\n"
              + tableModel.getValueAt(i, 0) // Column index is changed
              + "\t" + tableModel.getValueAt(i, 1) // Column index is changed
              + "\t" + tableModel.getValueAt(i, 2) // Column index is changed
              + "\t" + tableModel.getValueAt(i, 3) // Column index is changed
          );
        }
      }
    });
    return new JTable(tableModel);
  }
}
