Event in jButton

Hi

I have connected a table to a database in jFrame through coding. Not the drag and drop jtable from the component panel. My problem is how will i interact with that table through the normal drag and drop jbutton? This is my code:

package crc;
import java.awt.*;
import java.io.*;
import java.sql.*;
import java.util.*;
import javax.swing.*;
import javax.swing.table.*;

import java.net.*;
import java.io.*;
import java.sql.*;

public class riz extends javax.swing.JFrame {
private Statement st;
private Connection con;
Vector columnNames = new Vector();
Vector data = new Vector();
 
    /** Creates new form riz */
    public riz() {
        initComponents();
        this.setSize(840,600);
        
        try {
            //  Connect to the Database
            
            
//            String url = "jdbc :-o	 dbc :mrgreen: ataSourceNameHere";  // if using ODBC Data Source name
            String dsn = "crc";
            
            //load driver
            Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
            
            //make connection
            con = DriverManager.getConnection("jdbc :-o	 dbc:" + dsn);
            
            //create statement
            st = con.createStatement();
            
            //  Read data from a table
            
            String sql = "Select * from Staff";
            Statement stmt = con.createStatement();
            ResultSet rs = stmt.executeQuery( sql );
            ResultSetMetaData md = rs.getMetaData();
            int columns = md.getColumnCount();
            
            //  Get column names
            
            for (int i = 1; i <= columns; i++) {
                columnNames.addElement( md.getColumnName(i) );
            }
            
            //  Get row data
            
            while (rs.next()) {
                Vector row = new Vector(columns);
                
                for (int i = 1; i <= columns; i++) {
                    row.addElement( rs.getObject(i) );
                }
                
                data.addElement( row );
            }
            
            rs.close();
            stmt.close();
        } catch(Exception e) {
            System.out.println( e );
        }
        
        //  Create table with database data
        
        JTable table = new javax.swing.JTable(data, columnNames);
        JScrollPane scrollPane = new JScrollPane( table );
        getContentPane().add( scrollPane );
        scrollPane.setBounds(0, 0, 590, 130);
 
    }
 
    public static void main(String args[]) {
        java.awt.EventQueue.invokeLater(new Runnable() {
            public void run() {
                new riz().setVisible(true);
            }
        });
    }

When i add a new button the generated code looks like this :

But when i type something like for example

jTextArea1.setText(tmodel.getRowCount);

Nothing happens. Its like the table is not there. Any help with this will be greatly appreciated.

Correction: Gave the wrong table name.

jTextArea1.setText(table.getRowCount);

still nothing happens. I dont get the row count.
