Alguém pode me dizer que erro tá dando na hora da construçaõ dessa Tabela. Já que existe um construtor de JTable que aceita como argumento dois Vector como:

JTable(Vector rowData, Vector columnNames)

import javax.swing.*;
import java.awt.*;
import java.sql.*;
import java.util.*;

public class Teste extends JFrame&#123;

	
	public Teste&#40;&#41;&#123;
		
		  Vector coluna_1 = new Vector&#40;&#41;;
			Vector coluna_2 = new Vector&#40;&#41;;
									
			coluna_1.addElement&#40;"carlos"&#41;;
			coluna_1.addElement&#40;"carlos"&#41;;
			coluna_1.addElement&#40;"carlos"&#41;;
			coluna_2.addElement&#40;"carlos"&#41;;
			coluna_2.addElement&#40;"carlos"&#41;;
			coluna_2.addElement&#40;"carlos"&#41;;
			
			System.out.println&#40;coluna_1&#41;;
		  System.out.println&#40;coluna_2&#41;;
						
			JTable tabela = new JTable&#40;coluna_1, coluna_2&#41;; 			
			JScrollPane jsp = new JScrollPane&#40;tabela&#41;;
			Container c = getContentPane&#40;&#41;;
			c.add&#40;jsp, BorderLayout.CENTER&#41;;
			setSize&#40;350, 120&#41;;
			show&#40;&#41;;	
	&#125;
	
	public static void main&#40;String args&#91;&#93;&#41;&#123;
	
		new Teste&#40;&#41;;
	&#125;

aí New__Radical,

ok, fiz as mudanças q vc falou, so que tá dando um problema, só tá aparecendo nas linhas da tabela “carlos” e “carlos_1”. Nas colunas não tem problema está aparecendo “senha” e “operador”;

valeu!!!

import javax.swing.*;
import java.awt.*;
import java.sql.*;
import java.util.*;


public class Teste extends JFrame&#123;

	
	public Teste&#40;&#41;&#123;
		
		  Vector coluna_1 = new Vector&#40;&#41;;
			Vector coluna_2 = new Vector&#40;&#41;;
			Vector coluna_3 = new Vector&#40;&#41;;

Cara, para as linhas, tem que ser um Vector de Vector's.
Acho que assim funfa legal! :D

...
		Vector coluna_1 = new Vector&#40;&#41;;
		Vector coluna_2 = new Vector&#40;&#41;;
		Vector linha = new Vector&#40;&#41;;

		coluna_1.addElement&#40;&quot;carlos&quot;&#41;;
		coluna_1.addElement&#40;&quot;carlos&quot;&#41;;
		coluna_1.addElement&#40;&quot;carlos&quot;&#41;;
		coluna_2.addElement&#40;&quot;carlos&quot;&#41;;
		coluna_2.addElement&#40;&quot;carlos&quot;&#41;;
		coluna_2.addElement&#40;&quot;carlos&quot;&#41;;
		linha.addElement&#40;coluna_2&#41;;

		System.out.println&#40;coluna_1&#41;;
		System.out.println&#40;coluna_2&#41;;

		JTable tabela = new JTable&#40;linha, coluna_1&#41;;

Assim, para cada linha, tem que ser um vector! :wink:

Vector coluna_1 = new Vector&#40;&#41;; 
         Vector coluna_2 = new Vector&#40;&#41;; 
         Vector coluna_3 = new Vector&#40;&#41;; 
         Vector coluna_4 = new Vector&#40;&#41;; 
                            
         coluna_1.addElement&#40;&quot;operador&quot;&#41;; 
         coluna_1.addElement&#40;&quot;senha&quot;&#41;; 
                   
         coluna_2.addElement&#40;&quot;carlos&quot;&#41;; 
         coluna_2.addElement&#40;&quot;carlos_1&quot;&#41;; 
         coluna_4.addElement&#40;&quot;carlos_2&quot;&#41;; 
         coluna_4.addElement&#40;&quot;carlos_3&quot;&#41;; 

         coluna_3.addElement&#40;coluna_2&#41;;           
         coluna_3.addElement&#40;coluna_4&#41;; 
                   
         JTable tabela = new JTable&#40;coluna_3, coluna_1&#41;;

E não, um único Vector para todas as linhas.
