Verificar se JTable é vazia


Everton.

Question

Estou tentando inserir um JOptionPane de tabela vazia, mas estou com problemas na condição.

//Metodo
 private void VerificaTabela(){  
  
        for(int i = 0; i <tableTabela.getRowCount(); i++){  
                              
                if(tableTabela.getValueAt(i,0).toString().equals("")){  
                JOptionPane.showMessageDialog(null, "Erro...", "Não existe dependentes com esse cnpj", JOptionPane.ERROR_MESSAGE);
                }  
  
        }  
          
       }
// TableModel

  Consulta_Dependente_CRUD dao = new Consulta_Dependente_CRUD();

            List<Consulta_Dependente> lista = (List<Consulta_Dependente>) dao.listaEmpresa(cnpj);

            DefaultTableModel modelo = (DefaultTableModel) jtableTabela.getModel();
            modelo.setRowCount(0);
           
            for (Consulta_Dependente e : lista) {
                modelo.addRow(new Object[]{
                    e.getRazao(),
                    e.getCCnpj(),
                    e.getDNome(),
                    e.getDCpf(),
                    e.getDRg(),
                    e.getDTelComercial(),
                    e.getDEmail(),




                });

            VerificaTabela();


            }

            }

        
            co.Fechar_Conexao();


        } catch  (SQLException exc) {
            JOptionPane.showMessageDialog(null, "Erro: " + exc.getMessage(), "Consulta de proposta", JOptionPane.ERROR_MESSAGE);
        }
