Problems to the popular Tableview

Question

Good morning!

When I run the code my Tableview pulls 2 blank lines. I am not able to show the inforamations in table view. Follow code below:

Controller:

package br.com.unitymanager.controller;

import br.com.unityamanager.tableview.TableCliente;
import br.com.unitymanager.dao.ClienteDao;
import br.com.unitymanager.model.Cliente;
import br.com.unitymanager.stage.Telas;
import java.io.IOException;
import java.net.URL;
import java.util.ArrayList;
import java.util.List;
import java.util.ResourceBundle;
import javafx.collections.FXCollections;
import javafx.collections.ObservableList;
import javafx.event.ActionEvent;
import javafx.fxml.FXML;
import javafx.fxml.Initializable;
import javafx.scene.control.Button;
import javafx.scene.control.TableColumn;
import javafx.scene.control.TableView;
import javafx.scene.control.cell.PropertyValueFactory;


public class FXMLTelaGerenciadorEmpresaController implements Initializable {
    
    @FXML private TableView<TableCliente> tbCliente;
    @FXML private TableColumn<TableCliente, Integer> colunaCodigoCliente;
    @FXML private TableColumn<TableCliente, String> colunaDoc;
    @FXML private TableColumn<TableCliente, String> colunaRazao;
    @FXML private TableColumn<TableCliente, String> colunaTelefone;
    @FXML private Button btnCadastrar;
    
    private final Telas chamarTelas = new Telas();
    
    private ClienteDao daoCliente = new ClienteDao();
    private List<Cliente> listCliente = daoCliente.listarClientes();
    private ObservableList<TableCliente> listPessoaTabela = FXCollections.observableArrayList();
    
    private void populandoTabela(){
        
        if(!listPessoaTabela.isEmpty()){
            listPessoaTabela.clear();
        }
        
        for(Cliente cliente : listCliente){
            TableCliente tabCli = new TableCliente(cliente);
            tabCli.mostrandoInforamcoes();
            listPessoaTabela.add(tabCli);
        }
        colunaCodigoCliente.setCellValueFactory(new PropertyValueFactory<TableCliente, Integer>("Cód.Cliente"));
        colunaDoc.setCellValueFactory(new PropertyValueFactory<TableCliente, String>("CNPJ/CPF"));
        colunaRazao.setCellValueFactory(new PropertyValueFactory<TableCliente, String>("Razão Social"));
        colunaTelefone.setCellValueFactory(new PropertyValueFactory<TableCliente, String>("Telefone"));
        tbCliente.setItems(listPessoaTabela);
     
    }
    @FXML
    void actionButtonCadastrarCliente(ActionEvent event) throws IOException {
        chamarTelas.telaCadastroCliente();
    }
    
    @Override
    public void initialize(URL url, ResourceBundle rb) {
        populandoTabela();
    }    
    
}

Tablecliente:

package br.com.unityamanager.tableview;

import br.com.unitymanager.model.Cliente;
import javafx.beans.property.SimpleIntegerProperty;
import javafx.beans.property.SimpleStringProperty;

public class TableCliente {

    private final SimpleIntegerProperty codCliente;
    private final SimpleStringProperty docCliente;
    private final SimpleStringProperty razaoSocialCliente;
    private final SimpleStringProperty telefoneCliente;
    private Cliente client;
    
    public TableCliente(Cliente cli){
        this.client = cli;
        this.codCliente = new SimpleIntegerProperty(cli.getCodigoCliente());
        this.docCliente = new SimpleStringProperty(cli.getDocCliente());
        this.razaoSocialCliente = new SimpleStringProperty(cli.getRazaoSocialCliente());
        this.telefoneCliente = new SimpleStringProperty(cli.getTelefoneCliente());
    }
    public Cliente getCliente() {
        return client;
    }
    public void mostrandoInforamcoes(){
        System.out.println(this.codCliente);
        System.out.println(this.docCliente);
        System.out.println(this.razaoSocialCliente);
        System.out.println(this.telefoneCliente);
    }
    
    public int getCodCliente() {
        return codCliente.get();
    }

    public String getDocCliente() {
        return docCliente.get();
    }

    public String getRazaoSocialCliente() {
        return razaoSocialCliente.get();
    }

    public String getTelefoneCliente() {
        return telefoneCliente.get();
    }   
}
