如何告诉Qt始终在QTableView中显示编辑器？

#include <QTableView>
#include <QAbstractItemModel>

QTableView *table_view = new QTableView(this);
QAbstractItemModel *model = new QStandardItemModel(this);
table_view->setModel(model);

table_view->setEditTriggers(QAbstractItemView::AllEditTriggers);

#include "mainwindow.h"
#include "ui_mainwindow.h"

#include <QTableView>
#include <QStandardItemModel>

MainWindow::MainWindow(QWidget *parent)
    : QMainWindow(parent),
      ui(new Ui::MainWindow)
{
    ui->setupUi(this);

    QTableView *table_view = new QTableView(this);
    QStandardItemModel *model = new QStandardItemModel(this);
    table_view->setModel(model);

    table_view->setEditTriggers(QAbstractItemView::AllEditTriggers);

    this->setCentralWidget(table_view);
}

MainWindow::~MainWindow()
{
    delete ui;
}
