如何将数据头添加到Qt中的QTableWidget？

#include <QApplication>
#include <QTableWidget>
#include <QVBoxLayout>
#include <QWidget>

int main(int argc, char *argv[]) {
  QApplication app(argc, argv);

  QWidget window;
  QVBoxLayout layout(&window);

  QTableWidget tableWidget;
  tableWidget.setColumnCount(3);
  tableWidget.setRowCount(5);

  QStringList headerLabels;
  headerLabels << "Column 1" << "Column 2" << "Column 3";

  tableWidget.setHorizontalHeaderLabels(headerLabels);

  layout.addWidget(&tableWidget);

  window.show();

  return app.exec();
}
