how can i Polutate table Widget with combo Box and spinBox delegates - qcombobox

Question

How can i have different delegates in different columns of a table. for instance, i want spinbox delegate in 1st column and combobox in 2nd column.
i took an example of spinbox delegate from examples directories and tried to do the changes:
main.cpp
#include "test1.h"
#include <QApplication>
#include <QHeaderView>
#include <QStandardItemModel>
#include <QTableWidget>
int main(int argc, char *argv[])
{
QApplication app(argc, argv);
QStandardItemModel model(4, 2);
QTableView tableView;
tableView.setModel(&model);
SpinBoxDelegate sdelegate;
ComboBoxDelegate comDel;
tableView.setItemDelegate(&sdelegate);
tableView.horizontalHeader()->setStretchLastSection(true);
for (int row = 0; row < 4; ++row)
{
for (int column = 0; column < 1; ++column)
{
tableView.setItemDelegate(&comDel);
QModelIndex index = model.index(0, 0, QModelIndex());
}
for (int column = 1; column < 2; ++column)
{
tableView.setItemDelegate(&sdelegate);
QModelIndex index = model.index(1, 1, QModelIndex());
}
}
tableView.setWindowTitle(QObject::tr("Spin Box & combo Box Delegate"));
tableView.show();
return app.exec();
}
