enum Qt::ItemDataRole

#include <QtGui/QApplication>
#include <QtGui/QStandardItemModel>
#include <QtGui/QTableView>

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

	QStandardItemModel model;
	model.setRowCount(5);
	model.setColumnCount(5);
	model.setHeaderData(0, Qt::Horizontal, "Does this helps?");
	model.setHeaderData(0, Qt::Horizontal, Qt::red, Qt::BackgroundRole);

	QTableView view;
	view.setModel(&model);
	view.show();

	return app.exec();
}
