How to change the cell text color in a QTableView?

[vrltwe]

I've tried this (without success):

ui->tableView->model()->setData(ui->tableView->model()->index(5, 5, QModelIndex()), QVariant(QColor(Qt::red)), Qt::DecorationRole);

ui->tableView->model()->setData(ui->tableView->model()->index(5, 5, QModelIndex()), QVariant(QColor(Qt::red)), Qt::DecorationRole);

To copy to clipboard, switch view to plain text mode 

Thanks in advance.
