问如何在不影响其他单元格的情况下对QTableWidget的一个单元格进行样式设计？

class BackgroundColorDelegate : public QStyledItemDelegate

            // Now you can override the background color based on some criteria,
            // in the data for example, or the Delegate could have a custom
            // property which the View sets as needed.
            if (idx.data(Qt::UserRole).toString() == "color-me-blue")
                o->backgroundBrush = QBrush(Qt::blue);
        }
