Как удалить определенные границы строк в виджете таблицы, используя pyqt4

Question

Здесь у меня есть пример кода, в котором мне нужно удалить границы отдельных строк в таблице widget. Я пробовал много способов, но я не мог найти какой-либо метод. Может ли кто-нибудь, пожалуйста, скажите мне, как я могу удалитьвиджет границы таблицы. Я использовал gridlayout (False), но этот метод используется для удаления всей границы таблицы. Пожалуйста, помогите мне.*

здесь я хочу показать границы только для элемента, а не для элементов описания ниже

Структура ваших данных такая же, как у дерева, поэтому вы должны использовать QTreeView или QTreeWidget, а затем вы можете установить границу с помощью делегата:

from PyQt4 import QtCore, QtGui

class InventoryDelegate(QtGui.QStyledItemDelegate):
    def paint(self, painter, option, index):
        super(InventoryDelegate, self).paint(painter, option, index)
        if not index.parent().isValid():
            painter.save()
            painter.setPen(QtGui.QPen(QtGui.QColor("green")))
            r = QtCore.QRect(option.rect)
            r.adjust(0, 1, 0, -1)
            painter.drawLine(r.topLeft(), r.topRight())
            painter.drawLine(r.bottomLeft(), r.bottomRight())
            painter.restore()

    def sizeHint(self, option, index):
        s = super(InventoryDelegate, self).sizeHint(option, index)
        s.setHeight(55)
        return s

class Inventory_Items(QtGui.QMainWindow):
    def __init__(self, parent=None):
        super(Inventory_Items, self).__init__(parent)
        self.inventory_dict = {
            "Shirt": {
                "Men Solid Formal Blue shirt": ["10.10.1(Red)", "10.10.2(blue)"],
