如何使用QItemDelegate更改QTableView文本颜色？

class ColorDelegate(QtWidgets.QItemDelegate):
    def __init__(self, parent=None):
        super(ColorDelegate, self).__init__(parent)

def createEditor(self, parent, option, index):
    editor = QtWidgets.QLineEdit(parent)
    editor.setStyleSheet("color: red;")  # 设置文本颜色为红色
    return editor

def setEditorData(self, editor, index):
    value = index.model().data(index, QtCore.Qt.DisplayRole)
    editor.setText(str(value))

def setModelData(self, editor, model, index):
    value = editor.text()
    model.setData(index, value, QtCore.Qt.EditRole)

def paint(self, painter, option, index):
    value = index.model().data(index, QtCore.Qt.DisplayRole)
    if value == "特定值":
        painter.setPen(QtGui.QColor("red"))  # 设置文本颜色为红色
    else:
        painter.setPen(QtGui.QColor("black"))  # 设置文本颜色为黑色
    painter.drawText(option.rect, QtCore.Qt.AlignLeft, str(value))

tableView.setItemDelegateForColumn(columnIndex, ColorDelegate())
