Change Mousepointer and font color by entering a cell in Qtableview

Question

I tried something out with QTableview and want that the mousepointer changed to "hand" and font color changed to blue if I enter a specific cell in QTableview. Is that possible? So the cell should be use like a button without being a button.

I provide you a demo, maybe you want this.

import numpy as np

class Model(QAbstractTableModel):
    def __init__(self):
        super().__init__()
        self._data = np.random.randint(0, 255, (5, 10))
        self._color = dict()

    def rowCount(self, parent: QModelIndex = ...) -> int:
        return self._data.shape[0]

    def columnCount(self, parent: QModelIndex = ...) -> int:
        return self._data.shape[1]

    def data(self, index: QModelIndex, role: int = ...) :
        if index.isValid() and role == Qt.DisplayRole:
            return str(self._data[index.row(), index.column()])

        if index.isValid() and role == Qt.ForegroundRole:
            if f"{index.row(),index.column()}" in self._color:
                return self._color[f"{index.row(),index.column()}"]

    def setData(self, index: QModelIndex, value, role: int = ...) -> bool:
        if index.isValid() and role == Qt.ForegroundRole:
            self._color = dict()
            self._color[f"{index.row(),index.column()}"] = value
            self.dataChanged.emit(self.index(0,0), self.index(self.rowCount()-1, self.columnCount() -1))
            return True
        return super().setData(index, value, role)


class View(QTableView):
    def mouseMoveEvent(self, e: QMouseEvent) -> None:
        index = self.indexAt(e.pos())
        if index.isValid():
            self.model().setData(index, QBrush(Qt.blue), Qt.ForegroundRole)
            self.setCursor(Qt.PointingHandCursor)
        else:
            self.setCursor(Qt.ArrowCursor)
        return super().mouseMoveEvent(e)


app = QApplication([])
v = View()
v.setMouseTracking(True)
v.setModel(Model())
v.show()
app.exec()
