Applying QStyledItemDelegate to a cell in QTreeView

I'm developping an application that allows to read and edit json files on pyqt5; the aplication lets the user make changes to the data, by default it lets the user edit by hand the fields, however I prefer them to select the information from the a set of options to avoid wrong editions.

To achieve this I am creating an multiple delegates, as an exaple in the code below Delegate_1 and delgate_2 that inherit from QStyledItemDelegate and rewrites the createEditor method. Searching in internet I found three methods from the class QTreeView that can be used to apply the delegates to different situations: setItemDelegateForColumn, setItemDelegateForRow and setItemDelegate, the fist two are works for full columns or rows and the third works for the whole tree, however my intention is to use the delegate_1 for cell with the index (0, 1), and the delegate_2 for the index (1, 1).

is there a method of QTreeView or a way to achieve that ?

import sys
from PySide2.QtWidgets import *
from PySide2.QtGui import *
from PySide2.QtCore import *

class Delegate_1(QStyledItemDelegate): 
    def createEditor(self, parent, option, index):
        combo = QComboBox()
        combo.addItem('BINARY')
        combo.addItem('ASCII')
        return combo

    def setModelData(self, editor, model, index):
        txt = editor.currentText()
        model.setData(index, txt)

class Delegate_2(QStyledItemDelegate):
    def createEditor(self, parent, option, index):
        combo = QComboBox()
        combo.addItem('True')
        combo.addItem('False')
        return combo

    def setModelData(self, editor, model, index):
        txt = editor.currentText()
        model.setData(index, txt)

if __name__ == '__main__':

    app = QApplication(sys.argv)

    model = QStandardItemModel(2, 2)
    
    it = QStandardItem('File_mode')
    model.setItem(0, 0, it)
    it = QStandardItem('ASCII') # apply delegate_1 to the cell
    model.setItem(0, 1, it)

    it = QStandardItem('Opened')
    model.setItem(1, 0, it)
    it = QStandardItem('True') # apply delegate_2 to the cell
    model.setItem(1, 1, it)

    t = QTreeView() # <- it's json data 
    t.setModel(model)
    t.setItemDelegateForColumn(1, Delegate_1()) # <- column 1  
    #t.setItemDelegate(Delegate()) # <- all cells
    t.show()
    sys.exit(app.exec_())

Thanks for your help

In the createEditor method, you can call the index.row() and index.column() methods, and depending on the row and column values, create the necessary editor.

def createEditor(self, parent, option, index):
    if index.row() == 0 and index.column() == 1:
        combo = QComboBox()
        combo.addItem('BINARY')
        combo.addItem('ASCII')
        return combo
    elif index.row() == 1 and index.column() == 1:
        combo = QComboBox()
        combo.addItem('True')
        combo.addItem('False')
        return combo
