  product_menu.addAction(widegetMenu)

  #self.linedit_in_table.setFocusPolicy(Qt.StrongFocus)


  
  self.parent.Order_tabel.setCellWidget(row, 1, self.linedit_in_table)      
  self.linedit_in_table.setFocus(Qt.OtherFocusReason)
  product_menu.popup(self.parent.Order_tabel.mapToGlobal(QPoint(self.parent.Order_tabel.columnViewportPosition(1)+2,self.parent.Order_tabel.rowViewportPosition(row) +55)))

  self.linedit_in_table.textEdited.connect(lambda : [product_menu.setVisible(True), self.linedit_in_table.setFocus(Qt.OtherFocusReason)])

For tables and trees, the best way is to subclass a QItemDelegate and setting a QLineEdit with a Completer inside.
