我正在使用 PyQt5 開(kāi)發(fā)一個(gè) Python GUI 應(yīng)用程序，它有一個(gè)用于顯示數(shù)據(jù)的 QTableView。這是代碼：import sysfrom PyQt5 import QtWidgets, QtCorefrom PyQt5.QtCore import Qtclass DataModel(QtCore.QAbstractTableModel): def __init__(self): super().__init__() self.data = [] def data(self, index, role): if role == Qt.DisplayRole: return self.data[index.row()][index.column()] def rowCount(self, index): return len(self.data) def columnCount(self, index): return len(self.data[0])class MainWindow(UI.UserInterface): def __init__(self): super().__init__() self.model = DataModel() self.load() self.TableView.setModel(self.model) self.TableView.resizeColumnsToContents() self.TableView.horizontalHeader().setStretchLastSection(True) def load(self): try: self.model.data = [(1, '2020-01-10 00:00:00', 'KANIA', 'HENRYK', 4219)] except Exception: passif __name__ == "__main__": app = QtWidgets.QApplication(sys.argv) window = MainWindow() window.show() app.exec_()該類(lèi)UI.UserInterface位于單獨(dú)的模塊中。它具有QWidgets的界面和布局QWidgets。其中之一是QTableView。我似乎找不到一種方法來(lái)設(shè)置QTableView.我尋找了不同的解決方案（其中一些如下），但沒(méi)有一個(gè)有效：https://doc.qt.io/qt-5/sql-presenting.html（這個(gè)是C++寫(xiě)的，不太懂）

您必須實(shí)施headerData()：
class DataModel(QtCore.QAbstractTableModel):
? ? # ...
? ? def headerData(self, section, orientation, role=QtCore.Qt.DisplayRole):
? ? ? ? if orientation == QtCore.Qt.Horizontal and role == QtCore.Qt.DisplayRole:
? ? ? ? ? ? return 'Column {}'.format(section + 1)
? ? ? ? return super().headerData(section, orientation, role)
顯然，即使使用包含要顯示的標(biāo)簽的簡(jiǎn)單列表，您也可以設(shè)置自己的標(biāo)簽。
請(qǐng)注意，為子類(lèi)命名新屬性時(shí)應(yīng)非常小心，因?yàn)樗鼈兛赡芤呀?jīng)存在。
最重要的是，您不應(yīng)該覆蓋self.data.

這是一個(gè)使用 QtableView 和一組 headerdata 的示例，您將能夠修改 tableview 中的數(shù)據(jù)
def exemple_table(self):
? ? ? ? database = QSqlDatabase("QPSQL")
? ? ? ? database.setHostName("localhost")
? ? ? ? database.setDatabaseName("database")
? ? ? ? database.setUserName("postgres")
? ? ? ? database.setPassword("password")
? ? ? ? database.open()
? ? ? ??
? ? ? ? model_ft = QSqlTableModel(db=database)
? ? ? ? model_ft.setTable('table')
? ? ? ??
? ? ? ? model_ft.setHeaderData(0, Qt.Horizontal,"id")
? ? ? ? model_ft.setHeaderData(1, Qt.Horizontal,"exemple01")
? ? ? ? model_ft.setHeaderData(2, Qt.Horizontal,"exemple02")
? ? ? ? model_ft.setHeaderData(3, Qt.Horizontal,"exemple03")
? ? ? ? model_ft.setHeaderData(4, Qt.Horizontal,"exemple04")
? ? ? ? model_ft.setHeaderData(5, Qt.Horizontal,"exemple05")
? ? ? ? model_ft.setHeaderData(6, Qt.Horizontal,"exemple06")
? ? ? ? model_ft.setHeaderData(7, Qt.Horizontal,"exemple07")
? ? ? ??
? ? ? ? model_ft.removeColumns(8,1)
? ? ? ? date = str(datetime.date.today())
? ? ? ??
? ? ? ? self.tableView.setModel(model_ft)
? ? ? ? self.tableView.horizontalHeader().setSectionResizeMode(QHeaderView.Stretch)
? ? ? ??
? ? ? ? model_ft.setSort(0, Qt.DescendingOrder)
? ? ? ? model_ft.select()
? ? ? ? filter_ft = "date_d ='%s' " % (date_1)
? ? ? ? model_ft.setFilter(filter_ft)
