如何在QTableWidget中使用Filter选项

from PyQt5.QtWidgets import QApplication, QMainWindow, QTableWidget, QTableWidgetItem, QLineEdit, QVBoxLayout, QWidget
from PyQt5.QtCore import Qt

class MainWindow(QMainWindow):
    def __init__(self):
        super().__init__()

        layout = QVBoxLayout()
        layout.addWidget(self.filter_edit)
        layout.addWidget(self.table_widget)

        widget = QWidget()
        widget.setLayout(layout)
        self.setCentralWidget(widget)

        self.init_table()

        self.filter_edit.textChanged.connect(self.filter_table)

    def init_table(self):
        self.table_widget.setColumnCount(3)
        self.table_widget.setHorizontalHeaderLabels(['Name', 'Age', 'Gender'])

        data = [
            ['Alice', '25', 'Female'],

            ['Diana', '28', 'Female'],
            ['Eva', '32', 'Female']
        ]

        self.table_widget.setRowCount(len(data))

        for row, row_data in enumerate(data):
            for col, col_data in enumerate(row_data):
                item = QTableWidgetItem(col_data)
                self.table_widget.setItem(row, col, item)

    def filter_table(self, text):
        for row in range(self.table_widget.rowCount()):
            should_show = False
            for col in range(self.table_widget.columnCount()):
                item = self.table_widget.item(row, col)
                if text.lower() in item.text().lower():

                    break

            self.table_widget.setRowHidden(row, not should_show)

if __name__ == '__main__':
    app = QApplication([])
    window = MainWindow()
    window.show()
    app.exec_()
