它按字母数字排序（因此，按照字符串，“ 1”，“ 10”，“ 11”，“ 12”，“ 2”，“ 20”，“ 21”，“ 22”，“ 3”，“
4’等是正确的排序顺序。对于QTableWidgetItem，如果您使用setData（Qt.EditRole，value）方法，则该排序顺序将起作用。根据您的Qt版本（我假设），您可能拥有重载表格小部件项的小于方法。
from PyQt4.QtCore import Qt, QVariantfrom PyQt4.QtGui import QApplication, QTableWidget, QTableWidgetItemclass MyTableWidgetItem(QTableWidgetItem): def __lt__(self, other): if ( isinstance(other, QTableWidgetItem) ): my_value, my_ok = self.data(Qt.EditRole).toInt() other_value, other_ok = other.data(Qt.EditRole).toInt() if ( my_ok and other_ok ): return my_value < other_value return super(MyTableWidgetItem, self).__lt__(other)if ( __name__ == '__main__' ): app = None if ( QApplication.instance() is None ): app = QApplication([]) widget = QTableWidget() widget.setWindowFlags(Qt.Dialog) widget.setSortingEnabled(True) widget.setRowCount(50) widget.setColumnCount(3) for row in range(50): # create a normal QTableWidgetItem a = QTableWidgetItem() a.setText(str(row)) widget.setItem(row, 0, a) # create a proper sorted item b = QTableWidgetItem() b.setData(Qt.EditRole, QVariant(row)) widget.setItem(row, 1, b) # create a custom sorted item c = MyTableWidgetItem() c.setData(Qt.EditRole, QVariant(row)) widget.setItem(row, 2, c) widget.show() if ( app ): app.exec_()
