PyQt5：启用对 table 中的特定列进行排序

Question

我有一个包含 3 行和 2 列的 table。我正在尝试根据第一列数据对 table 进行排序。当我使用 setSortingEnabled(True) 时，它会启用对所有列的排序。我尝试了不同的方法，但没有任何帮助解决这个问题。附上示例代码供参考

from PyQt5 import QtWidgets, QtGui, QtCore
from PyQt5.QtWidgets import QWidget, QCheckBox, QApplication
from PyQt5.QtWidgets import *
from PyQt5.QtCore import *
from PyQt5.QtGui import *
import sys


class Window(QtWidgets.QMainWindow):
    def __init__(self):
        super (Window, self).__init__()
        Window.setGeometry(self, 0, 22, 480, 250)
        self.table = QtWidgets.QTableWidget(self)
        self.table.setGeometry(QtCore.QRect(10, 5, 460, 200))
        self.table.setColumnCount(3)
        horHeaders = ["seat", "material"]
        data = [("15","leather"),("18","plastic"),("20","resin")]

        self.table.setHorizontalHeaderLabels(horHeaders)
        self.table.verticalHeader().setVisible(False)
        row_number = 0
        for i in data:
            self.table.insertRow(row_number)
            self.table.setItem(row_number, 0, QTableWidgetItem(i[0]))
            self.table.setItem(row_number, 1, QTableWidgetItem(i[1])) 
            row_number += 1 
            print(i)
        self.table.setSortingEnabled(True)
        self.table.sortByColumn(0, QtCore.Qt.AscendingOrder)
        self.table.horizontalHeader().setSortIndicator(0, Qt.AscendingOrder)
        self.show()
        
if __name__ == '__main__':

    
    app = QtWidgets.QApplication(sys.argv)
    window = Window()
    window.show()
    sys.exit(app.exec_())

没有直接的方法来选择可以对哪一列进行排序，因此解决方法是覆盖第一列的列的 mouseReleaseEvent 方法，您还应该考虑到此解决方案具有次要效果，例如列移动，列选择完成等，但在这种特殊情况下，OP 不使用它们。

import sys

from PyQt5 import QtCore, QtGui, QtWidgets


class HeaderView(QtWidgets.QHeaderView):
    def mouseReleaseEvent(self, event):
        index = self.visualIndexAt(event.pos().x())
        logical_index = self.logicalIndex(index)
        if logical_index == 0:
            super().mouseReleaseEvent(event)


class Window(QtWidgets.QMainWindow):
    def __init__(self):
        super(Window, self).__init__()
        self.setGeometry(0, 22, 480, 250)
        self.table = QtWidgets.QTableWidget(self)
        self.header = HeaderView(QtCore.Qt.Horizontal)
        self.header.setSectionsClickable(True)
        self.table.setHorizontalHeader(self.header)
        self.table.setSortingEnabled(True)

        self.table.setGeometry(QtCore.QRect(10, 5, 460, 200))

        self.table.setColumnCount(3)
        horHeaders = ["1", "2", "3"]
        data = [("a", "b"), ("c", "d"), ("e", "f")]
        self.table.setHorizontalHeaderLabels(horHeaders)
        self.table.verticalHeader().hide()
        row_number = 0
        for i0, i1 in data:
            self.table.insertRow(row_number)
            self.table.setItem(row_number, 0, QtWidgets.QTableWidgetItem(i0))
            self.table.setItem(row_number, 1, QtWidgets.QTableWidgetItem(i1))
            row_number += 1

        self.table.sortByColumn(0, QtCore.Qt.AscendingOrder)


if __name__ == "__main__":

    app = QtWidgets.QApplication(sys.argv)
    window = Window()
    window.show()
    sys.exit(app.exec_())
