当启用排序时，在PyQt4中使用QTableWidget，将项目排序为字符串

变量=[1,2,3,4,5,11,22,33]

产生秩序

一, 11 2. 22 3. 33 4. 五,

我目前正在使用下面的代码填写表格

tableWidgetData.setItem(0, 0, QtGui.QTableWidgetItem(variable))

我已经尝试过了，因为我认为变量只能按字符串排序，因为它们是字符串

tableWidgetData.setItem(0, 0, QtGui.QTableWidgetItem(int(variable)))

但这是不可能的。我哪里出错了？

如果有任何东西在

QtGui.QTableWidgetItem

构造函数中传递变量，我必须是

QtCore.QString

ot python sring

要修复此问题，请创建自定义的

QtGui.QTableWidgetItem

，并通过overide实现check case-less-than（或者我们在python中知道的是）

导入系统随机输入从PyQt4导入QtCore、QtGui 类QCustomTableWidgetItem（QtGui.QTableWidgetItem）：定义初始值（自身，值）： super（QCustomTableWidgetItem，self）。\uuuu初始化（QtCore.QString（“%s”%value））定义（自身、其他）：如果（isinstance（其他，QCustomTableWidgetItem））： selfDataValue=float（self.data（QtCore.Qt.EditRole.toString（）） otherDataValue=float（other.data（QtCore.Qt.EditRole.toString（））返回selfDataValue如果有任何东西在
