以上是源代码，求各位大神棒棒忙？或者指导一下= =！！！我查了好久的代码，一直搞不懂，写进去就出错。。。不知道是逻辑有问题，还是怎么样！

回答问题前，我想下提几点建议，提问时，需要说清楚的几点东西：
1、你想实现什么功能，比如我要做一个自动生成工牌图片的界面程序。
2、你遇到的问题的具体描述，比如你想问程序为什么运行不起来：如果是运行了不报错，但是没有达到你预期的效果（对应代码逻辑错误），你需要把你预期的结果，和程序运行的结果说清；如果是运行之后报错（对应程序运行错误，语法错误等），你需要提供ide报错的完整文本。
3、贴代码时，尽量做到两点：（1）添加必要的注释（2）使用代码框

lightninng

从你的代码里面，我看到的可能出问题的点，一个类定义中，第一个方法一定是__init__方法，借用https://www.runoob.com/python/python-object.html这个文档的内容，__init__方法被称为类的构造函数或初始化方法，当创建了这个类的实例时就会调用该方法，当你实例化一个类时，会首先自动执行__init__方法中的内容。
另外，建议你所有界面处理的部分，都放在setupUi方法中，如以这句代码（这也是使用代码框的示例）：

app.setWindowIcon(QIcon('./image/w1.png'))

然后再__init__方法中调用setUi方法来生成界面，而不是把他放在主程序里面：

最后贴一段代码（使用PySide2编写，但是逻辑几乎完全一样）

from PySide2 import QtCore, QtGui
from PySide2.QtGui import QFont
from PySide2.QtWidgets import QApplication, QWidget, QMessageBox, QFileDialog,QGridLayout,QCheckBox,QPushButton,QLabel,QSizePolicy,QTableWidget,QTableWidgetItem,QHeaderView
    def __init__(self):
        #初始化方法
        super(MainWindow, self).__init__()

        #调用setupUi方法生成界面
        self.setupUi(self)

        #处理其他逻辑
        self.pushButton_2.setText("开始随机")
              
        self.pushButton_1.clicked.connect(self.import_file)
        self.pushButton_2.clicked.connect(lambda:self.click_random(self.pushButton_2.text()))
        self.pushButton_3.clicked.connect(self.output_file)
        self.pushButton_4.clicked.connect(self.scroll_play)
        self.pushButton_5.clicked.connect(self.show_position_window)
  
        self.tables = []
        self.data=None
        self.positions=[]

        self.icon = QtGui.QIcon()
        self.icon.addPixmap(QtGui.QPixmap(":main.ico"), QtGui.QIcon.Normal,QtGui.QIcon.Off)
        self.setWindowIcon(self.icon)
        
        self.random_thread = myThread()
        self.stop_singnal.connect(self.random_thread.stop)
        self.random_thread.shuffle_signal.connect(self.shuffle)
        self.random_thread.button_text_signal.connect(self.button_text_build)

        self.spinBox_1.valueChanged.connect(lambda:(self.init_tables(),self.click_random(self.pushButton_2.text(),True)))
        self.spinBox_2.valueChanged.connect(lambda:(self.init_tables(),self.click_random(self.pushButton_2.text(),True)))
        self.spinBox_3.valueChanged.connect(lambda:(self.init_tables(),self.click_random(self.pushButton_2.text(),True)))
        self.checkBox_1.clicked.connect(lambda:(self.init_tables(),self.click_random(self.pushButton_2.text(),True)))

你能仔细看一下我说的内容嘛
