1、新建一个run.py(要运行的文件)，代码如下
# -*- coding: utf-8 -*- """ 文件名称: run.py 文件创建时间: 2021/8/10 11:08 软件名称: PyCharm 文件作者: 黄氏 """ import sys from PySide6 import QtCore from PySide6.QtWidgets import QApplication import pandas as mypd # 导入所画的界面 from tabledemo import * # 自定义类 class Excel_Table(QMainWindow, Ui_MainWindow): def __init__(self): super().__init__() self.setupUi(self) self.excelButton.clicked.connect(self.Open_Excel_File) # connect作用就是执行某个函数 self.saveButton.clicked.connect(self.Excel_Save) def Open_Excel_File(self): excel_name = QFileDialog.getOpenFileName(self, '选择文件', '', 'Excel files(*.xlsx)') # 过滤出xlsx格式的文件 self.path_excel_name = excel_name[0] print("Excel文档的路径： ", self.path_excel_name) if len(self.path_excel_name) > 0: self.Read_Excel_Data() self.Table_Initialize() # 读取 EXCEL 文档的数据 def Read_Excel_Data(self): self.excel_file = mypd.read_excel(self.path_excel_name) # 获取数据的行标签与列标签 self.columns = self.excel_file.columns self.rows = self.excel_file.index # 定义表格的初始化参数 def Table_Initialize(self): self.tableWidget.setHorizontalScrollBarPolicy(QtCore.Qt.ScrollBarAlwaysOn) self.tableWidget.setRowCount(len(self.rows)) # 设置表格的行数 self.tableWidget.setColumnCount(len(self.columns)) # 设置表格的列数 self.tableWidget.setHorizontalHeaderLabels(self.columns) # 设置表格的列标签 self.tableWidget.setGeometry(QtCore.QRect(223,120,1000,800)) # 重新设置表格区域的大小 # 将 EXCEL 文档的数据显示在表格中 for i in range(len(self.rows)): for j in range(len(self.columns)): tstr = str(self.excel_file.iloc[i][j]) data = QTableWidgetItem(tstr) self.tableWidget.setItem(i, j, data) self.tableWidget.resizeColumnsToContents() # 列宽随着内容调整 self.tableWidget.resizeRowsToContents() # 行宽随着内容调整 self.tableWidget.setAlternatingRowColors(True) # 表格的颜色交错显示 self.tableWidget.itemChanged.connect(self.Table_Data_Change) # 将表格中单元格改变时，触发 Table_Data_Change 事件 # 当表格的内容改变时获取内容 def Table_Data_Change(self,item): text = item.text() itemrow = item.row() itemcol = item.column() self.excel_file.iloc[itemrow,itemcol] = text # 使用[i][j]形式会报销

2、新建一个ui的python文档，文件 tabledemo.py 代码如下(我是用QtDesigner设计，通过PyUIC命令转换过来的)
