1、新建一個run.py(要執行的檔案)，程式碼如下
# -*- coding: utf-8 -*- """ 檔名稱: run.py 檔案建立時間: 2021/8/10 11:08 軟體名稱: PyCharm 檔案作者: 黃氏 """ import sys from PySide6 import QtCore from PySide6.QtWidgets import QApplication import pandas as mypd # 匯入所畫的介面 from tabledemo import * # 自定義類 class Excel_Table(QMainWindow, Ui_MainWindow): def __init__(self): super().__init__() self.setupUi(self) self.excelButton.clicked.connect(self.Open_Excel_File) # connect作用就是執行某個函式 self.saveButton.clicked.connect(self.Excel_Save) def Open_Excel_File(self): excel_name= QFileDialog.getOpenFileName(self, '選擇檔案', '', 'Excel files(*.xlsx)') # 過濾出xlsx格式的檔案 self.path_excel_name = excel_name[0] print("Excel文件的路徑： ", self.path_excel_name) if len(self.path_excel_name) > 0: self.Read_Excel_Data() self.Table_Initialize() # 讀取 EXCEL 文件的資料 def Read_Excel_Data(self): self.excel_file= mypd.read_excel(self.path_excel_name) # 獲取資料的行標籤與列標籤 self.columns = self.excel_file.columns self.rows = self.excel_file.index # 定義表格的初始化引數 def Table_Initialize(self): self.tableWidget.setHorizontalScrollBarPolicy(QtCore.Qt.ScrollBarAlwaysOn) self.tableWidget.setRowCount(len(self.rows)) # 設定表格的行數 self.tableWidget.setColumnCount(len(self.columns)) # 設定表格的列數 self.tableWidget.setHorizontalHeaderLabels(self.columns) # 設定表格的列標籤 self.tableWidget.setGeometry(QtCore.QRect(223,120,1000,800)) # 重新設定表格區域的大小 # 將 EXCEL 文件的資料顯示在表格中 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() # 列寬隨著內容調整 self.tableWidget.resizeRowsToContents() # 行寬隨著內容調整 self.tableWidget.setAlternatingRowColors(True) # 表格的顏色交錯顯示 self.tableWidget.itemChanged.connect(self.Table_Data_Change) # 將表格中單元格改變時，觸發 Table_Data_Change 事件 # 當表格的內容改變時獲取內容 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]形式會報銷
def Excel_Save(self): self.excel_file.to_excel(self.path_excel_name, index=False) if __name__ == '__main__': app = QApplication(sys.argv) excelTable = Excel_Table() excelTable.show() sys.exit(app.exec())
2、新建一個ui的python文件，檔案tabledemo.py程式碼如下(我是用QtDesigner設計，通過PyUIC命令轉換過來的)
