PySide6读取EXCLE文档
作者：互联网
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

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

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
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)
