Question

我正在使用xlsxwriter创建xlsx文件，并希望保护特定的单元格（例如B2：B20范围内的所有单元格）。文档说您可以使用worksheet.protect()方法 - 它默认启用整个工作表的保护 - 然后您可以使用workbook.add_format({'locked': 0})来解锁特定单元格。但我反之亦然 - 我想只锁定特定范围的单元格，并将工作表的其余部分解锁。我怎么能这样做？

Answer 1

执行此操作的方法与Excel中的相同：set an unlock format for the entire sheet。

在Excel和XlsxWriter中，这转换为为所有列设置解锁格式。像这样：

import xlsxwriter

workbook = xlsxwriter.Workbook('protection.xlsx')
worksheet = workbook.add_worksheet()

# Create some cell formats with protection properties.
unlocked = workbook.add_format({'locked': False})
locked   = workbook.add_format({'locked': True})

# Format the worksheet to unlock all cells.
worksheet.set_column('A:XDF', None, unlocked)

# Turn worksheet protection on.
worksheet.protect()

# Write a locked and an unlocked cell.
worksheet.write('B1', 'Cell A1 is locked. It cannot be edited.')
worksheet.write('B2', 'Cell A2 is unlocked. It can be edited.')
worksheet.write('B3', 'Cell A3 is unlocked. It can be edited.')

worksheet.write('A1', 'Hello', locked  )  
worksheet.write('A2', 'Hello', unlocked)
worksheet.write('A3', 'Hello'          ) # Unlocked by default.

workbook.close()

Answer 2

您可以使用以下代码保护单页或多页Excel文件的特定单元格范围。

注意：此函数假定Excel文件已经生成。

def protectCell(excelFilePath, protectCellRange='a1:b1', sheetName = 'Sheet1'):
    ''' 
    To protect the range of cell in an Excel file.
    arguments:
        1. excelFilePath : path of excel file.
        2. protectCellRange : Range of cells to protect. default is a1:b1
        3. sheetName : name of the sheet present in Excel file. Default is Sheet1
        
        Currently it supports column from A to Z only. i.e 0 to 25 columns 
        
    '''
    protectCellRange = protectCellRange.lower() 
    temp = list(string.ascii_lowercase)
    # refer = {'a':0, 'b':1, 'c':2, 'd':3, 'e':4}
    refer = {}
    for i, item in enumerate(temp):
        refer[item] = i
        
    writer = pd.ExcelWriter(excelFilePath, engine='xlsxwriter')
    TotalDf = pd.read_excel(excelFilePath, sheet_name = None, header= None)
    for sheet in TotalDf.keys():
        if sheet == sheetName:
            df = TotalDf[sheetName]
            # workbook = xlsxwriter.Workbook('excelFilePath='./temp/protection.xlsx')
            # worksheet = workbook.add_worksheet()
            df.to_excel(writer, sheet_name = sheetName, header= False, index=False)
            workbook = writer.book
            worksheet = writer.sheets[sheetName]
            # Create some cell formats with protection properties.
            unlocked = workbook.add_format({'locked': False, 'font_size': 9, 'text_wrap': True, 'align': 'left', 'valign': 'top',})
            locked   = workbook.add_format({'locked': True, 'font_size': 9, 'text_wrap': True, 'align': 'left', 'valign': 'top',})
            
            # Format the worksheet to unlock all cells.
            worksheet.set_column('A:C', 20, unlocked)
            
            # Turn worksheet protection on.
            worksheet.protect()
            
            startPointer = protectCellRange.split(':')[0]
            endPointer = protectCellRange.split(':')[-1]
            
            if len(startPointer) < 1 or len(endPointer) < 1:
                print(f'Please specify correct cell range. Specified range is {protectCellRange}')
                return 'Failure'
            
            colRange = range(refer[startPointer[0]],refer[endPointer[0]] + 1 ) 
            rowRange = range(int(startPointer[1:]), int(endPointer[1:]) + 1 )
            for col in colRange:
                for row in rowRange:
                    c = [k for k,v in refer.items() if v == col][0].upper()
                    print(col,row)
                    try:
                        value = df[col].iloc[row-1]
                        #print(f'value is ::: {value}')
                        worksheet.write(c+str(row), value, locked, )
                    except:
                        print(f'exception in Cell: {c+str(row)}')
        else:
            df = TotalDf[sheet]
            df.to_excel(writer,sheet_name = sheet, header= False, index=False)
            workbook = writer.book
            worksheet = writer.sheets[sheet]
            wrap_format = workbook.add_format({'text_wrap': True, 'align': 'left', 'valign': 'top'})
            worksheet.set_column('A:E', 20, wrap_format)
    workbook.worksheets_objs.sort(key=lambda x: x.name)    
    writer.save()
    writer.close()  
    workbook.close()
    print(f'Excel File is protected for section {protectCellRange}')
    return 'Success'

使用所有必需的参数调用函数

protectCell(excelFilePath='./Cell_protection.xlsx',
            protectCellRange = 'A4:C7', sheetName = 'ABC')

protectCell(excelFilePath='./Cell_protection.xlsx',
                protectCellRange = 'A4:', sheetName = 'ABC')
#Range is not mentioned properly

protectCell(excelFilePath='./Cell_protection.xlsx',
                    protectCellRange = ':C7', sheetName = 'ABC')
#Range is not mentioned properly

XlsxWriter：仅锁定特定单元格
