python之如何复制excel模板并保留表格样式

 import openpyxl
 df=openpyxl.load_workbook('costDay.xlsx')
 # wb=copy(df)
 df.save('de.xlsx')

from xlrd import open_workbook
df=open_workbook('costDay.xlsx',formatting_info=True)

# 定义一个函数，把df写入excel的指定位置
# start_line：excel写入的起始行
# data_df：要写入的数组
def write_excel(filepath,start_line, data_df):
    # 打开待写入文件
    filePath =filepath
    tableAll = op.load_workbook(filePath)
    table1 = tableAll['Sheet1']
    for c in range(data_df.shape[1]):
        for r in range(data_df.shape[0]):
            table1.cell(row=start_line, column=c + 2).value = data_df.columns[c]
            data = data_df.iloc[r, c]
            table1.cell(row=start_line + r + 2, column=c + 2).value = data
            # 以第一列复制格式
            table1.cell(row=start_line + r + 2, column=c + 2).font = copy(table1.cell(row=start_line + r + 2, column=1).font)
            table1.cell(row=start_line + r + 2, column=c + 2).fill = copy(table1.cell(row=start_line + r + 2, column=1).fill)
            table1.cell(row=start_line + r + 2, column=c + 2).border = copy(table1.cell(row=start_line + r + 2, column=1).border)
            table1.cell(row=start_line + r + 2, column=c + 2).number_format = copy(table1.cell(row=start_line + r + 2, column=1).number_format)
            table1.cell(row=start_line + r + 2, column=c + 2).protection = copy(table1.cell(row=start_line + r + 2, column=1).protection)
            table1.cell(row=start_line + r + 2, column=c + 2).alignment = copy(table1.cell(row=start_line + r + 2, column=1).alignment)
    tableAll.save(filePath)
