在python中实现将excel1文件的第二个页签复制到excel2文件的第二个页签，需要注意合并单元格与样式问题

实现这个功能可以使用Python中的`openpyxl`库，具体代码如下：

from openpyxl import load_workbook
from openpyxl.utils import range_boundaries
from openpyxl.styles import PatternFill, Border, Side, Alignment, Protection, Font

# 加载excel1文件和excel2文件
wb1 = load_workbook('excel1.xlsx')
wb2 = load_workbook('excel2.xlsx')

# 获取excel1的第二个页签和excel2的第二个页签
ws1 = wb1.worksheets[1]
ws2 = wb2.worksheets[1]

# 遍历excel1的第二个页签中的所有单元格
for row in ws1.iter_rows():
    for cell in row:
        # 获取单元格的值、样式、合并单元格信息
        value = cell.value
        fill = cell.fill
        border = cell.border
        font = cell.font
        alignment = cell.alignment
        protection = cell.protection
        merge_coord = None
        if cell.coordinate in ws1.merged_cells:
            merge_coord = range_boundaries(cell.coordinate)

        # 在excel2的第二个页签中复制单元格的值、样式、合并单元格信息
        new_cell = ws2[cell.coordinate]
        new_cell.value = value
        new_cell.fill = PatternFill(start_color=fill.start_color.index, end_color=fill.end_color.index, fill_type=fill.fill_type)
        new_cell.border = Border(left=Side(border_style=border.left.style, color=border.left.color.index),
                                 right=Side(border_style=border.right.style, color=border.right.color.index),
                                 top=Side(border_style=border.top.style, color=border.top.color.index),
                                 bottom=Side(border_style=border.bottom.style, color=border.bottom.color.index),
                                 diagonal=Side(border_style=border.diagonal.style, color=border.diagonal.color.index),
                                 diagonal_direction=border.diagonal_direction,
                                 outline=border.outline,
                                 vertical=border.vertical,
                                 horizontal=border.horizontal)
        new_cell.font = Font(name=font.name, size=font.size, bold=font.bold, italic=font.italic, vertAlign=font.vertAlign,
                             underline=font.underline, strike=font.strike, color=font.color.index, scheme=font.scheme)
        new_cell.alignment = Alignment(horizontal=alignment.horizontal, vertical=alignment.vertical, text_rotation=alignment.textRotation,
                                        wrap_text=alignment.wrapText, shrink_to_fit=alignment.shrinkToFit, indent=alignment.indent,
                                        relative_indent=alignment.relativeIndent, justify_last_line=alignment.justifyLastLine,
                                        reading_order=alignment.readingOrder, merge_cell=alignment.mergeCell)
        new_cell.protection = Protection(locked=protection.locked, hidden=protection.hidden)

        # 复制合并单元格信息
        if merge_coord:
            ws2.merge_cells(start_row=merge_coord[0], start_column=merge_coord[1], end_row=merge_coord[2], end_column=merge_coord[3])

# 保存excel2文件
wb2.save('excel2.xlsx')

这段代码中，首先使用`load_workbook`函数分别加载excel1和excel2文件，然后获取excel1的第二个页签和excel2的第二个页签，遍历excel1的第二个页签中的所有单元格，逐个复制单元格的值、样式、合并单元格信息到excel2的第二个页签中，最后保存excel2文件。在复制样式时，需要注意将`openpyxl.styles`中的样式属性转换成相应的属性对象，例如`PatternFill`、`Border`、`Font`、`Alignment`和`Protection`。
