使用python在excel中复制和粘贴数据保留源格式

问题描述

我想使用源格式（单元格图案、单元格边框、字体样式、字体颜色、字体大小、页眉和页脚）将数据从工作簿中的一张工作表复制到工作簿中的另一张工作表。 这是我使用的代码，它可以工作，但无法保持源格式。如果你们有任何可能对本主题有所帮助的想法，那就太好了。

源代码：

import openpyxl as xl;
from copy import copy
wb1 = xl.load_workbook('C:\\Users\\high.xlsx')
ws1 = wb1.active
filename = 'C:\\Users\\3.0.xlsx'
wb2 = xl.load_workbook(filename)
ws2 = wb2['Session']


mr = ws1.max_row
mc = ws1.max_column
mr2 = ws2.max_row
mc2 = ws2.max_column

ws2.delete_cols(1,mc2+1)
ws2.delete_rows(1,mr2+1)

for i in range (1,mr + 1):
    for j in range (1,mc + 1):

        c = ws1.cell(row = i,column = j)


        ws2.cell(row = i,column = j).value = c.value
wb2.save(str(filename))

解决方法

单元格对象上有许多属性，您可以复制这些属性，这些属性具有样式信息。尝试直接复制它们会失败，但使用复制模块可以。

样式信息也可以附加到行和列 - 它们似乎附加到 dimension objects on the worksheet。

更新：哎呀，这看起来像 already been answered - 我会把它留在这里，因为它包括行和列级别的样式。

import openpyxl as xl
from copy import copy

style_attrs = ["alignment","border","fill","font","number_format","protection"]


def cells(worksheet):
    """Return a generator for the sequence of cells in the worksheet"""
    for row in worksheet:
        for cell in row:
            yield cell


def copy_attrs(src,dst,attrs=style_attrs):
    """Copy attributes from src to dst. Attributes are shallow-copied to avoid
    TypeError: unhashable type: 'StyleProxy'"""
    for name in attrs:
        setattr(dst,name,copy(getattr(src,name)))


def copy_column_attrs(worksheet_src,worksheet_dst,attrs=style_attrs + ["width"]):
    """Copy ColumnDimension properties from worksheet_src to worksheet_dst.
    Only properties listed in attrs will be copied."""
    for column,dimensions in worksheet_src.column_dimensions.items():
        copy_attrs(
            src=dimensions,dst=worksheet_dst.column_dimensions[column],attrs=attrs,)


def copy_row_attrs(worksheet_src,attrs=style_attrs + ["height"]):
    """Copy RowDimension properties from worksheet_src to worksheet_dst.
    Only properties listed in attrs will be copied."""
    for row,dimensions in worksheet_src.row_dimensions.items():
        copy_attrs(
            src=dimensions,dst=worksheet_dst.row_dimensions[row],attrs=style_attrs + ["height"],)


def copy_cells(worksheet_src,attrs=style_attrs):
    """Copy cells from worksheet_src to worksheet_dst. If cells are styled
    then also copy the attributes listed in attrs."""
    for cell in cells(worksheet_src):
        cell_dst = worksheet_dst.cell(row=cell.row,column=cell.column)
        if cell.has_style:
            copy_attrs(cell,cell_dst,attrs=attrs)
        cell_dst.value = cell.value


def delete_worksheet_cells(worksheet):
    worksheet.delete_cols(1,worksheet.max_column + 1)
    worksheet.delete_rows(1,worksheet.max_row + 1)


wb_src = xl.load_workbook("a.xlsx")
ws_src = wb_src.active

wb_dst = xl.load_workbook("b.xlsx")
ws_dst = wb_dst.active

delete_worksheet_cells(ws_dst)
copy_column_attrs(ws_src,ws_dst)
copy_row_attrs(ws_src,ws_dst)
copy_cells(ws_src,ws_dst)
wb_dst.save("b.xlsx")
