使用Openpyxl将边框应用于单元格范围 [英] Apply Border To Range Of Cells Using Openpyxl

问题描述

我正在使用python 2.7.10和openpyxl 2.3.2，并且我是Python新手.

I am using python 2.7.10 and openpyxl 2.3.2 and I am a Python newbie.

我正在尝试将边框应用于Excel工作表中指定范围的单元格(例如C3:H10).我在下面的尝试失败，并显示以下消息:

I am attempting to apply a border to a specified range of cells in an Excel worksheet (e.g. C3:H10). My attempt below is failing with the the following message:

AttributeError:单元"对象没有属性样式".

AttributeError: 'Cell' object has no attribute 'styles'.

如何在单元格上附加边框?任何见解将不胜感激.

How do I attach a border to a cell? Any insights would be gratefully received.

我当前的代码:

import openpyxl
from openpyxl.styles import Border, Side

def set_border(ws, cell_range):
    rows = ws.iter_rows(cell_range)
    for row in rows:
        row[0].styles.borders = Border(left=Side(border_style='thin', color="FF000000"))
        row[-1].styles.borders = Border(right=Side(border_style='thin', color="FF000000"))
    for c in rows[0]:
        c.styles.borders = Border(top=Side(border_style='thin', color="FF000000"))
    for c in rows[-1]:
        c.styles.borders = Border(bottom=Side(border_style='thin', color="FF000000"))


# Example call to set_border
wb = openpyxl.load_workbook('example.xlsx')
ws = wb.get_sheet_by_name('Sheet1')

set_border(ws, "B3:H10")

推荐答案

首先将所有属性称为style(不是styles)和border(不是borders).另外，要更改边框，您应该直接设置cell.border.

First of all properties are called style (not styles) and border (not borders). Also to change border you should set cell.border directly.

除了边界逻辑存在一些问题外，由于迭代器和弯角，使它正确工作也更加复杂.这是一个粗略的版本(它很简单，但内存效率低):

Besides that you have some problems with borders logic, it's more complex to get it working correctly, because of iterators and corners. Here is a rough version (it is as simple as I could get it, but not memory efficient):

def set_border(ws, cell_range):
    rows = ws[cell_range]
    side = Side(border_style='thin', color="FF000000")

    rows = list(rows)  # we convert iterator to list for simplicity, but it's not memory efficient solution
    max_y = len(rows) - 1  # index of the last row
    for pos_y, cells in enumerate(rows):
        max_x = len(cells) - 1  # index of the last cell
        for pos_x, cell in enumerate(cells):
            border = Border(
                left=cell.border.left,
                right=cell.border.right,
                top=cell.border.top,
                bottom=cell.border.bottom
            )
            if pos_x == 0:
                border.left = side
            if pos_x == max_x:
                border.right = side
            if pos_y == 0:
                border.top = side
            if pos_y == max_y:
                border.bottom = side

            # set new border only if it's one of the edge cells
            if pos_x == 0 or pos_x == max_x or pos_y == 0 or pos_y == max_y:
                cell.border = border
