Question

我有一个脚本，它接受一个pandas数据帧并将其分成几百个块并将每个块保存为单独的excel文件。每个块将具有相同数量的列，但行数会有所不同。我已经想出如何使用openpyxl将所有其他必要的格式应用于这些文件，但我还没有确定应用边框的最快方法。此外，我认为我只是没有正确应用边框，因为下面的代码（我怀疑不应该单独遍历每个单元格）不适用任何边框。

from openpyxl.style import Border

wb = load_workbook(filename = _fname)
ws = wb.worksheets[0]  
for _row in ws.range('A1:L'+str(ws.get_highest_row() ) ):
    for _cell in _row:
            _cell.style.borders.left.border_style = Border.BORDER_THIN
            _cell.style.borders.right.border_style = Border.BORDER_THIN
            _cell.style.borders.top.border_style = Border.BORDER_THIN
            _cell.style.borders.bottom.border_style = Border.BORDER_THIN
wb.save(_fname)

所以这段代码可以运行，但它不会应用我期望的边框（excel中的默认边框），而且它需要比我更喜欢的步骤。我的期望是我应该能够做到这样的事情：

from openpyxl.style import Border

wb = load_workbook(filename = _fname)
ws = wb.worksheets[0]

_range = ws.some_range_func('A1:L'+str(ws.get_highest_row() ) ):
    _range.style.borders.all_borders = Borders.BORDER_THIN

此功能是否存在？如果没有，有人可以这么好，至少解释如何应用默认边框样式而不是这个稍厚的边框？ Border.BORDER_THICK，Border.BORDER_MEDIUM，Border.BORDER_THIN或Border.BORDER_HAIR似乎都没有。

谢谢！

Answer 1

可能这很方便：

from openpyxl.reader.excel import load_workbook
from openpyxl.style import Border

def set_border(ws, cell_range):
    rows = ws.range(cell_range)
    for row in rows:
        row[0].style.borders.left.border_style = Border.BORDER_THIN
        row[-1].style.borders.right.border_style = Border.BORDER_THIN
    for c in rows[0]:
        c.style.borders.top.border_style = Border.BORDER_THIN
    for c in rows[-1]:
        c.style.borders.bottom.border_style = Border.BORDER_THIN

#usage example:
ws = load_workbook('example.xlsx').get_active_sheet()
set_broder(ws, "C3:H10")

它的表现相当快。

Answer 2

@ user698585你的方法似乎不错，但它不再起作用，因为openpyxl的当前版本改变了实现。所以这应该更新为例如。

    ws.cell(row=1, column=1).style.border.top.border_style = borders.BORDER_MEDIUM

但会导致错误，即不允许更改样式。作为一种解决方法，我只是定义了一个专用样式，但它们只是现有样式和边框定义的重复 - 不是那么好的解决方案，只有当你知道哪个样式有更改的单元格时才有效。

    border_style = Style(font=Font(name='Console', size=10, bold=False,
                         color=Color(openpyxl.styles.colors.BLACK)),
                         fill=PatternFill(patternType='solid', fgColor=Color(rgb='00C5D9F1')),
                         border=Border(bottom=Side(border_style='medium', color=Color(rgb='FF000000'))))

Answer 3

适用于openpyxl 2.3.5的决定

from openpyxl.styles import Border, Side

def set_border(ws, cell_range):
    border = Border(left=Side(border_style='thin', color='000000'),
                right=Side(border_style='thin', color='000000'),
                top=Side(border_style='thin', color='000000'),
                bottom=Side(border_style='thin', color='000000'))

    rows = ws.iter_rows(cell_range)
    for row in rows:
        for cell in row:
            cell.border = border

set_border(worksheet, 'A5:C10')

Answer 4

@Karimov有一个稍作修改的答案
下面是您的代码应如何

    def __set_border__(self, ws, cell_range):
        border = Border(left=Side(border_style='thin', color='000000'),
                    right=Side(border_style='thin', color='000000'),
                    top=Side(border_style='thin', color='000000'),
                    bottom=Side(border_style='thin', color='000000'))

        rows = ws[cell_range]
        for row in rows:
            for cell in row:
                cell.border = border

Answer 5

如果您需要为pandas excel数据帧设置样式（边框...），我的fork刚刚合并为master https://github.com/pydata/pandas/pull/2370#issuecomment-10898427

至于你的边界问题。一次设置所有边框不会在openpyxl中工作。

In [34]: c.style.borders.all_borders.border_style = openpyxl.style.Border.BORDER_THIN

In [36]: c.style
'Calibri':11:False:False:False:False:'none':False:'FF000000':'none':0:'FFFFFFFF':'FF000000':'none':'FF000000':'none':'FF000000':'none':'FF000000':'none':'FF000000':'none':'FF000000':0:'thin':'FF000000':'none':'FF000000':'none':'FF000000':'none':'FF000000':'none':'FF000000':'general':'bottom':0:False:False:0:'General':0:'inherit':'inherit'

单独设置（'thin'：'FF000000'）

In [37]: c.style.borders.top.border_style = openpyxl.style.Border.BORDER_THIN

In [38]: c.style
Out[38]: 'Calibri':11:False:False:False:False:'none':False:'FF000000':'none':0:'FFFFFFFF':'FF000000':'none':'FF000000':'none':'FF000000':'thin':'FF000000':'none':'FF000000':'none':'FF000000':0:'thin':'FF000000':'none':'FF000000':'none':'FF000000':'none':'FF000000':'none':'FF000000':'general':'bottom':0:False:False:0:'General':0:'inherit':'inherit'

也许是openpyxl中的一个错误。但是没有什么大不了的，只需在功能中设置底部，顶部，左侧，右侧

Answer 6

发生了相同的问题，但由于折旧，找不到任何可解决此问题的解决方案（2019年）。我在下面有一些可行的方法..可能更好，但可以满足所有意图和目的。

def set_border(ws, cell_range):
    rows = ws[cell_range]
    for row in rows:
        if row == rows[0][0] or row == rows[0][-1] or row == rows[-1][0] or row == rows[-1][-1]:
            pass
        else:
            row[0].border = Border(left=Side(style='thin'))
            row[-1].border = Border(right=Side(style='thin'))
        for c in rows[0]:
            c.border = Border(top=Side(style='thin'))
        for c in rows[-1]:
            c.border = Border(bottom=Side(style='thin'))
    rows[0][0].border = Border(left=Side(style='thin'), top=Side(style='thin'))
    rows[0][-1].border = Border(right=Side(style='thin'), top=Side(style='thin'))
    rows[-1][0].border = Border(left=Side(style='thin'), bottom=Side(style='thin'))
    rows[-1][-1].border = Border(right=Side(style='thin'), bottom=Side(style='thin'))

Answer 7

对于openpyxl == 3.0.5，以更Python的方式：

from openpyxl.styles import Border, Side

def set_border(ws, cell_range):
    thin = Side(border_style="thin", color="000000")
    for row in ws[cell_range]:
        for cell in row:
            cell.border = Border(top=thin, left=thin, right=thin, bottom=thin)

set_border(worksheet, 'A5:C10')

Answer 8

def set_border(ws, cell_range, style='thin'):
rows = ws[cell_range]
for row in rows:
    temp_row = copy(row[0].border)
    row[0].border = Border(left=Side(style=style), right=temp_row.right, top=temp_row.top, bottom=temp_row.bottom)

    temp_row = copy(row[-1].border)
    row[-1].border = Border(right=Side(style=style), left=temp_row.left, top=temp_row.top, bottom=temp_row.bottom)
for c in rows[0]:
    temp_row = copy(c.border)
    c.border = Border(top=Side(style=style), left=temp_row.left, bottom=temp_row.bottom, right=temp_row.right)
for c in rows[-1]:
    temp_row = copy(c.border)
    c.border = Border(bottom=Side(style=style), left=temp_row.left, top=temp_row.top, right=temp_row.right)

这会保留侧面的现有边框，您还可以设置边框的样式

Answer 9

似乎没有内置的任务，我们必须自己做一些步骤，如：

#need make conversion from alphabet to number due to range function
def A2N(s,e):
    return range(ord(s), ord(e)+1)
#B1 is the border you defined
#Assume you trying border A1-Q1 ... A3-Q3
X = A2N('A','Q')
#print X    
your_desired_sheet_range_rows = range(1,4)
#need two loop to go through cells
for row in your_desired_sheet_rows:
    for col in X:
        ca = chr(col)
        sheet[ca+str(row)].border=B1

使用openpyxl为范围内的所有单元格应用边框
