我需要在Openpyxl中设置样式的建议。
我看到可以设置单元格的NumberFormat,但我还需要设置字体颜色和属性(粗体等)。有一个style.py类,但似乎我无法设置单元格的样式属性,我真的不想开始修改openpyxl源代码。
有没有人找到解决方案?

从openpyxl 1.5.7开始,我已经成功应用了以下工作表样式选项...
from openpyxl.reader.excel import load_workbook
from openpyxl.workbook import Workbook
from openpyxl.styles import Color, Fill
from openpyxl.cell import Cell
# Load the workbook...
book = load_workbook('foo.xlsx')
# define ws here, in this case I pick the first worksheet in the workbook...
# NOTE: openpyxl has other ways to select a specific worksheet (i.e. by name
# via book.get_sheet_by_name('someWorksheetName'))
ws = book.worksheets[0]
## ws is a openpypxl worksheet object
_cell = ws.cell('C1')
# Font properties
_cell.style.font.color.index = Color.GREEN
_cell.style.font.name = 'Arial'
_cell.style.font.size = 8
_cell.style.font.bold = True
_cell.style.alignment.wrap_text = True
# Cell background color
_cell.style.fill.fill_type = Fill.FILL_SOLID
_cell.style.fill.start_color.index = Color.DARKRED
# You should only modify column dimensions after you have written a cell in
# the column. Perfect world: write column dimensions once per column
#
ws.column_dimensions["C"].width = 60.0
仅供参考,您可以在openpyxl/style.py
中找到颜色的名称...我有时会使用the X11 color names
class Color(HashableObject):
"""Named colors for use in styles."""
BLACK = 'FF000000'
WHITE = 'FFFFFFFF'
RED = 'FFFF0000'
DARKRED = 'FF800000'
BLUE = 'FF0000FF'
DARKBLUE = 'FF000080'
GREEN = 'FF00FF00'
DARKGREEN = 'FF008000'
YELLOW = 'FFFFFF00'
DARKYELLOW = 'FF808000'

从openpyxl 2.0开始,设置单元格样式是通过创建新样式对象并将它们分配给单元格的属性来完成的。
有几种样式对象:Font
,PatternFill
,Border
和Alignment
。请参阅doc。
要更改单元格的样式属性,首先必须从单元格复制现有样式对象并更改属性的值,或者必须使用所需设置创建新样式对象。然后,将新样式对象分配给单元格。
将字体设置为单元格A1的粗体和斜体的示例:
from openpyxl import Workbook
from openpyxl.styles import Font
# Create workbook
wb = Workbook()
# Select active sheet
ws = wb.active()
# Select cell A1
cell = ws['A1']
# Make the text of the cell bold and italic
cell.font = cell.font.copy(bold=True, italic=True)

从openpyxl 2.0开始,样式是不可变的。
如果您有cell
,则可以(例如)通过以下方式设置粗体文字:
cell.style = cell.style.copy(font=cell.style.font.copy(bold=True))
是的,这很烦人。

from openpyxl.styles import Font
from openpyxl.styles.colors import Color
ws1['A1'].font = Font(color = "FF0000")

从openpyxl-1.7.0开始,您也可以这样做:
cell.style.fill.start_color.index = "FF124191"
我有一些辅助函数可以在给定的cell
上设置样式 - 例如页眉,页脚等。

这似乎已经改变了几次。我正在使用openpyxl 2.5.0,我能够以这种方式设置删除选项:
new_font = copy(cell.font)
new_font.strike = True
cell.font = new_font
似乎早期版本(1.9到2.4?)在字体上有copy
方法,现在已弃用并引发警告:
cell.font = cell.font.copy(strike=True)
最多1.8的版本有可变字体,所以你可以这样做:
cell.font.strike=True
现在出现错误。

赞openpyxl doc说:
这是一个开源项目,由志愿者在业余时间维护。这可能意味着您想要的特定功能或功能缺失。
我检查了openpyxl源代码,发现:
直到openpyxl 1.8.x,样式是可变的。他们的属性可以像这样直接分配:
from openpyxl.workbook import Workbook
from openpyxl.style import Color
wb = Workbook()
ws = wb.active
ws['A1'].style.font.color.index = Color.RED
然而,从openpyxl 1.9开始,样式是不可变的。
样式在对象之间共享,一旦分配,就无法更改。这可以阻止不必要的副作用,例如更改大量单元格的样式,而不是只有一个。
要创建新的样式对象,您可以直接指定它,或者使用新属性从现有单元格样式中复制一个,回答问题作为示例(原谅我的中文英文):
from openpyxl.styles import colors
from openpyxl.styles import Font, Color
from openpyxl import Workbook
wb = Workbook()
ws = wb.active
a1 = ws['A1']
d4 = ws['D4']
# create a new style with required attributes
ft_red = Font(color=colors.RED)
a1.font = ft_red
# you can also do it with function copy
ft_red_bold = ft_red.copy(bold=True)
# you can copy from a cell's style with required attributes
ft_red_sigle_underline = a1.font.copy(underline="single")
d4.font = ft_red_bold
# apply style to column E
col_e = ws.column_dimensions['E']
col_e.font = ft_red_sigle_underline
一个小区' style包含以下属性:font,fill,border,alignment,protection和number_format。检查openpyxl.styles
。
它们是相似的,应该创建为一个对象,除了number_format,它的值是string
类型。
有一些预定义的数字格式,数字格式也可以用字符串类型定义。检查openpyxl.styles.numbers
。
from openpyxl.styles import numbers
# use pre-defined values
ws.cell['T49'].number_format = numbers.FORMAT_GENERAL
ws.cell(row=2, column=4).number_format = numbers.FORMAT_DATE_XLSX15
# use strings
ws.cell['T57'].number_format = 'General'
ws.cell(row=3, column=5).number_format = 'd-mmm-yy'
ws.cell['E5'].number_format = '0.00'
ws.cell['E50'].number_format = '0.00%'
ws.cell['E100'].number_format = '_ * #,##0_ ;_ * -#,##0_ ;_ * "-"??_ ;_ @_ '

sheet.cell.font = Font(size=23, underline='single', color='FFBB00', bold=True, italic=True)
完整代码:
import openpyxl # Connect the library
from openpyxl import Workbook
from openpyxl.styles import PatternFill # Connect cell styles
from openpyxl.workbook import Workbook
from openpyxl.styles import Font, Fill # Connect styles for text
from openpyxl.styles import colors # Connect colors for text and cells
wb = openpyxl.Workbook() # Create book
work_sheet = wb.create_sheet(title='Testsheet') # Created a sheet with a name and made it active
work_sheet['A1'] = 'Test text'
work_sheet_a1 = work_sheet['A5'] # Created a variable that contains cell A1 with the existing text
work_sheet_a1.font = Font(size=23, underline='single', color='FFBB00', bold=True,
italic=True) # We apply the following parameters to the text: size - 23, underline, color = FFBB00 (text color is specified in RGB), bold, oblique. If we do not need a bold font, we use the construction: bold = False. We act similarly if we do not need an oblique font: italic = False.
# Important:
# if necessary, the possibility of using standard colors is included in the styles, but the code in this case will look different:
work_sheet_a1.font = Font(size=23, underline='single', color=colors.RED, bold=True,
italic=True) # what color = colors.RED — color prescribed in styles
work_sheet_a1.fill = PatternFill(fill_type='solid', start_color='ff8327',
end_color='ff8327') # This code allows you to do design color cells
