在Openpyxl中设置样式

Question

我需要有关在Openpyxl中设置样式的建议。

我看到可以设置单元格的NumberFormat，但是我还需要设置字体颜色和属性（粗体等）。有一个style.py类，但是似乎我无法设置单元格的style属性，而且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版本1.5.7开始，我已成功应用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。有时我会从X11颜色名称中添加其他颜色

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'
