【已解决】Python中使用xlwt设置cell的背景色

Python crifan 18119浏览 0评论

【问题】

想要使用Python的xlwt设置单元格的背景色。

但是不知道如何设置。

【解决过程】

1.从Working with Excel Files in Python 找到官网的:The xlwt Module,无果。

2.参考:

XLWT : Changing the Cell Background Color

试了其代码:

badBG = xlwt.Pattern()
badBG.SOLID_PATTERN = 0x34
badBG.NO_PATTERN = 0x34
badBG.pattern_fore_colour = 0x34
badBG.pattern_back_colour = 0x34

badFontStyle = xlwt.XFStyle()
badFontStyle.Pattern = badBG

sheet1.write(1,1,'hello world', badFontStyle) 

未果。

不过后来才知道,下面的代码:

badBG = xlwt.Pattern()
badBG.pattern = badBG.SOLID_PATTERN
badBG.pattern_fore_colour = 3

badFontStyle = xlwt.XFStyle()
badFontStyle.pattern = badBG 

是可以设置背景色的。

但是很有限制。

而且对应的3是Green的意思,也是后来才知道的。

 

3.后来

是从

python xlwt set custom background colour of a cell

中,试了试其所用的代码:

style1 = xlwt.easyxf('pattern: pattern solid, fore_colour red;')

最终,经过测试,改为自己所需的代码的:

import xlwt;

    #styleBlueBkg = xlwt.easyxf('font: color-index red, bold on');
    #styleBlueBkg = xlwt.easyxf('font: background-color-index red, bold on');
    #styleBlueBkg = xlwt.easyxf('pattern: pattern solid, fore_colour red;');
    #styleBlueBkg = xlwt.easyxf('pattern: pattern solid, fore_colour blue;');
    #styleBlueBkg = xlwt.easyxf('pattern: pattern solid, fore_colour light_blue;');
    #styleBlueBkg = xlwt.easyxf('pattern: pattern solid, fore_colour pale_blue;');
    #styleBlueBkg = xlwt.easyxf('pattern: pattern solid, fore_colour dark_blue;');
    #styleBlueBkg = xlwt.easyxf('pattern: pattern solid, fore_colour dark_blue_ega;');
    #styleBlueBkg = xlwt.easyxf('pattern: pattern solid, fore_colour ice_blue;');
    styleBlueBkg = xlwt.easyxf('pattern: pattern solid, fore_colour ocean_blue; font: bold on;'); # 80% like
    #styleBlueBkg = xlwt.easyxf('pattern: pattern solid, fore_colour sky_blue;');
    
    
    #blueBkgFontStyle = xlwt.XFStyle()
    #blueBkgFontStyle.Pattern = blueBackgroundPattern;
    #styleBlueBkg = blueBkgFontStyle;
    
    styleBold   = xlwt.easyxf('font: bold on');
    
    wb = xlwt.Workbook();
    ws = wb.add_sheet('realPropertyInfo');
    
    ws.write(0, 0, "Sequence",  styleBlueBkg);
    ws.write(0, 1, "MapID",     styleBlueBkg);
    ws.write(0, 2, "Owner1",    styleBold);
    ws.write(0, 3, "Owner2",    styleBold);
    
    wb.save(excelFilename);

对应的,上述颜色的选择,可以参考这里:

https://secure.simplistix.co.uk/svn/xlwt/trunk/xlwt/Style.py

摘录如下:

# Text values for colour indices. "grey" is a synonym of "gray".
# The names are those given by Microsoft Excel 2003 to the colours
# in the default palette. There is no great correspondence with
# any W3C name-to-RGB mapping.
_colour_map_text = """\

4.后来才发现,其实,上述的方法,就是前面在

Setting the Background Color of a Cell

所介绍的内容:

import xlwt
workbook = xlwt.Workbook()
worksheet = workbook.add_sheet('My Sheet')
pattern = xlwt.Pattern() # Create the Pattern
pattern.pattern = xlwt.Pattern.SOLID_PATTERN # May be: NO_PATTERN, SOLID_PATTERN, or 0x00 through 0x12
pattern.pattern_fore_colour = 5 # May be: 8 through 63. 0 = Black, 1 = White, 2 = Red, 3 = Green, 4 = Blue, 5 = Yellow, 6 = Magenta, 7 = Cyan, 16 = Maroon, 17 = Dark Green, 18 = Dark Blue, 19 = Dark Yellow , almost brown), 20 = Dark Magenta, 21 = Teal, 22 = Light Gray, 23 = Dark Gray, the list goes on...
style = xlwt.XFStyle() # Create the Pattern
style.pattern = pattern # Add Pattern to Style
worksheet.write(0, 0, 'Cell Contents', style)
workbook.save('Excel_Workbook.xls')

只是当时觉得太繁琐,没有自己看而已。

 

【总结】

如上代码所示:

  • 可以通过xlwt.Pattern()然后得到pattern,设置pattern_fore_colour即可,但是颜色选择很有限。
  • 也可以通过更方便的:
    • xlwt.easyxf(‘pattern: pattern solid, fore_colour ocean_blue; font: bold on;’);
    • 去设置背景色。
