【已解决】Python中使用xlwt设置cell的背景色

【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:

?

1

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:

importxlwt;

#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:

importxlwt

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。
