xls4-想要使用Python的xlwt设置单元格的背景色。

xls4-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：

1 2 3 4 5 6 7 8 9 10

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：

1 2 3 4 5 6

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：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30

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：

摘录如下：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61

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：

1 2 3 4 5 6 7 8 9 10

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。
