【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：

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 = """\ aqua 0x31 black 0x08 blue 0x0C blue_gray 0x36 bright_green 0x0B brown 0x3C coral 0x1D cyan_ega 0x0F dark_blue 0x12 dark_blue_ega 0x12 dark_green 0x3A dark_green_ega 0x11 dark_purple 0x1C dark_red 0x10 dark_red_ega 0x10 dark_teal 0x38 dark_yellow 0x13 gold 0x33 gray_ega 0x17 gray25 0x16 gray40 0x37 gray50 0x17 gray80 0x3F green 0x11 ice_blue 0x1F indigo 0x3E ivory 0x1A lavender 0x2E light_blue 0x30 light_green 0x2A light_orange 0x34 light_turquoise 0x29 light_yellow 0x2B lime 0x32 magenta_ega 0x0E ocean_blue 0x1E olive_ega 0x13 olive_green 0x3B orange 0x35 pale_blue 0x2C periwinkle 0x18 pink 0x0E plum 0x3D purple_ega 0x14 red 0x0A rose 0x2D sea_green 0x39 silver_ega 0x16 sky_blue 0x28 tan 0x2F teal 0x15 teal_ega 0x15 turquoise 0x0F violet 0x14 white 0x09 yellow 0x0D"""
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。
