【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：
|
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：

#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 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：

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。
