【問題】
想要使用Python的xlwt設置單元格的背景色。
但是不知道如何設置。
【解決過程】
1.從Working with Excel Files in Python 找到官網的：The xlwt Module，無果。
2.參考：
XLWT : Changing the Cell Background Color
試了其代碼：
|
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。
不過后來才知道，下面的代碼：
|
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
|
是可以設置背景色的。
但是很有限制。
而且對應的3是Green的意思，也是后來才知道的。
3.后來
是從
python xlwt set custom background colour of a cell
中，試了試其所用的代碼：
|
1
|
style1
=
xlwt.easyxf(
'pattern: pattern solid, fore_colour red;'
)
|
最終，經過測試，改為自己所需的代碼的：

import

#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);

對應的，上述顏色的選擇，可以參考這里：

只是當時覺得太繁瑣，沒有自己看而已。
【總結】
如上代碼所示：
- 可以通過xlwt.Pattern()然后得到pattern，設置pattern_fore_colour即可，但是顏色選擇很有限。
- 也可以通過更方便的：
- xlwt.easyxf(‘pattern: pattern solid, fore_colour ocean_blue; font: bold on;’);
- 去設置背景色。
