xlwt
1、导入模块
import xlwt
2、构造excel表
workbook = xlwt.Workbook() #返回一个工作簿对象
3、构造sheet
workbook.add_sheet('info',cell_overwrite_ok=True) #添加name为info的sheet
4、构造sheet的格式
style=xlwt.XFStyle()
1) Formatting the Contents of a Cell
fnt = xlwt.Font()
fnt.name = u'微软雅黑'
fnt.colour_index = 2
#0x01 # 字体颜色默认为黑色，此处设置字体颜色为白色， 颜色范围为：0x00-0xff,也可
以纯数字表示。
fnt.underline = True
fnt.italic = True
fnt.bold = True
fnt.height = 160 #font size:8pt
style.font = fnt
2) Setting the Background Color of a Cell
pattern = xlwt.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.pattern = pattern # Add Pattern to Style
3) Adding Borders to a Cell
border = xlwt.Borders()
border.left =xlwt.Borders.THIN
border.top =xlwt.Borders.THIN
border.right =xlwt.Borders.THIN
border.bottom =xlwt.Borders.THIN
# May be: NO_LINE, THIN, MEDIUM, DASHED, DOTTED, THICK, DOUBLE, HAIR, MEDIUM_DASHED, THIN_DASH_DOTTED,MEDIUM_DASH_DOTTED,THIN_DASH_DOT_DOTTED,MEDIUM_DASH_DOT_DOTTED, SLANTED_MEDIUM_DASH_DOTTED, or 0x00 through 0x0D.
border.left_color = 0x40
border.top_color = 0x40
border.right_color = 0x40
border.bottom_color = 0x40
style.borders =border
4) Setting the Alignment for the Contents of a Cell
alignment = xlwt.Alignment()
style.alignment.horz = HORZ_CENTER #水平居中 值为2
style.alignment.vert = VERT_CENTER #垂直居中 值为1
style.alignment.wrap = 1 # 自动换行
style.alignment = alignment
#May be: HORZ_GENERAL, HORZ_LEFT, HORZ_CENTER, HORZ_RIGHT,HORZ_FILLED,
HORZ_JUSTIFIED, HORZ_CENTER_ACROSS_SEL, HORZ_DISTRIBUTED
sheet1.col(0).width = 256*20
#默认字体0的1/256为衡量单位。默认宽度为2960，既11个字符0的宽度。256为衡量单位，20表示20个字符宽度
5) Entering a Date into a Cell
style.num_format_str = 'M/D/YY'
# Other options: D-MMM-YY, D-MMM, MMM-YY, h:mm, h:mm:ss, h:mm, h:mm:ss, M/D/YY h:mm, mm:ss, [h]:mm:ss, mm:ss.0
worksheet.write(0, 0, datetime.datetime.now(), style)
时间类型的转换，把excel中时间转成python 时间(两种方式)
xlrd.xldate_as_tuple(table.cell(2,2).value, 0) #转化为元组形式
xlrd.xldate.xldate_as_datetime(table.cell(2,2).value, 1) #直接转化为datetime对象
xlrd.xldate_as_tuple(d,0)
#d 是从excel中读取出来的浮点数
#第二个参数:有两种取值,0是以1900-01-01为基准的日期,而1是1904-01-01为基准的日期该函数返回的是一个元组,他的值类似:(year, month, day, hour, minute, nearest_second)
6) Adding a Formula to a Cell
worksheet.write(1, 0, xlwt.Formula('A1*B1'))
# Should output "10" (A1[5] * A2[2])
worksheet.write(1, 1, xlwt.Formula('SUM(A1,B1)'))
# Should output "7" (A1[5] + A2[2])
7) Merging Columns and Rows
worksheet.write_merge(0, 0, 0, 3, 'First Merge')
# Merges row 0's columns 0 through 3.
worksheet.write_merge(1, 2, 0, 3, 'Second Merge', style)
# Merges row 1 through 2's columns 0 through 3
8) Adding a Hyperlink to a Cell
worksheet.write(0,0,xlwt.Formula('HYPERLINK("http://www.google.com";"Google")'))
# Outputs the text "Google" linking to http://www.google.com
5、写入数据到sheet
sheet1.write(0,0,'ok') #在指定行列写入数据
6、保存excel
workbook.save('ok.xls') #对工作簿进行保存
