Python中xlwt解析
xlwt
1、導入模塊
import xlwt
2、構造excel表
workbook = xlwt.Workbook() #返回一個工作簿對象
3、構造sheet
workbook.add_sheet(‘info‘,cell_overwrite_ok=True) #添加name為info的sheet
4、構造sheet的格式
style=xlwt.XFStyle()
1) Formatting the Contents of a Cell
fnt = xlwt.Font()
fnt.name = u‘微軟雅黑‘
fnt.colour_index = 2
#0x01 # 字體顏色默認為黑色，此處設置字體顏色為白色， 顏色範圍為：0x00-0xff,也可
以純數字表示。
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 值為2
style.alignment.vert = VERT_CENTER #垂直居中 值為1
style.alignment.wrap = 1 # 自動換行
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
#默認字體0的1/256為衡量單位。默認寬度為2960，既11個字符0的寬度。256為衡量單位，20表示20個字符寬度
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)
時間類型的轉換，把excel中時間轉成python 時間(兩種方式)
xlrd.xldate_as_tuple(table.cell(2,2).value, 0) #轉化為元組形式
xlrd.xldate.xldate_as_datetime(table.cell(2,2).value, 1) #直接轉化為datetime對象
xlrd.xldate_as_tuple(d,0)
#d 是從excel中讀取出來的浮點數
#第二個參數:有兩種取值,0是以1900-01-01為基準的日期,而1是1904-01-01為基準的日期該函數返回的是一個元組,他的值類似:(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、寫入數據到sheet
sheet1.write(0,0,‘ok‘) #在指定行列寫入數據
6、保存excel
workbook.save(‘ok.xls‘) #對工作簿進行保存
