关于写excel的格式控制，比如颜色等等

import xlwt

from datetime import datetime

font0 = xlwt.Font()

font0.name = 'Times New Roman'

font0.colour_index = 2

font0.bold = True

style0 = xlwt.XFStyle()

style0.font = font0

style1 = xlwt.XFStyle()

style1.num_format_str = 'D-MMM-YY'

wb = xlwt.Workbook()

ws = wb.add_sheet('A Test Sheet')

ws.write(0, 0, 'Test', style0)

ws.write(1, 0, datetime.now(), style1)

ws.write(2, 0, 1)

ws.write(2, 1, 1)

ws.write(2, 2, xlwt.Formula("A3+B3"))

wb.save('example.xls')

Examples Generating Excel Documents Using Python’s xlwt

Here are some simple examples using Python’s xlwt library to dynamically generate Excel documents.

Please note a useful alternative may be ezodf, which allows you to generate ODS (Open Document Spreadsheet) files for LibreOffice / OpenOffice. You can check them out at:http://packages.python.org/ezodf/index.html

The Simplest Example

import xlwt

workbook = xlwt.Workbook(encoding = 'ascii')

worksheet = workbook.add_sheet('My Worksheet')

worksheet.write(0, 0, label = 'Row 0, Column 0 Value')

workbook.save('Excel_Workbook.xls')

Formatting the Contents of a Cell

import xlwt

workbook = xlwt.Workbook(encoding = 'ascii')

worksheet = workbook.add_sheet('My Worksheet')

font = xlwt.Font() # Create the Font

font.name = 'Times New Roman'

font.bold = True

font.underline = True

font.italic = True

style = xlwt.XFStyle() # Create the Style

style.font = font # Apply the Font to the Style

worksheet.write(0, 0, label = 'Unformatted value')

worksheet.write(1, 0, label = 'Formatted value', style) # Apply the Style to the Cell

workbook.save('Excel_Workbook.xls')

Attributes of the Font Object

font.bold = True # May be: True, False

font.italic = True # May be: True, False

font.struck_out = True # May be: True, False

font.underline = xlwt.Font.UNDERLINE_SINGLE # May be: UNDERLINE_NONE, UNDERLINE_SINGLE, UNDERLINE_SINGLE_ACC, UNDERLINE_DOUBLE, UNDERLINE_DOUBLE_ACC

font.escapement = xlwt.Font.ESCAPEMENT_SUPERSCRIPT # May be: ESCAPEMENT_NONE, ESCAPEMENT_SUPERSCRIPT, ESCAPEMENT_SUBSCRIPT

font.family = xlwt.Font.FAMILY_ROMAN # May be: FAMILY_NONE, FAMILY_ROMAN, FAMILY_SWISS, FAMILY_MODERN, FAMILY_SCRIPT, FAMILY_DECORATIVE

font.charset = xlwt.Font.CHARSET_ANSI_LATIN # May be: CHARSET_ANSI_LATIN, CHARSET_SYS_DEFAULT, CHARSET_SYMBOL, CHARSET_APPLE_ROMAN, CHARSET_ANSI_JAP_SHIFT_JIS, CHARSET_ANSI_KOR_HANGUL, CHARSET_ANSI_KOR_JOHAB, CHARSET_ANSI_CHINESE_GBK, CHARSET_ANSI_CHINESE_BIG5, CHARSET_ANSI_GREEK, CHARSET_ANSI_TURKISH, CHARSET_ANSI_VIETNAMESE, CHARSET_ANSI_HEBREW, CHARSET_ANSI_ARABIC, CHARSET_ANSI_BALTIC, CHARSET_ANSI_CYRILLIC, CHARSET_ANSI_THAI, CHARSET_ANSI_LATIN_II, CHARSET_OEM_LATIN_I

font.colour_index = ?

font.get_biff_record = ?

font.height = 0x00C8 # C8 in Hex (in decimal) = 10 points in height.

font.name = ?

font.outline = ?

font.shadow = ?

Setting the Width of a Cell

import xltw

workbook = xlwt.Workbook()

worksheet = workbook.add_sheet('My Sheet')

worksheet.write(0, 0, 'My Cell Contents')

worksheet.col(0).width = 3333 # 3333 = 1" (one inch).

workbook.save('Excel_Workbook.xls')

Entering a Date into a Cell

import xlwt

import datetime

workbook = xlwt.Workbook()

worksheet = workbook.add_sheet('My Sheet')

style = xlwt.XFStyle()

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)

workbook.save('Excel_Workbook.xls')

Adding a Formula to a Cell

import xlwt

workbook = xlwt.Workbook()

worksheet = workbook.add_sheet('My Sheet')

worksheet.write(0, 0, 5) # Outputs 5

worksheet.write(0, 1, 2) # Outputs 2

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])

workbook.save('Excel_Workbook.xls')

Adding a Hyperlink to a Cell

import xlwt

workbook = xlwt.Workbook()

worksheet = workbook.add_sheet('My Sheet')

worksheet.write(0, 0, xlwt.Formula('HYPERLINK("http://www.google.com";"Google")')) # Outputs the text "Google" linking to http://www.google.com

workbook.save('Excel_Workbook.xls')

Merging Columns and Rows

import xlwt

workbook = xlwt.Workbook()

worksheet = workbook.add_sheet('My Sheet')

worksheet.write_merge(0, 0, 0, 3, 'First Merge') # Merges row 0's columns 0 through 3.

font = xlwt.Font() # Create Font

font.bold = True # Set font to Bold

style = xlwt.XFStyle() # Create Style

style.font = font # Add Bold Font to Style

worksheet.write_merge(1, 2, 0, 3, 'Second Merge', style) # Merges row 1 through 2's columns 0 through 3.

workbook.save('Excel_Workbook.xls')

Setting the Alignment for the Contents of a Cell

import xlwt

workbook = xlwt.Workbook()

worksheet = workbook.add_sheet('My Sheet')

alignment = xlwt.Alignment() # Create Alignment

alignment.horz = xlwt.Alignment.HORZ_CENTER # May be: HORZ_GENERAL, HORZ_LEFT, HORZ_CENTER, HORZ_RIGHT, HORZ_FILLED, HORZ_JUSTIFIED, HORZ_CENTER_ACROSS_SEL, HORZ_DISTRIBUTED

alignment.vert = xlwt.Alignment.VERT_CENTER # May be: VERT_TOP, VERT_CENTER, VERT_BOTTOM, VERT_JUSTIFIED, VERT_DISTRIBUTED

style = xlwt.XFStyle() # Create Style

style.alignment = alignment # Add Alignment to Style

worksheet.write(0, 0, 'Cell Contents', style)

workbook.save('Excel_Workbook.xls')

Adding Borders to a Cell

# Please note: While I was able to find these constants within the source code, on my system (using LibreOffice,) I was only presented with a solid line, varying from thin to thick; no dotted or dashed lines.

import xlwt

workbook = xlwt.Workbook()

worksheet = workbook.add_sheet('My Sheet')

borders = xlwt.Borders() # Create Borders

borders.left = xlwt.Borders.DASHED # 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.

borders.right = xlwt.Borders.DASHED

borders.top = xlwt.Borders.DASHED

borders.bottom = xlwt.Borders.DASHED

borders.left_colour = 0x40

borders.right_colour = 0x40

borders.top_colour = 0x40

borders.bottom_colour = 0x40

style = xlwt.XFStyle() # Create Style

style.borders = borders # Add Borders to Style

worksheet.write(0, 0, 'Cell Contents', style)

workbook.save('Excel_Workbook.xls')

Setting the Background Color of a Cell

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')

TODO: Things Left to Document

- Panes -- separate views which are always in view

- Border Colors (documented above, but not taking effect as it should)

- Border Widths (document above, but not working as expected)

- Protection

- Row Styles

- Zoom / Manification

- WS Props?
