利用xlwt寫excel可以將單元格合併

1.寫入行列值

import xlwt
# 創建一個workbook 設置編碼
workbook = xlwt.Workbook(encoding='utf-8')
# 創建一個worksheet
worksheet = workbook.add_sheet('My Worksheet')

# 寫入excel
# 參數對應 行, 列, 值
worksheet.write(1, 0, label = 'this is test')

# 保存
workbook.save('Excel_test.xls')

            

2.更改樣式

import xlwt

workbook = xlwt.Workbook(encoding = 'ascii')
worksheet = workbook.add_sheet('My Worksheet')
style = xlwt.XFStyle() # 初始化樣式
font = xlwt.Font() # 爲樣式創建字體
font.name = 'Times New Roman'
font.bold = True # 黑體
font.underline = True # 下劃線
font.italic = True # 斜體字
style.font = font # 設定樣式
worksheet.write(0, 0, 'Unformatted value') # 不帶樣式的寫入

worksheet.write(1, 0, 'Formatted value', style) # 帶樣式的寫入

workbook.save('formatting.xls') # 保存文件

3.設置單元格寬度

import xlwt

workbook = xlwt.Workbook()
worksheet = workbook.add_sheet('My Sheet')
worksheet.write(0, 0,'My Cell Contents')

# 設置單元格寬度
worksheet.col(0).width = 5555
workbook.save('cell_width.xls')

4.輸入日期進表格

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')

5.合併行列單元格

import xlwt
workbook = xlwt.Workbook()
worksheet = workbook.add_sheet('My Sheet')
#　　　　　　　　　　　　　#  0 0 行　0 3 列
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
                    #  1 2 行　0 3 列
worksheet.write_merge(1, 2, 0, 3, 'Second Merge', style)
workbook.save('Excel_Workbook.xls')

６.設置單元格對齊方式

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)
worksheet.col(0).width = 5555
workbook.save('Excel_Workbook.xls')

7.爲單元格設置背景色

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')

8.爲單元格設置邊框

import xlwt

workbook = xlwt.Workbook()
worksheet = workbook.add_sheet('My Sheet')
borders = xlwt.Borders()  # Create Borders
borders.left = xlwt.Borders.DASHED
# DASHED虛線
# NO_LINE沒有
# THIN實線

# 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')
