OpenPyXL library-cell style settings
The control of the cell depends on the openpyxl.style package, which defines the required objects and introduces related:
from openpyxl.styles import PatternFill, Font, Alignment, Border, SideBorder Side Border PatternFill Fill Font Font Aignment Alignment
The above can basically meet the needs
The basic usage is to assign the set properties of the cell object to a new corresponding object that is different from the default.
Import excel
from openpyxl import load_workbook
from openpyxl.styles import Border,Side
wb = load_workbook("template.xlsx")#Use openpyxl to read xlsx files and create workbook
ws = wb.active
ws
<Worksheet "sheet1">
1. Border Side border
from openpyxl.styles import Border, Side
border_type=Side(border_style=None, color='FF000000')
border = Border(left=border_type,
right=border_type,
top=border_type,
bottom=border_type,
diagonal=border_type,
diagonal_direction=0,
outline=border_type,
vertical=border_type,
horizontal=border_type
)
The border_style are:
‘dashDot',‘dashDotDot',‘dashed',‘dotted',‘double', ‘hair',‘medium',‘mediumDashDot',‘mediumDashDotDot', ‘mediumDashed',‘slantDashDot',‘thick',‘thin'
For example, the original excel
# 1-Narrow border, black
thin = Side(border_style="thin", color="000000")#边框，
border = Border(left=thin, right=thin, top=thin, bottom=thin)#The position of the border
ws['A3'].border = border #A3 cell set border
for row in ws['A5:D6']:
for cell in row:
cell.border = border#A5:D6 area cell set border
wb.save("test.xlsx")
effect:
# 2- wide border, blue
thin = Side(border_style="thick", color="0000FF")#边框
border = Border(left=thin, right=thin, top=thin, bottom=thin)#The position of the border
ws['A3'].border = border #A3 cell set border
for row in ws['A5:D6']:
for cell in row:
cell.border = border#A5:D6 area cell set border
wb.save("test.xlsx")
effect:
2. Font settings
from openpyxl.styles import Font
font = Font(name='Calibri',
size=11,
color='FF000000',
bold=False,
italic=False,
vertAlign=None,
underline='none',
strike=False)
Font name, font size, font color, bold, italic, vertical alignment (there are three: baseline, superscript, subscript), underline, strikethrough, font color can be RGB or aRGB,
font = Font(size=14, bold=True, name='Microsoft Yahei', color="FF0000")#font size, bold, font name, font name
ws['A3']="Welcome to pay attention: Eternal King's Treasure Box"
ws['A3'].font = font
wb.save("test.xlsx")
3. Fill
from openpyxl.styles import PatternFill
# fill_type is None or solid
fill = PatternFill(fill_type = None,start_color='FFFFFF',end_color='000000')
fill_type type
有：'none'、'solid'、'darkDown'、'darkGray'、'darkGrid'、'darkHorizontal'、'darkTrellis'、'darkUp'、'darkVertical'、'gray0625'、 'gray125'、'lightDown'、'lightGray'、'lightGrid'、'lightHorizontal'、 'lightTrellis'、'lightUp'、'lightVertical'、'mediumGray'
The official document states that if fill_type does not specify the type, the subsequent parameters are invalid
So the above code will have a problem, start_color represents the foreground color, end_color is the background color, the reason for setting two parameters is to facilitate the filling and the display of the gradient color (personally think)
If you want to fill with a solid color, you can use'solid', and then make the foreground color what you need, namely:
fill = PatternFill(fill_type = None,start_color='FF0000')
fill = PatternFill(patternType="solid", start_color="33CCFF")#Pure color fill
ws['A3']="Welcome to pay attention: Eternal King's Treasure Box"
ws['A3'].fill = fill
wb.save("test.xlsx")
4. Align
from openpyxl.styles import Alignment
align = Alignment(horizontal='left',vertical='center',wrap_text=True)
Horizontal represents the horizontal direction, can be left aligned, there are center center and right aligned right, distributed alignment, center continuous across columns, justify justify, fill, regular general
vertical stands for the vertical direction, it can be centered, top, bottom, justify, and distributed
Automatic wrapping: wrap_text, this is a boolean parameter, this parameter can also be written as wrapText
align = Alignment(horizontal='right',vertical='center',wrap_text=True)#Pure color filling
ws['A3']="Eternal King's Treasure Box"
ws['A3'].alignment = align
wb.save("test.xlsx")
