Applying borders to a cell in OpenPyxl

Question

I am trying to use Openpyxl to apply a border to a cell, but I have failed on the most basic \"apply any kind of border to any cell anywhere\" task. I tried copying from th

Answer 1

With openpyxl version 2.2.5, this snippet works for me:

from openpyxl.styles.borders import Border, Side
from openpyxl import Workbook

thin_border = Border(left=Side(style='thin'), 
                     right=Side(style='thin'), 
                     top=Side(style='thin'), 
                     bottom=Side(style='thin'))

wb = Workbook()
ws = wb.get_active_sheet()
# property cell.border should be used instead of cell.style.border
ws.cell(row=3, column=2).border = thin_border
wb.save('border_test.xlsx')

The documentation mentions other values for the style attribute :

Value must be one of {‘double’, ‘dashed’, ‘thin’, ‘medium’, ‘mediumDashDot’, ‘dashDot’, ‘thick’, ‘mediumDashed’, ‘hair’, ‘dotted’, ‘slantDashDot’, ‘mediumDashDotDot’, ‘dashDotDot’}

Answer 2

This answer works with version 2.4.8 The difference with the previous two answers is that the property for Side is border_style, not style

from openpyxl.styles.borders import Border, Side, BORDER_THIN
thin_border = Border(
    left=Side(border_style=BORDER_THIN, color='00000000'),
    right=Side(border_style=BORDER_THIN, color='00000000'),
    top=Side(border_style=BORDER_THIN, color='00000000'),
    bottom=Side(border_style=BORDER_THIN, color='00000000')
)
ws.cell(row=3, column=2).border = thin_border

Answer 3

With openpyxl version 2.0.4, this snippet works for me:

from openpyxl.styles.borders import Border, Side
from openpyxl.styles import Style
from openpyxl import Workbook

thin_border = Border(left=Side(style='thin'), 
                     right=Side(style='thin'), 
                     top=Side(style='thin'), 
                     bottom=Side(style='thin'))
my_style = Style(border=thin_border)

wb = Workbook()
ws = wb.get_active_sheet()
ws.cell(row=3, column=2).style = my_style
wb.save('border_test.xlsx')
