これは、この質問に対する Google のトップの結果なので、より良い解決策を投稿すると思いました。私の答えはここから直接来ます
doc テンプレートを使用している場合は、特定のテーブル セルに縦書きのテキストを作成する非常に軽量な Flowable を使用できます。
# rotatedtext.py
from reportlab.platypus.flowables import Flowable
class verticalText(Flowable):
'''Rotates a text in a table cell.'''
def __init__(self, text):
Flowable.__init__(self)
self.text = text
def draw(self):
canvas = self.canv
canvas.rotate(90)
fs = canvas._fontsize
canvas.translate(1, -fs/1.2) # canvas._leading?
canvas.drawString(0, 0, self.text)
def wrap(self, aW, aH):
canv = self.canv
fn, fs = canv._fontname, canv._fontsize
return canv._leading, 1 + canv.stringWidth(self.text, fn, fs)
次に、ドキュメントで使用するには:
# vertical_text_table.py
from reportlab.pdfbase import pdfmetrics
from reportlab.pdfbase.ttfonts import TTFont
from reportlab.lib import colors
from reportlab.lib.colors import HexColor
from reportlab.lib.pagesizes import letter
from reportlab.lib.styles import getSampleStyleSheet
from reportlab.lib.units import inch
from reportlab.platypus import (
BaseDocTemplate, Frame, Paragraph, NextPageTemplate,
PageBreak, PageTemplate, Image, Table, TableStyle, Spacer)
from rotatedtext import verticalText
document = BaseDocTemplate(
'Vertical.pdf')
Elements = []
titleFrame_1 = Frame(
0.5*inch, 0.75*inch, 7*inch, 9*inch, id='col1', showBoundary=0)
titleTemplate_1 = PageTemplate(
id='OneCol', frames=titleFrame_1)
document.addPageTemplates([titleTemplate_1])
cw = [1.2*inch] + [1*inch]*6
rh = [0.25*inch] + [.6*inch] + [0.25*inch]*7
data = [
['Some', 'Reporting', '', 'Data', '', 'Here', ''],
['', verticalText('Vertical'), verticalText('Text'),
verticalText('Vertical'), verticalText('Text'),
verticalText('Vertical'), verticalText('Text')],
['Row1', '0', '0', '69', '803', '20751', '11627'],
['Row2', '0', '0', '1', '0', '1096', '103'],
['Row3', '0', '0', '0', '0', '233', '1'],
['Row4', '0', '0', '0', '0', '694', '38'],
['Row5', '0', '0', '23', '2', '1319', '2'],
['Row6', '0', '0', '0', '0', '0', '0'],
['TOTAL', '0', '0', '93', '805', '24093', '11771'],
]
ts = [
('GRID', (0, 0), (-1, -1), 0.5, colors.black),
('SPAN', (1, 0), (2, 0)),
('SPAN', (3, 0), (4, 0)),
('SPAN', (5, 0), (6, 0)),
('SPAN', (0, 0), (0, 1)),
('ALIGN', (0, 0), (-1, 1), 'CENTER'),
('ALIGN', (0, 2), (-1, -1), 'RIGHT'),
('VALIGN', (0, 0), (-1, -2), 'MIDDLE'),
('FONT', (0, 0), (-1, 1), 'Helvetica-Bold', 7, 7),
('FONT', (0, 2), (0, -2), 'Helvetica-Bold', 7, 7),
('FONT', (1, 2), (-1, -2), 'Helvetica', 7, 7),
('FONT', (0, -1), (-1, -1), 'Helvetica-Bold', 8, 8),
('TEXTCOLOR', (0, -1), (-1, -1), colors.white),
('BACKGROUND', (0, -1), (-1, -1), colors.black),
]
t = Table(
data, style=ts,
colWidths=cw, rowHeights=rh)
Elements.append(t)
document.build(Elements)
これにより、次のことが得られます。
