错误看起来像是您试图格式化表格,如果框架在单个页面中,则超出了限制。我用“Table”和“LongTable”测试了一段代码,只要您不试图同时格式化第一页和第二页,它就会在多个页面上显示数据
示例代码:
#!/usr/bin/env python
# -*- coding: utf-8 -*-
from reportlab.platypus import SimpleDocTemplate, Table, LongTable, TableStyle, BaseDocTemplate, Frame, Paragraph, NextPageTemplate, PageTemplate
from reportlab.lib.pagesizes import letter, inch
from reportlab.lib import colors
def testPdf():
doc = BaseDocTemplate("testpdf.pdf",pagesize=letter,
rightMargin=72,leftMargin=72,
topMargin=72,bottomMargin=18, showBoundary=True)
width, height = letter
print width
print height
elements = []
datas = []
for x in range(1,50):
datas.append(
[x,x+1]
)
t=LongTable(datas)
tTableStyle=[
('INNERGRID', (0,0), (-1,-1), 0.25, colors.black),
('BOX', (0,0), (-1,-1), 0.25, colors.black),
]
t.setStyle(TableStyle(tTableStyle))
elements.append(t)
frameT = Frame(doc.leftMargin, doc.bottomMargin, doc.width, doc.height, id='normal')
doc.addPageTemplates([PageTemplate(id='OneCol',frames=frameT)])
doc.build(elements)
if __name__ == '__main__':
testPdf()
如果您将表格格式化为:
tTableStyle=[
('SPAN',(0,0),(0,38), #span over the frame limit
('INNERGRID', (0,0), (-1,-1), 0.25, colors.black),
('BOX', (0,0), (-1,-1), 0.25, colors.black),
]
那么您将遇到此错误。我想说最好的方法可能是手动格式化表格,但我希望有更好的解决方案
