我想在python中用reportlab生成pdf報告。Python Reportlab分頁符
我的目標是讓我的pdf文件的第一頁只有一個簡單的標題和一個沒有實際內容的表格。實際內容將從第二頁開始。
通過查看一些SO帖子後,我發現可以使用afterPage()
命令來中斷頁面。所以,我想出了這樣的事情:
from reportlab.platypus import SimpleDocTemplate, Paragraph, Spacer,KeepTogether,tables
from reportlab.lib import colors
from reportlab.lib.styles import getSampleStyleSheet
from reportlab.rl_config import defaultPageSize
from reportlab.lib.pagesizes import A4,landscape
from reportlab.lib.units import inch,cm,mm
from reportlab.pdfgen import canvas
PAGE_HEIGHT = defaultPageSize[1]
PAGE_WIDTH = defaultPageSize[0]
styles = getSampleStyleSheet()
style = styles["Normal"]
def myFirstPage(canvas, doc):
canvas.saveState()
canvas.setFont('Times-Bold',15)
canvas.drawCentredString(PAGE_WIDTH/2.0, PAGE_HEIGHT-38, 'Title 1')
canvas.drawCentredString(PAGE_WIDTH/2.0, PAGE_HEIGHT-58, 'Title 2')
NormalStyle = tables.TableStyle([
('BOX',(0,0),(-1,-1),0.45,colors.blue),
('ALIGN',(0,0),(-1,-1),'LEFT'),
('BACKGROUND',(0,0),(-1,-1),colors.lightblue)
])
mytable = tables.Table([('test','test'),('test2','test2'),('test3','test3')],
colWidths = 1* inch,rowHeights= 0.25 *inch,style = NormalStyle)
mytable.wrapOn(canvas,PAGE_WIDTH ,PAGE_HEIGHT)
mytable.drawOn(canvas,(doc.width/2)-20,700)
doc.afterPage()
canvas.restoreState()
def myLaterPages(canvas, doc):
canvas.saveState()
canvas.setFont('Times-Roman', 9)
canvas.restoreState()
doc = SimpleDocTemplate("myreport.pdf",
leftMargin = 0.75*inch,
rightMargin = 0.75*inch,
topMargin = 1*inch,
bottomMargin = 1*inch)
data = "".join(['this is a test' for i in range(200)])
mydata = Paragraph(data,style)
Story = [Spacer(2.5,0.75*inch)]
Story.append(mydata)
doc.build(Story, onFirstPage=myFirstPage, onLaterPages=myLaterPages)
但不是所有的標題,表格和內容在第一頁繪製和afterPage()
功能不似乎對我的文檔的內容有任何實際效果。
如何更改我的代碼以使內容(我的代碼中的data
)從第二頁開始?
