我使用ReportLab在PDF文檔中編寫表格,對結果非常滿意(儘管尚未完全掌握流動模型)。如何在ReportLab的PDF輸出中重複表格列標題頁面中的分頁符
但是,我一直無法弄清楚如何製作跨越分頁符的表格,並重複列標題。
下面的代碼在C:\ Temp中創建一個test.pdf,它有一個標題行,後跟99行數據。
標題行在第一頁看起來不錯,但我希望在第二頁和第三頁的頂部重複。
我很想聽聽使用SimpleDocTemplate完成該操作的任何方法。
from reportlab.platypus import SimpleDocTemplate, Table, TableStyle, Paragraph, Frame, Spacer
from reportlab.lib import colors
from reportlab.lib.units import cm
from reportlab.lib.pagesizes import A3, A4, landscape, portrait
from reportlab.lib.styles import ParagraphStyle, getSampleStyleSheet
from reportlab.lib.enums import TA_LEFT, TA_RIGHT, TA_CENTER, TA_JUSTIFY
from reportlab.pdfgen import canvas
pdfReportPages = "C:\\Temp\\test.pdf"
doc = SimpleDocTemplate(pdfReportPages, pagesize=A4)
# container for the "Flowable" objects
elements = []
styles=getSampleStyleSheet()
styleN = styles["Normal"]
# Make heading for each column
column1Heading = Paragraph("<para align=center>COLUMN ONE HEADING</para>",styles['Normal'])
column2Heading = Paragraph("<para align=center>COLUMN TWO HEADING</para>",styles['Normal'])
row_array = [column1Heading,column2Heading]
tableHeading = [row_array]
tH = Table(tableHeading, [6 * cm, 6 * cm]) # These are the column widths for the headings on the table
tH.hAlign = 'LEFT'
tblStyle = TableStyle([('TEXTCOLOR',(0,0),(-1,-1),colors.black),
('VALIGN',(0,0),(-1,-1),'TOP'),
('BOX',(0,0),(-1,-1),1,colors.black),
('BOX',(0,0),(0,-1),1,colors.black)])
tblStyle.add('BACKGROUND',(0,0),(-1,-1),colors.lightblue)
tH.setStyle(tblStyle)
elements.append(tH)
# Assemble rows of data for each column
for i in range(1,100):
column1Data = Paragraph("<para align=center> " + "Row " + str(i) + " Column 1 Data" + "</font> </para>",styles['Normal'])
column2Data = Paragraph("<para align=center> " + "Row " + str(i) + " Column 2 Data" + "</font> </para>",styles['Normal'])
row_array = [column1Data,column2Data]
tableRow = [row_array]
tR=Table(tableRow, [6 * cm, 6 * cm])
tR.hAlign = 'LEFT'
tR.setStyle(TableStyle([('BACKGROUND',(0,0),(-1,-1),colors.white),
('TEXTCOLOR',(0,0),(-1,-1),colors.black),
('VALIGN',(0,0),(-1,-1),'TOP'),
('BOX',(0,0),(-1,-1),1,colors.black),
('BOX',(0,0),(0,-1),1,colors.black)]))
elements.append(tR)
del tR
elements.append(Spacer(1, 0.3 * cm))
doc.build(elements)
感謝戈登 - 指點我回到了手動已經使我能夠開發一個更簡單和有效的代碼示例,我將在下面添加一個答案。 – PolyGeo 2012-02-15 04:16:25
