问题 I am trying to layout a table in reportLab in the following format. The table is dynamic and can have many rows. --------- | a | b | |---| | | a | | |---| | | a | | --------- tTableStyle=[ ('SPAN',(1,0),(1,-1)) ] Works beautifully if the table fits on one page but crashes if the table is split over pages. Without the span the table splits ok but I'm stuck with the gridlines in the second column. Have read here that this is due to the algorithm used not being able to SPAN across pages

问题 What is an efficient way to generate PDF for data frames in Pandas? 回答1: Well one way is to use markdown. You can use df.to_html() . This converts the dataframe into a html table. From there you can put the generated html into a markdown file (.md) (see http://daringfireball.net/projects/markdown/basics). From there, there are utilities to convert markdown into a pdf (https://www.npmjs.com/package/markdown-pdf). One all-in-one tool for this method is to use Atom text editor (https://atom.io/)

问题 Okay i created a script today that takes an item# or any number for that purpose to generate a barcode. Now i wanted to print 60 same barcodes in 4 columns, that would make it a matrix of (15 X 4) only making it easy to understand. Now i successfully achieved it with a custom sized page (900*850) and fitted in 15 rows and 4 columns of barcodes generated by reportlab code128. Here is the code: from reportlab.graphics.barcode import code128 from reportlab.lib.units import mm from reportlab

问题 I try for weeks to create pdf reports in Arabic, but I failed. I use ReportLab with two packages for building the Arabic characters namely bidi.algorithm and arabic_reshaper. In the console the characters are well organized but in the pdf there are only black square. import reshaper from bidi.algorithm import get_display heading = get_display(reshaper.reshape(unicode('العربية', encoding='utf-8'))) print heading The output in console : العربية But in the generated pdf file : ▀ ▀ ▀ ▀ ▀ Thank

问题 Is it possible to generate a PDF file using ReportLab in such a way that the front page (and possibly table of contents) are excluded from the page numbering done by Platypus? 回答1: Yes. The first example on chapter 5 of the user guide, SimpleDocTemplate has two hooks: doc.build(Story, onFirstPage=myFirstPage, onLaterPages=myLaterPages) Just change myLaterPages definition to conditionally print the page number. 来源： https://stackoverflow.com/questions/4956283/non-numbered-pages-in-reportlab

问题 this is a bit related to this post I am trying to place an image on the background, and I want to be able to write text over it. using canvas.drawImage helps, but that's too low level approach for me. My program uses platypus, but canvas.drawImage is part of different library. I've been able to insert images with platypus.Image , but couldn't figure out how to make it as background. Any advice would be great, Thanks D 回答1: When you create a page template in Platypus you have the ability to
