如何在ReportLab中创建项目符号列表 [英] How to create a bulleted list in ReportLab

问题描述

如何在ReportLab中创建项目符号列表?该文档令人沮丧地含糊.我正在尝试:

How can I create a bulleted list in ReportLab? The documentation is frustratingly vague. I am trying:

text = ur '''
<para bulletText="&bull;">
item 1
</para>
<para bulletText="&bull;">
item 2
</para>
'''
Story.append(Paragraph(text,TEXT_STYLE))

但是我不断收到类似list index out of range的错误.看来我一次调用Paragraph()不能放多个<para></para>吗?我也尝试设置TEXT_STYLE.bulletText="•"，但这也不起作用...

But I keep getting errors like list index out of range. It seems that I can't put more than one <para></para> in a single call to Paragraph()? I also tried setting TEXT_STYLE.bulletText="•" but that doesn't work either...

推荐答案

bulletText参数实际上是Paragraph对象的构造函数，而不是<para>标记:-)尝试以下操作:

The bulletText argument is actually a constructor to the Paragraph object, not the <para> tag :-) Try this:

story.append(Paragraph(text, TEXT_STYLE, bulletText='-'))

请参阅 ReportLab文档. ReportLab中的约定似乎是使用<bullet>标记，并且文档确实警告您每个Paragraph实例只能有一个.我们像这样在ReportLab中渲染项目符号:

Have a look at the examples on page 68 (page 74 now, in 2012) of the ReportLab Documentation, though. The convention in ReportLab seems to be to use the <bullet> tag, and the docs do warn that you can have only one per Paragraph instance. We render our bullets in ReportLab like so:

story.append(Paragraph('<bullet>The rain in spain</bullet>', TEXT_STYLE))
