如何使用Reportlab鸭嘴兽（对齐段落）

Question

我尝试使用reportlab和Playtipus模块从python创建PDF。在

我希望pdf看起来像这样：

问题是我不知道如何处理布局。 我创建了一个简单的页面模板，它是主页，有一个简单的框架 但在这个简单的框架内，我需要一个流动的“两个科隆”布局。在

页面模板：

class PageOne(PageTemplate):

def __init__(self, context):
    self.context = context
    self.largeur = self.context.doc.pagesize[0]
    self.hauteur = self.context.doc.pagesize[1]

    self.simpleFrame = Frame(self.context.doc.leftMargin, self.context.doc.bottomMargin, self.context.doc.width, self.context.doc.height - 3*cm, id='normal');
    PageTemplate.__init__(self, id="PageOne", frames=[self.simpleFrame], pagesize = A4, onPage = CommonReportPdf.footer_and_header)
    print("here 1 ")   

def beforeDrawPage(self, canvas, doc):
    canvas.saveState()
    try:
        print("beforeDrawPage")
    finally:
        canvas.restoreState()

自定义截面模型（表示具有关联测试的零件）：

^{pr2}$

流动性：

class SectionItemWithValue(Flowable):

    def __init__(self, title, result, value, x=0, y=-15, width=80, height=15):
        self.title = title
        self.result = result
        self.value = value

    def draw(self):
        self.canv.saveState()
        try:
            print("ok")
        finally:
            self.canv.restoreState()

class SectionItemWithoutValue(Flowable):

    def __init__(self, title, result, x=0, y=-15, width=80, height=15):
        self.title = title
        self.result = result

    def draw(self):
        self.canv.saveState()
        try:
            print("ok")
        finally:
            self.canv.restoreState()

Pdf生成类：

class XmlToPdf:

def __init__(self, xml_file):

    #self.root_xml = self.init_xml(xml_file)
    destination_path = "XmlToPdf.pdf"
    self.elements = []
    self.doc = BaseDocTemplate(destination_path, showBoundary=0, leftMargin=0.7 * cm, rightMargin=0.7*cm, topMargin=0.7*cm, bottomMargin=0.7*cm, pagesize=A4)
    self.simpleFrame = Frame(self.doc.leftMargin, self.doc.bottomMargin, self.doc.width, self.doc.height - 5*cm, id='normal')

def init_xml(self, xml_file):
    tree = ET.parse(xml_file)
    return tree.getroot()  

def create_pdf(self):
    styles = getSampleStyleSheet()

    _baseFontNameBI = tt2ps(_baseFontName, 1, 1)

    styles.add(ParagraphStyle(name='RightAlign', alignment=TA_RIGHT))
    styles.add(ParagraphStyle(name='LeftAlign', alignment=TA_LEFT))

    self.elements.append(Paragraph("Frame two columns,  "*2,styles['LeftAlign'])) #  I want both on the same line
    self.elements.append(Paragraph("Frame two columns,  "*2,styles['RightAlign'])) #  I want both on the same line
    self.elements.append(PageBreak())
    self.elements.append(Paragraph("Une colonne",styles['Normal']))
    self.elements.append(PageBreak())

    textWidth = stringWidth("Test title 1  ", _baseFontNameBI, 14)
    box = CustomSection(title="Contrôle logiciels", width=textWidth)
    self.elements.append(box)

    self.elements.append(Spacer(0, 20))

    self.elements.append(Paragraph("This is a paragraph", styles["Normal"]))

    textWidth = stringWidth("Test title 2", _baseFontNameBI, 14)        
    box = CustomSection(title="Test title 2", width=textWidth)
    self.elements.append(box)        
    self.elements.append(Spacer(0, 1*inch))

    textWidth = stringWidth("Test title 3", _baseFontNameBI, 14)
    box = CustomSection(title="Test title 3", width=textWidth)
    self.elements.append(box)        
    self.elements.append(Spacer(0, 1*inch))

    textWidth = stringWidth("Test title 4", _baseFontNameBI, 14)        
    box = CustomSection(title="Test title 5", width=textWidth)
    self.elements.append(box)        
    self.elements.append(Spacer(0, 1*inch))                        

    self.doc.totalPages = 4
    templates = [PageOne(self)]

    self.doc.addPageTemplates(templates)
    self.doc.build(self.elements)

我使用正确的组件吗？你有一些“复杂”的文档例子吗？如何处理版面和段落？我要用桌子吗？在
