setFont在ReportLab中，Django

Question

我想爲我的pdf文件在reportLab中設置西里爾字體。我發現一些關於它的文章，例如：

pdfmetrics.registerFont(TTFont('VeraBI', 'VeraBI.ttf')) 

canvas.setFont('Vera', 32) 

但問題是我不使用畫布。我發現這個視圖創建一個表格，並且它不使用canvas。如何設置我的字體？ `

    from reportlab.platypus import SimpleDocTemplate, Table, TableStyle, Paragraph 
    from reportlab.lib.styles import getSampleStyleSheet 
    from reportlab.pdfbase import pdfmetrics 
    from reportlab.pdfbase.ttfonts import TTFont 
    pdfmetrics.registerFont(TTFont('Arimo-Regular', 'static/themes/font/Arimo-Regular.ttf'))

    response['Content-Disposition'] = 'attachment; filename="somefilename.pdf"' 
    buff = StringIO() 
    menu_pdf = SimpleDocTemplate(buff, pagesize=A4, rightMargin=30,leftMargin=30, topMargin=30,bottomMargin=18)

          ('BOX', (0,0), (-1,-1), 0.25, colors.black), 
          ]) 
    #Configure style and word wrap 
    s = getSampleStyleSheet() 
    s = s["BodyText"] 
    s.wordWrap = 'CJK' 
    data2 = [[Paragraph(cell, s) for cell in row] for row in data] 
    t = Table(data2) 
    t.setStyle(style) 


    #Send the data and build the file 
    elements.append(t) 
    menu_pdf.build(elements) 
    response.write(buff.getvalue()) 
    buff.close() 
    return response

可以通過創建自己的風格並在任何地方使用嗎？如實施例：

styles = getSampleStyleSheet() 
    styles.add(ParagraphStyle(name='Justify', alignment=TA_JUSTIFY, fontName='Times', fontSize=10)) 
    styles.add(ParagraphStyle(name='Justify-Bold', alignment=TA_JUSTIFY, fontName='Times-Bold')) 
    bold_style = styles['Justify-Bold'] 
    normal_style = styles['Justify'] 

或：

doc_title = copy.copy(styles["Heading1"]) 
    doc_title.alignment = TA_CENTER 
    doc_title.fontName = 'Times-Bold' 
    doc_title.fontSize = 16
