reportlab 设置左表位置

Question

如何设置表格的左侧位置？

response = HttpResponse(mimetype='application/pdf')
response['Content-Disposition'] = 'attachment; filename=%s' % pdf_name
buffer = StringIO()
PAGESIZE = pagesizes.portrait(pagesizes.A4)
doc = SimpleDocTemplate(buffer, pagesize=PAGESIZE, leftMargin=1*cm)
story = []

story.append(Paragraph(header_part2, styleN))
table_row = ['Total Score:','']
data.append(table_row)
ts = [
    #header style    
    ('LINEABOVE', (0,0), (-1,0), 1, colors.gray),
    ('LINEBELOW', (0,0), (-1,0), 1, colors.gray)]
t = Table(data, (6*cm,6*cm), None, style=ts)
    story.append(t)
    doc.build(story)
    pdf = buffer.getvalue()
buffer.close()
response.write(pdf)

段落打印时距左侧一厘米，而表格打印时与左页面边框几乎没有距离。

我必须在哪里设置表格位置的 leftMargin？

这同样适用于我添加的图像。它们似乎印在某处。

story.append(Image(path,35,10))

找到了神奇的 hAlign 关键字:

t = Table(data, (6*cm,6*cm,2*cm,2*cm,2*cm), None, style=ts, hAlign='LEFT')
