如何通过reportlab将表格放置在特定的x和y坐标处

Question

我有以下代码可生成pdf：

def colr(x, y, z):
    return (x/255, y/255, z/255)
import reportlab
from reportlab.lib.pagesizes import A4
from reportlab.pdfgen.canvas import Canvas
from reportlab.lib.utils import ImageReader
from reportlab.platypus import SimpleDocTemplate, TableStyle, Paragraph, Image, Spacer, Frame, Paragraph
from reportlab.platypus.tables import Table
from reportlab.lib import colors
from reportlab.lib.styles import getSampleStyleSheet, ParagraphStyle
from reportlab.lib.enums import TA_JUSTIFY, TA_LEFT, TA_CENTER
styles = getSampleStyleSheet()
styleN = styles["BodyText"]
styleN.alignment = TA_LEFT
width, height = A4
logo = '/home/joel/myappointments/appointments/static/clinic/img/logo/logo.png'
elements = []
print(f'Height={height}')
imgw = imgh = 100
im = Image(logo, width=imgw, height=imgh)
im.hAlign = 'LEFT'
elements.append(im)

headstyle = ParagraphStyle(
    name='MyHeader',
    fontName='Helvetica-Bold',
    fontSize=16,
    leading =10
)
doctorstyle = ParagraphStyle(
    name='MyDoctorHeader',
    fontName='Helvetica',
    fontSize=13,
    leading =10
)
data = [[Paragraph("Dr John Doe's ENT Clinic", style = headstyle)], [Paragraph("Dr John Doe", style = doctorstyle)], [Paragraph("ENT Specialist", style = doctorstyle)], [Paragraph("Registration No. ", style = doctorstyle)]]
elements.append(Table(data, repeatRows=1))
line1 = ("Name", "Test", "Age", "20yr")
line2 = ("MRD No.", "18","Date", "14-11-2018")
line3 = ("No.","#", "Doctor", "Dr.John Doe")
data=[line1,line2, line3]
patientdetailstable = Table(data)
patientdetailstable.setStyle(TableStyle([
    ('BACKGROUND', (0, 0), (4, 0), '#CFEAD4'),
    ('BACKGROUND', (0, 2), (4, 2), '#CFEAD4'),
    ('BOX',(0,0),(-1,-1), 0.5, '#CFEAD4'),
    ('GRID',(0,0),(-1,-1), 0.5, colr(12, 43, 8)),
]))
elements.append(patientdetailstable)
elements.append(Spacer(1, 20))
# We use paragraph style because we need to wrap text. We cant directly wrap cells otherwise
line1 = ["Sl.", "Medicine" , "Dose", "Freq", "Durn", "Note"]
drug1 = Paragraph('AUGMED Syrup 30ml (AMOXICILLIN 200MG + CLAVULANATE(CLAVULANIC ACID) 28.5MG)', styleN)
line2 = ["1", drug1, "1 Tab", "1-0-1", "5 days", ""]
line3 = ["2", drug1, "1 Tab", "1-0-1", "5 days", ""]
data=[line1,line2, line3]
for i in range(3,50):
    temp = [str(i), "Some Drug here", "5 ml", "1-0-1", "10 days", "No comments"]
    data.append(temp)

medstable = Table(data, repeatRows=1)
medstable.setStyle(TableStyle([
    ('VALIGN',(0,0),(-1,-1), 'TOP'),
    ('TEXTCOLOR',(0,0),(-1,0),colors.white),
    ('BACKGROUND', (0, 0), (-1, 0), colr(40, 196, 15)),
    ('GRID',(0,1),(-1,-1), 0.5, '#CFEAD4'),
                            ]))
elements.append(medstable)
doc = SimpleDocTemplate('output.pdf', pagesize=A4, rightMargin=20, leftMargin=20, \
    topMargin=20, bottomMargin=20, allowSplitting=1,\
    title="Prescription", author="MyOPIP.com")
doc.build(elements)

一切正常，除了我需要在徽标的右侧而不是其下方的区域John Doe's ENT clinic到Registration No为止。如果我直接使用Canvas而不是使用可流动的SimpleDocTemplate，则可以轻松设置其位置。

使用SimpleDocTemplate，如何任意放置该节？

Answer 1

我找到了一个解决方案，它可能不是最优雅的解决方案。摆弄框架和其他可流动对象之后，我重新阅读了文档，发现我可以将我的表封装在另一个表中以进行格式化。因此，我创建了一个一行，两列的表，并将图像插入到一列，另一表插入了第二列。
