使用reportlab在一行中需要两个不同的对齐

from reportlab.lib.styles import getSampleStyleSheet, ParagraphStyle
from reportlab.platypus import Paragraph
from reportlab.lib.enums import TA_LEFT, TA_RIGHT

styles = getSampleStyleSheet()
left_align = ParagraphStyle(name='left_align', parent=styles['Normal'], alignment=TA_LEFT)
right_align = ParagraphStyle(name='right_align', parent=styles['Normal'], alignment=TA_RIGHT)

text1 = "Left aligned text"
text2 = "Right aligned text"

p1 = Paragraph(text1, left_align)
p2 = Paragraph(text2, right_align)

from reportlab.pdfgen import canvas

pdf = canvas.Canvas("example.pdf")
pdf.drawString(100, 700, p1)
pdf.drawString(200, 700, p2)
pdf.save()
