如何使用ReportLab在PDF中定位表格？

from reportlab.pdfgen import canvas
from reportlab.lib.pagesizes import letter
from reportlab.lib import colors
from reportlab.platypus import Table, TableStyle

c = canvas.Canvas("example.pdf", pagesize=letter)

data = [
    ['姓名', '年龄', '性别'],
    ['张三', '25', '男'],
    ['李四', '30', '女'],
    ['王五', '27', '男']
]

style = TableStyle([
    ('BACKGROUND', (0, 0), (-1, 0), colors.grey),
    ('TEXTCOLOR', (0, 0), (-1, 0), colors.whitesmoke),
    ('ALIGN', (0, 0), (-1, -1), 'CENTER'),
    ('FONTNAME', (0, 0), (-1, 0), 'Helvetica-Bold'),
    ('FONTSIZE', (0, 0), (-1, 0), 14),
    ('BOTTOMPADDING', (0, 0), (-1, 0), 12),
    ('BACKGROUND', (0, 1), (-1, -1), colors.beige),
    ('GRID', (0, 0), (-1, -1), 1, colors.black),
])

table = Table(data)
table.setStyle(style)

table.wrapOn(c, 200, 400)
table.drawOn(c, 100, 500)

c.save()
