为Reportlab中的每列设置不同的大小

from reportlab.lib.pagesizes import letter
from reportlab.platypus import SimpleDocTemplate, Table, TableStyle

# 创建一个包含数据的二维列表
data = [
    ['Name', 'Age', 'Gender'],
    ['John Doe', '30', 'Male'],
    ['Jane Smith', '25', 'Female'],
    ['Bob Johnson', '40', 'Male']
]

# 创建一个PDF文档
doc = SimpleDocTemplate("table.pdf", pagesize=letter)

# 创建一个表格，并设置表格样式
table = Table(data)
table.setStyle(TableStyle([
    ('BACKGROUND', (0, 0), (-1, 0), 'gray'),
    ('TEXTCOLOR', (0, 0), (-1, 0), 'white'),
    ('ALIGN', (0, 0), (-1, -1), 'CENTER'),
    ('FONTNAME', (0, 0), (-1, 0), 'Helvetica-Bold'),
    ('FONTSIZE', (0, 0), (-1, 0), 12),

]))

# 设置每列的宽度
tablestyle = TableStyle([('COLWIDTHS', (0, 0), (-1, -1), [100, 50, 75])])
table.setStyle(tablestyle)

# 将表格添加到文档中并保存
doc.build([table])
