我正在创建一个 PDF，其中包含一个表格，但表格行在 PDF 和 PDF 之间会有所不同

    table = Table(data, colWidths=[3.05 * cm, 4.5 * cm, 4 * cm,3* cm, 3 * cm])
    table.setStyle(TableStyle([
                   ('INNERGRID', (0,0), (-1,-1), 0.25, black),
                   ('BOX', (0,0), (-1,-1), 0.25, black),
                   ]))
    table.wrapOn(self.pdf, self.width_table, self.height_table)
    table.drawOn(self.pdf, *self.coord(1.0, 18.6,cm))

这就是我现在用来创建表格的东西。

谢谢，

对于任何刚开始的人来说，这都是一个核心问题。

以下是开始构建的完整可行代码。答案是，正如您在评论中自己写的那样，是循环。但是，以后任何人都会发现的问题是您如何处理多页表和这些表的设计。有各种值得研究的解决方案。

from reportlab.lib import colors
from reportlab.platypus import Frame, PageTemplate, KeepInFrame
from reportlab.lib.units import cm
from reportlab.platypus import (Table, TableStyle, BaseDocTemplate)
