这是我的问题的一个例子。

from reportlab.lib import colors
from reportlab.platypus import SimpleDocTemplate, Table
doc = SimpleDocTemplate("test.pdf")
element = []
data = [["Testing Table", ""], ["Short content", "This is a short content."],["Long content", "aaaaaaaaaaaaa This is a super long content which I dont know how to
automaticaly make it fit my A4 page. aaaaaaaaaaaaaaaaaaaa"]]
t = Table(data, style=[("BOX", (0, 1), (-1, -1), 2, colors.black),
("GRID", (0, 1), (-1, -1), 0.5, colors.black),
("ALIGN", (0, 0), (0, -1), "CENTER"),
("VALIGN", (0, 0), (-1, -1), "MIDDLE"),
("ALIGN", (1, 1), (1, -1), "LEFT")])
element.append(t)

我不确定reportlab中是否提供了选项，但您可以使用textwrap模块在外部执行此操作。
输入数据：
data = [["Testing Table", ""],
["Short content", "This is a short content."],
["Long content", "aaaaaaaaaaaaa This is a super long content which I dont know how to automaticaly make it fit my A4 page.aaaaaaaaaaaaaaaaaaaa"]]处理中：
data = [(header, '\n'.join(textwrap.wrap(content, width=70))) for header, content in data]textwrap.wrap会拆分超过70个字符的行。join使用换行符(\n)将它们相加在一起。
这将导致输出格式：

您可以将长文本(或所有文本)包装在一个Paragraph对象中。
为了避免重复使用Pragraph("...", style)，我创建了一个函数P(txt)。
from reportlab.lib import colors
from reportlab.platypus import SimpleDocTemplate, Table, Paragraph
from reportlab.lib.styles import getSampleStyleSheet
doc = SimpleDocTemplate("test.pdf")
element = []
style = getSampleStyleSheet()['Normal']
def P(txt):
return Paragraph(txt, style)
data = [[P("Testing Table"), ""], [P("Short content"), P("This is a short content.")],
[P("Long content"), P("aaaaaaaaaaaaa This is a super long content which I dont know how to automaticaly make it fit my A4 page. aaaaaaaaaaaaaaaaaaaa")]]
t = Table(data, style=[("BOX", (0, 1), (-1, -1), 2, colors.black),
("GRID", (0, 1), (-1, -1), 0.5, colors.black),
("ALIGN", (0, 0), (0, -1), "CENTER"),
("VALIGN", (0, 0), (-1, -1), "MIDDLE"),
("ALIGN", (1, 1), (1, -1), "LEFT")])
element.append(t)
doc.build(element)输出：
