Django 在Reportlab中，表的数据格式是什么

在报告中，我尝试添加行和列，但遇到错误

/billing/invoce_report/'int'对象处的TypeError不可编辑

我认为问题在于，

reportlab.platypus.Table

对象的数据参数需要是一个列表列表，而不是一个简单的列表。该嵌套列表是一个二维数据网格，即与表相同的结构。第7.1章“表格方法”对此进行了说明

# So this will work:
data = [
    [1,2,3],
    [4,5,6],
    [7,8,9],
]

# as will a single row:
data = [ [1,2,3] ]

# but a simple list with numbers in it will not work (your current data):
data = [1,2,3]

# however, a list of strings appears to work - like table headings?
data = ['testing', '1', '2']

是的，这是真的。这个问题的解决方案是什么？请在产品数据周围多加一对括号：

product\u data=[[…]]

。或者，我看到你说你想要消息中的行和列，所以如果你想要多行，那么就把数据像网格一样排序。但仍然面临错误。就像我在问题中提到的，看看产品数据和pdf数据。请在这里写一些代码，以便我能轻松理解

# So this will work:
data = [
    [1,2,3],
    [4,5,6],
    [7,8,9],
]

# as will a single row:
data = [ [1,2,3] ]

# but a simple list with numbers in it will not work (your current data):
data = [1,2,3]

# however, a list of strings appears to work - like table headings?
data = ['testing', '1', '2']
