ReportLab - 테이블을 만들 때 오류가 발생했습니다.

Question

ReportLab을 처음 사용한 것은 기존의 스크립트를 편집하려고 시도했지만 시도하고 실행할 때 다음 오류가 발생합니다. 스크립트.

스크립트 -

I가 얻을 오류 :

Traceback (most recent call last): 
    File "C:\Python25\Lib\site-packages\Pythonwin\pywin\framework\scriptutils.py", line 325, in RunScript 
    exec codeObject in __main__.__dict__

    File "C:\Python25\Lib\site-packages\reportlab\platypus\tables.py", line 236, in __init__ 
    raise ValueError("%s must have at least a row and column" % self.identity()) 
ValueError: <Table@0x010F4710 0 rows x unknown cols>... must have at least a row and column 

내가 조금 고군분투으로 내가해야 할 일을 어떤 아이디어가.

감사합니다.

오류 및 코드에서 data이 빈 배열 [] 인 것 같습니다. ReportLab은 이것에 대해 질식하는 것처럼 보이기 때문에 테이블 t에 실제로 일부 데이터를 제공하면됩니다.
