This is the first time I've used ReportLab, I have tried to edit an existing script that does exactly what I want to do, but I get the following error, when I try and run the script.

Script -

parts.append(p)#Build document

The error that I get is:

Traceback (most recent call last):File "C:\Python25\Lib\site-packages\Pythonwin\pywin\framework\scriptutils.py", line 325, in RunScriptexec codeObject in __main__.__dict__File "H:\Report_v2.py", line 100, in <module>t=Table(data, colWidths=(100,100))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

Any ideas what I need to do as I am struggling a bit.

Thanks.

From the error and the code, the problem appears to be that data is an empty array []. ReportLab seems to choke on this, so you just need to actually supply some data to the table t and it should work.
