[reportlab-users] Re: Tablestyle.add() tuple unpack problem

[James StCyr]

Disclaimer:  I'm also slogging up the ReportLab learning curve.

Disclaimer aside, I think the problem is in the syntax of the 'add' 
method.  You have:

tblstyle.add([('BACKGROUND', (0,0), (-1,0), colors.Color(0,0.7,0.7))])

When you use TableStyle you're creating a list of tuples.  When you 
execute the above statement, you're putting a list within a list.  
That's fine syntactically with Python but causing an error with 
Reportlab. 

Try this:

tblstyle.add('BACKGROUND', (0,0), (-1,0), colors.Color(0,0.7,0.7))

The ReportLab supplied example test_platypus_tables.py has helped me 
out.
