[reportlab-users] RE: Table Height

[Henning von Bargen]

It is not clear what you want to achieve:

Do you mean you want to repeat the footer on each page
of the table or do you want to see the footer only on the last page?

As you probably know, repeating the header on each page
is no problem, just use the repeatRows argument in the Table =
constructor.

If the footer should print only on the last page, there's no problem.
If you really want the footer on every page of the table, it becomes
difficult.

I think you would have to subclass the Table class
and implement the footer row yourself.
Basically this means changing the _splitRows function.
Look for the block following if repeatRows: ,
you would have to do something similar for the footer, I once =
implemented
something like this for a test.

BTW what information would you print in the footer?
Something like a running total? This could be tricky perhaps.

What you are trying right now is dividing the long table into many =
small
tables,
is that correct? I guess that's why you are trying to determine the =
height
yourself.

It seems the wrong direction for me, because it contradicts the ideas =
of
platypus.

If you're splitting the table into many small ones just for performance
reasons,
you should also try my LongTable class (I can send it to you if you =
like).
It works the same as Table, but performs much better for long tables.

Another option you can think about is to put the header and footer =
portions
into your page templates.
