Layout of pdf file.

Layout of pdf file.

Hello everybody,
I have problem to display a table with many columns in a pdf file. It work fine when the number of the columns is about 15, but not when the number of the columns is > 15. It should automatically create a new page and it
should start from the next column from where it was interrupted.
I you like to see the execution, please:

Thanks in advance.
