Hello Bruno,
I would like to have a PDF document with all tables. And I used following line
code:
table.setTableFitsPage(true);
table.setOffset(28);
The first table of the first page takes an offset 28 from the top. But the
first tables of other( second, third ...) pages do not, instead the offset is
0.
For example: I have 5 tables in my PDF file, 4 tables are in first page and
the fifth is in second page, document.top() = 30, offset = 28. The first table
is 28 far from the top. But the fifth table is 0 far from the top. I would
like to have the fifth table is also 28 pixels far from the top.
I tried to use bottom() to solve the problem. But it did work as I expected.
Could you please help me with another better way?
Thank you very much for your time.
Regards,
Linhda
