Thank you for your quick responses and fixes. I know I am asking a lot, but
can I have one more request.
I can print JTable using latest version of iText, but now I having problems
printing the inner components within a JTable. It seems the inner
components are always printed on top of its container. For example if my
JTable have a JTree as its first column, the first column will overlaps the
second column when I print the table into a pdf, regardless how I set the
column width. This problem can be demostrated using the swing TreeTable
example, with the following code replacing the main. Is there are a way to
enforce the column width?
Also, I notice the file size of the resulting pdf is large. In my case, it
is > 500K. Is this expected?
I guess I have more than one request. Thanks again for your time and
efforts.
