Here is a code sample. Uncomment the static NUM_FILLER_ROWS at the top
of the class to see the different cases. Also, notice my bookmark for
case 3 seems wrong. It looks like getVerticalPosition is returning the
Y of page 1 where the table _would_ have been added if it could fit,
instead of the end of the table on page 2.
I need to create a table that has 2 "parts" (let's call them A and B).
"A" is a number of rows up to and including the first transaction on the
account (there may be 0 or more transactions). "B" is the remaining
transactions. So for example:
(A*)|SAVINGS ACCOUNT 12345 |
(A) |SAVINGS ACCOUNT SUMMARY|
(A*)|COLUMN HEADERS |
(A) |BEGINNING BALANCE |
(A) |FIRST TRANSACTION |
(B) |TRAN 2 |
(B) |TRAN 3 |
(B) |TRAN N |
(B) |ENDING BALANCE |
The business rules are:
1) all rows "A" have to appear on the same page
2) a bookmark (destination) needs to be created so users can "jump"
straight to "A"
3) TRAN rows should have an alternating background
4) if rows from "B" span multiple pages, rows A* should be printed as
headers rows
I've tried to build this a few different ways and haven't been totally
successful. My best attempt was to use two tables (A and B). Table A
is setKeepTogether(true) with no header rows and setSpaceAfter(0).
Table B has two header rows, setKeepTogether(false), and
skipFirstHeader(true). The issue is when Table A takes you to the very
bottom of the current page, when you add Table B, it can't add the first
row, so it's forwarded to the next page, and the header is still
skipped.
I guess what I really want is a way to say "skip first header if added
to current page" concept.
Can you provide some guidance on how to accomplish this? Is there a way
to modify header rows on the fly in an on page start/end event?
Does this even make sense.
