Re: image in table header overlapping table body <-- possible ? [additional info]

[Roland Schroth <rs...@albit.de>]

I think your idea could work if i had only one table starting at the top of
the page.

   But (sorry that i did not mention that) i have a sequence of tables of
   different lengths that therefore also may start in the middle of a page.
   There are tables being only a few rows long an others spanning 2 or 3
   pages. So i need something that will work for that case too.

Anyway, thanks for your quick response.

Ooops ... no sorry. One of these situations, my lack of practice with the
english language shows up.

    I  *absolutely need*  it to be repeated.

Thanks again,

Aaah... you *don't* need the image repeated across pages.

So, the image would actually belong to the table-body, and only the text
belongs to table-header (? correct?).
In that case my proposal could work, if it were not for the complication
described below.

Very dirty indeed... Imagine having to deal with a situation like this and
having to base your calculations on the metrics of the particular font being
used. (for fixed-width fonts this would be a bit less complicated since you
can just take the number of chars and multiply that by the charwidth).

Very wise indeed!

Cheerz,

So put a single cell in the body beneath the image.
Put a blank image or a non-breaking space( ) in it to force it to appear.

That is what i tried yesterday, too. Thanks anyway.
It's a solution to get the image in the first header of the table. But i
still end up with the problem having it repeated after a page break.
The text header will be repeated as there is data in its table-body being
continued after the page break. But there is no data in the table-body that
belongs to the image header so there is no reason for FOP to repeat the
header (the image) on the next page.
And with this problem in mind i come to the idea of Andreas.

And here we have my next problem ...
There occur line breaks in the rows (mostly generated within FOP caused by
hyphenation), that i cannot calculate that easy. Therefore i cannot set a
fixed row height and i do not know how many rows there will be on a page. I
tried to calculate these linebreaks according to the amount of text in the
fields but that's quite dirty (and not completely functioning at all ...)

I agree.

I think i will try to get some other things working first and come back to
this one next week. Sometimes a weekend of doing nothing helps more than
days of thinking ;-)

Thanks to both of you and have a nice weekend,
Roland

The mistake was mine... Didn't study the drawing closely enough to see that
it was about *table* headers. Sorry 'bout that.

A very tough one...

I see a remote possiblity in performing some XSL trickery (resting on the
assumption that the rows in the table body are generated by XML elements).
If you define a row height globally in your stylesheet, as well as the
region-body height... You know in advance how many rows will fit on a
page... ( $regbh div $rowh ).
Then, for each set of XML elements (corresponding to a table) you know in
advance how many rows will be generated (counting the nodes). You also know
that the first element of the set/table will generate an additional row to
accomodate the header-text & the image --first cell has a rowspan of 4 - so
if a table starts at the top of the page, you will be able to put ( ( $regbh
div $rowh ) - 1 ) of the XML elements (rows) on the same page.
If the table starts in the middle of a page and each table is being
generated by a template, maybe the maximum possible number of rows that can
still fit on the 'page' can be passed in as a parameter...
(Keep in mind that this is all pure calculation, as there is no concept of a
page-layout at the XSLT stage.)

Then again... having to keep count of the elements and inserting a 'fake'
header at every expected page-break is hardly an ideal situation. (Not to
mention that it will lead to trouble if somehow the page-break doesn't end
up where expected)

For the moment, however, it's the closest thing to a solution I can come up
with...

Anyone?


Cheerz,

Andreas
