Either keeps in table rows in 0.20.5 or non-collapsing paragraphs in .90alpha
Hi, all,
I'm creating reports for a new client. The reports consist entirely of
tables (not blind tables used for layout but actual tabular content).
In 0.20.5, I can't get keep-together or keep-with-next to work on a table
row. I get page breaks within table-cells.
In .90alpha, I don't get page breaks in table-cells, but it causes another
problem. .90alpha collapses (renders with 0 height, it seems) blocks that
contain just a non-breaking space (that is, character & # 1 6 0 ; with extra
spaces). I need those blocks to be full height, as I am using them to
position things within table cells. Collapsing <fo:block/> would be fine
(I'm using empty blocks for page breaks between tables, in fact, and it's
good there), but it seems to me that blocks with content (even just a space)
shouldn't be collapsed.
So, I either need to know how to get page breaks to not occur within table
cells (that is, only at the rows between cells) in 0.20.5 or I need to know
how to prevent blocks that contain spaces from collapsing in .90alpha. The
0.20.5 solution would be preferred, but I think I can talk my client into
moving to .90alpha if it fixes the page break problem.
Thanks

Yes. keep-together worked in 0.90. Specifically, I used
<fo:table-row keep-together.within-page="always">

I lurk on the dev list, so I've been seeing your discussion of the beta. I
look forward to it, as it will make it easier to talk my clients into using
0.90. They are justifiably leary of anything called "alpha". Of course,
they'll still be leary of a beta release, too, but less so.

Ah, I see you have multiple lines in a table-cell. In that case, just
specify "5em" (the number of lines you have in "em") on
block-progression-dimension.minimum.

That didn't work with 0.90. Here's a snippet from what I tested:
<fo:table-row block-progression-dimension.minimum="1em"
keep-together.within-page="always">
<fo:table-cell border-width="1pt" border-style="solid"
border-color="black">
<fo:block xsl:use-attribute-sets="headerleft"><xsl:value-of
select="@name"/></fo:block>
<fo:block xsl:use-attribute-sets="headerleft"><xsl:value-of
select="@city"/></fo:block>
<fo:block xsl:use-attribute-sets="headerleft"><xsl:value-of
select="@address"/></fo:block>
</fo:table-cell>
<fo:table-cell border-width="1pt" border-style="solid"
border-color="black">
<fo:block/>
<fo:block/>
<fo:block/>
<fo:block/>
<fo:block xsl:use-attribute-sets="headercenter"><xsl:value-of
select="@id"/></fo:block>
</fo:table-cell>
0.90 collapses those empty blocks.

I'm not so much into 0.20.5 these days, so without a demo file to start
from (to save time) I can only try to help you with 0.90. We do have
some problems with collapsing nbsps as you might have seen on this list
lately. What I think could work for you is to specify
block-progression-dimension.minimum="1em" on a table-row. In that case,
a row cannot collapse even if you only use a minimum <fo:block/> inside
the table-cells. Did I understand you correctly that keep-together on
the table-rows works for you as expected in 0.90? HTH
BTW, we're planning on releasing a beta version in the next few days,
hopefully this week since I want to take a week off.

It feels like a hack, too. I'll try your ideas.

Well, while I was preparing a sample that would show the problem, I got
keep-together="always" to work the way it should. I'm not sure what changed,
so I'll let the matter drop, as I don't have time to pursue much testing at
present.
Thanks.

That seems like a hack. Please try my suggestions I just sent.

keep-together is supposed to work if specified on a table-row. Does that
mean that this doesn't work in your case. If you can post a small
example, I can have a look.

I used block-containers with height attribute values wrapped around empty
blocks to make my spacer blocks, so I've gotten the .90alpha solution to
work. Combined with the -q option to shut off all the to-do messages, it'll
work.
I'd still like to know how to prevent page breaks within table cells in
0.20.5 in case my client (or some future client) resists going to .90alpha.
Thanks some more.
