Re: dynamic table in report

Hi all,

I want to display a table in a pdf-file. The problem is that the
number of rows is dynamic. Furthermore the rows form thematic
clusters. As an example:

cluster A
subcluster A.1
data 1
data 2
data 3
..
subcluster A.2
data i
data i+1
...
cluster B
subcluster B.1
data j
data j+1
..

The number of rows in each subcluster is dynamicand I want to have a
page breaks after a subcluster. That means, if a subcluster does not
fit on the currrent page, the whole subcaption-cluster should be on
the next page. It is not necessary that each cluster is on the same
page, only subcluster. I used for each row a fo:block element and set
the keep-with-previous attribute to handle it and it works.

But if
there are to many rows in a subcluster, there will be a page overflow,
which makes sense. But how can I handle this? If the number of rows in
a subcluster is too big, there should be automatically a page break.

Many of my students are surprised that XSL-FO
allows many <table-body> constructs within a
single <table> and your use-case is an ideal
situation in which to take advantage of this.

Simply put each sub-cluster into a separate
<table-body> and use
keep-together.within-column="always" on that body
segment.  No other keeps are needed.

I am using Apache FOP 0.95.

I have no idea if the example below works in
FOP.  It works with three other XSL-FO tools I've tested it with this
morning.
