I have asked for it some time ago, but I didn't get any satisfying
answer: how to make summary at end of the page using FOP? I want to
print long table on few pages, and on every page I want to put summary
under some columns (where should be sum of column values). The problem
is that I don't know where is the page break and which values I have to
sum.
As you've been told, use markers. Note that you can't tell
the formatter to sum up stuff, you'll have to put already
prepared markers into the FO source.
For "summing up the whole stuff until this point" this is
easy. Lets say your data is 10, 20, 30, ...
The prepare a FO like (pseudo code)
<fo:table-row>
<fo:table-cell>
<fo:block><fo:marker marker-class-name="sum">10</fo:marker>
10
</fo:block>
</fo:table-cell>
</fo:table-row>
<fo:table-row>
<fo:table-cell>
<fo:block><fo:marker marker-class-name="sum">30</fo:marker>
20
</fo:block>
</fo:table-cell>
</fo:table-row>
<fo:table-row>
<fo:table-cell>
<fo:block><fo:marker marker-class-name="sum">600</fo:marker>
30
</fo:block>
</fo:table-cell>
</fo:table-row>
and use something like
<fo:block>Sum: <fo:retrieve-marker retrieve-class-name="sum"
retrieve-position="last-starting-within-page"/></fo:block>
If you want to have sums per page, this is difficult to impossible
because you don't know where to start the summation.
