Andreas,
Thank you for such a comprehensive reply. I will certainly look at the
work being done for QGIS 3.0 and see if I am able to support it.
Thanks
Martin

Hi Martin,
Unfortunately, what you want, is not possible currently. The only
thing you can do is to place the dynamic elements (e.g. attribute
table) last in your layout and let it flow over several pages. All the
static stuff needs to be placed first.
For QGIS 3.0, Nyall Dawson, will do a rewrite/redesign of the QGIS
print composer. There will be an additional "reporting mode" to allow
such things you want to do (page flow, place items relative to other
items, etc.). See his website for more details:
http://north-road.com/qgis-layout-and-reporting-engine-campaign/ - he
will update it soon, after the release of QGIS 2.16. If you are
interested in such functionality, and have some financial resources,
we would very much welcome if you could join this crowd-funding
effort, once, more information will be available. Caveat: you will
have to wait until the 3.x releases, which will be in Feb/March 2017
at the earliest (no gurarantees).
Until then, your only chance to get something similar is to put
everything in a dynamic HTML code and let it flow over multiple pages.
QGIS 2.16 comes with an improvement to allow working with table
relations. This change makes the current atlas feature (and
additionally all attributes of related child features) available to
the source of a composer HTML item, allowing the item to dynamically
adjust its rendered HTML in response to the feature's properties. An
example use case is dynamically populating a HTML table with all the
attributes of related child features for the atlas feature. To use
this, the HTML source must implement a "setFeature(feature)"
JavaScript function. This function is called whenever the atlas
feature changes, and is passed the atlas feature (and all related
attributes) as a GeoJSON Feature.
Sorry that I don't have better news - but at least the issue is known,
devs are aware of it and will propose solutions for QGIS 3.0.

Richard,
Thank you for your thoughts. Unfortunately the approach you suggest
would not allow the tables to move up or down the page as objects are
added or deleted from the maps in a dynamic way. I could add x and y
fields for each attribute table to my Atlas control layer but I would
need to update them every time new records were added. My document
has 50 pages of maps so I was hoping for a solution that would use
the position and size overides you describe but in a dynamic way.
Thanks

Martin,
You can specify the position and size of the table?tables using
attributes, you could set up an x and y column on your tables which
you could use the *Data defined Overide* options to set your
location this is under *Attribute Table, Item Options, Position and
Size *on the composer.
Might be a solution for you!
Regards,
Richard.

Hi,
I am producing a multi page document using the atlas function in
print composer. I have pairs of pages with a map on the left side
and 4 attribute tables on the facing page showing details of 4
different objects on the map. For each pair of pages there are a
variable number of objects shown of each type. Each object is fetch
from its own postgis table as the fields stored for each object is
different.
At the moment I have the attribute tables defined to handle the
largest number of items found on the map but this means, on some
pages, there are large gaps before the next table starts. Would it
be possible to have a variable exported from an attribute table
that could be used to position the next table a suitable distance
apart?
Thanks for the help
Martin
