Anton Belevich updated RF-1870:
-------------------------------
Fix Version/s: 4.0.0.M1
(was: 4.0.0.ALPHA2)
not in A2 scope: need additional time to redesign our datatable/subtable
renderers to support 'layout' attribute.
> Need to allow for single set of headers with datatable and embedded datatable
> -----------------------------------------------------------------------------

> I have a need to present a datatable that models the information in a
> spreadsheet. As such, some of the columns are "scalars", which represent a
> single value per entity, and some of the columns are multi-valued, such that
> multiple row values correspond to a single entity.
> For instance, consider the notion of a "Project" entity with "name" and
> "department" fields, along with a "servers" list property. Each server has
> "hostname", "cpuCount", and "platform" fields. I want to display a table with
> a single list of column headers, being "name", "department", "host name",
> "cpu count", and "platform" (and some others).
> One row in the "projects" table will have an embedded table for servers.
> In current functionality in v3.1.2, I can have a single header in the main
> datatable that corresponds to the embedded datatable (like "Servers"), and I
> can have headers in the embedded datatable (which would repeat for every
> project row), but there appears to be no way to just have a single set of
> headers representing all the existing columns unioned from the main datatable
> and the embedded datatable.
> I've looked at the "subTable" component, but this doesn't appear to do what I
> need.
> I will attach some artifacts that demonstrate what I'm trying to achieve.
