No, t:dataTable and t:columns is the right approach.
However, you probably need to bind both UIData components to your backing
bean and call getRowData() on both to determine what to do.
You can take a look at this ancient piece of code I wrote a couple of years
ago that populates an nXm grid of checkboxes:
http://issues.apache.org/jira/secure/attachment/12311217/RowAndColumnRelationshipComponent.zip
Not everything in here is probably relevent to your situation (I was trying
to write a custom component that handled the entire grid by compositing a
bunch of components together in java code).
However, the backing model should show you what you need to do.
It's also possible that there's a far easier way to do what you're tying to
do.
If you're just trying to wrap an arbitrary number of elements, look into
using the newspaperColumn attributes to turn an nX1 list of data into a
nXconstant matrix of data.
You might also look at the t:schedule component since it sounds like you're
really trying to do some kind of calendar work :-)

Ok, it sounds like dataTable might be the wrong tag for me.
I have Core JavaServer Faces, but I did not see how to do this.
I am basically trying to draw an NxM grid where the grid elements are
custom elements.
I tried panelGrid, but unless I misunderstand it can not take in a value
or list to iterate over.
So I tried to use a dataTable, and I was trying to access the nxm element.
That was why I was trying to bind the integer index, because I could not
find another way to get the nxm th element.
I can display my own object if I can get it bound in the right place.
So if in the display of the panel grid, I had a "item" that was bound to
my object when displaying I could do what I wanted.
So lets say that I have an object Person which has a name field.
So this is what I would want to do
<h:panelGrid columns="7" value="${pgb.personBinding}" var="p">
<h:outputText value="#{p.name}"/>
</h:panelGrid>
To display
harrypetertomsallykathybarbara
Does that make sense?
It sounds like from this discussion that I am doing the wrong thing.
So what am I missing
Thanks
