dataTable possible: combine some members in a row?

[javatwo]

For example, a list of 3 elements A, B, and C.  I like dataTable to output the list in the following layout:

A in 1st row,

B and C in 2nd row, 2 columns.

---------------

      A

--------------

B    |     C

--------------

Is this possible for rich:dataTable?

Thanks for help.

Hi Dave,

Yes, this is possible. Please take a look at livedemo example.

Hi Nick,

Thanks for reply.  I looked at the live demo. I did not see the example of showing data (rows) in one row as the layout above.

data list = { A, B, C}.

layout:

----------

A

-----------

B | C

-----------

Thanks for help.

check colspan, rowspan and breakBefore usage.

To my knowledge, colspan, rowspan and breakBefore are for columns of one row, and they can not be used across data list. If you could show me how to use it, it would be great help.

Thanks,

Got it.. and seems you're right.

So the first to try is to wrap for example this objects as properties of some parent single object and create list of the wrapper objects and use:

<dataTable value="#{list}" var="var">
     <column colspan="2">
          <outputText value="#{var.propertyA}">
     </column>
     <column breakBefore="true">
          <outputText value="#{var.propertyB}">
     </column>
     <column>
          <outputText value="#{var.propertyC}">
     </column>
<dataTable>

And the other way is to define B and C as some child sublist of A and the use subtable for them. So A will be master table row and B and C in details table.

Thanks for your ideas. They will work, I believe. There might be an issue for ajax.

For example, ajax reRender an Component(id="Foo") in C. 

Normally I can use ajaxKeys={2}.

For method 1, ajaxKeys={0},  all the Foo(s) in A, B and C have to be reRendered.

For method 2 (with subTable), how to use ajaxKeys to render Foo in C?

Thanks,

Dave

Hi Dave,

You can set "ajaxKeys" for subtable.
