Hi,
I'm using MyFaces from SVN head, and JSP to generate HTML.
I need to be able to set the width for various columns on the table, and
adding styles to each cell isn't sufficient - I need the COL tag
functionality.
As far as I can see, none of the table components available can generate
COL html elements. Is this correct?
I'm working on a patch to add this functionality. It involves
modifications to HtmlTableRenderer, called just after <TABLE> has been
emitted. My current code iterates over all child UIColumn components of
the HtmlDataTable:
* if child has a facet named "colstyle":
* emit a <COL span="n"> to match any preceding UIColumn that
didn't have this facet
* get the first child of that component and render it.
This then allows:
<t:dataTable>
<t:column>...</t:column>
<t:column>...</t:column>
<t:column>
<f:facet name="header">
...
</f:facet>
<f:facet name="colstyle">
<t:colstyle style="color:green" width="0*"/>
</f:facet>
<h:outputText value="test"/>
</t:column>
</t:dataTable>
to generate
<TABLE>
<COL span="2">
<COL style="color:green" width="0*">
<THEAD>
<TR><TH>...</TH></TR>
<TBODY>
....
</TABLE>
There is something slightly odd about this use of facets though. In
other cases, facets are used to hold arbitrary components that are
rendered. Here, I'm really assuming the facet holds a component that
generates a COL tag; anything else will result in a malformed page.
Can anyone suggest an alternative way for columns to specify their COL
data? Storing these attributes directly on the t:column tag isn't really
practical I think.
NB: I'll also handle UIColumns (ie t:columns) children but didn't want
to confuse things further here...
Cheers,
Simon
