Introduce a tag e:columns
-------------------------

                 Key: JBSEAM-4392
                 URL: https://jira.jboss.org/jira/browse/JBSEAM-4392
             Project: Seam
          Issue Type: Feature Request
          Components: Excel
            Reporter: Marcos Ribes


If you have a unknow number of columns, theres no way to create a excel using jboss-excel. A solution is create a tag e:columns like a existent rich:columns.

Here's an example of what I'd like to do: 
<e:workbook>
  <e:worksheet name="cars">
    <e:columns  value="#{dataTableScrollerBean.columns}" var="columns"
                index="ind">
      <f:facet name="header">
        <e:cell value="#{columns.header}"/>
      </f:facet>
      <e:cell value="#{model[ind].model}"/>
    </e:columns>
  </e:worksheet>
<e:workbook>
