19.2. Creating a simple workbook

The worksheet support is used like a <h:dataTable>, and can be bound to a List, Set, Map, Array or DataModel.
 
<e:workbook xmlns:e="http://jboss.com/products/seam/excel"> 
  <e:worksheet> 
    <e:cell column="0" row="0" value="Hello world!"/> 
  </e:worksheet> 
</e:workbook>
The following is a more common use case:
 
<e:workbook xmlns:e="http://jboss.com/products/seam/excel"> 
  <e:worksheet value="#{data}" var="item"> 
    <e:column> 
      <e:cell value="#{item.value}"/> 
    </e:column> 
  </e:worksheet> 
</e:workbook>
The top-level workbook element serves as the container, and has no attributes. The child element, worksheet, has two attributes: value="#{data}" is the EL-binding to the data, and var="item" is the name of the current item. The worksheet contains a single column. Within this is the cell, which is the final bind to the data in the currently iterated item.
Now you can bind your data into spreadsheets.
