<h:form id="tableForm">
   <table id="myTable">
     <tr>
       <th>HeaderOne</th>  
       <th>HeaderTwo</th>
       <th>HeaderThree</th>
     </tr>
     <ui:repeat value="#{myBean.List}" var="row">
       <tr class="myRows">
         <td><input type="text" value="#{row.fieldOne} required="required" /></td>
         <td><input type="text" value="#{row.fieldTwo}  /></td>
         <td><input type="text" value="#{row.fieldThree} /></td>
       </tr>
     </ui:repeat>
   </table>
   <p:commandButton id="myButton" value="Load" action="#{myBean.load}" process="@this" update="myTable" />
</h:form>
<h:form id="tableForm">
   <table id="myTable">
