HOW TO USE IT IN WCM :
1/ import it in your template :
<script type="text/javascript" src="/eXoStaticResources/table.js"></script>

2/ add the following in your template (dialog or view)
DIALOG EXAMPLE
<tr>                        
  <td colspan="2">
    <%
      String[] fieldDescription = ["jcrPath=/node/exo:description"] ;
      uicomponent.addTextField("description", fieldDescription) ;
    %>
    <div id="wcmtable"></div>
  </td>
  <script type="text/javascript">
    // new UITable ( array of cols, number of rows, div id for inputs, input id where to load/save data )
    eXo.ecm.UITable = new UITable(["Title", "Description"], 3, "wcmtable", "description");
    eXo.ecm.UITable.setTypes(["TEXT", "TEXTAREA"]);
    eXo.ecm.UITable.enableNewLine(); 
    eXo.ecm.UITable.generateInputs();
  </script>
</tr>
      
VIEW EXAMPLE
<div class="summary" >
<%if(node.hasProperty("exo:description")) {%>
  <div id="desctable"></div>
  <script type="text/javascript">
    // new UITable ( array of cols, number of rows, div id for output)
    eXo.ecm.UITable = new UITable(["Title", "Description"], 3, "desctable");
    eXo.ecm.UITable.setJson(<%=node.getProperty("exo:description").getString()%>);
    eXo.ecm.UITable.generateTable();
    //alert(eXo.ecm.UITable.getValue(1, 1));
  </script>
<%}%>
</div>
