Table Modifiers
 
  One of the main uses for a custom runner was to add functionality to AutoTables.  
 
  The 
 vdl-table tag, which is the VDL 
 4.1 version of the VDL 2.0 autotable tag, has a 
 modifier attribute which accepts a single function reference as an expression. 
 
 
<script>
        function modifierFunc(config) {
                // do something with config object as needed
                return config;
        }
</script>
<vdl-table modifier="=modifierFunc"></vdl-table> 
The modifier function is called with the existing AutoTable config and it is required to alter this config and return it for further customization of the AutoTable.
