The `datatable-datalet` is a porting of Datatables JQuery library in a web component that has built up by using Polymer.
Pass to this component a data url(CKAN api uri) and a string with one or multiple query in JsonPath format(separated by spaces) and it'll show a
table with data and query attributes with all Datatables library features.
Example:
<datatable-datalet
data-url="http://ckan.routetopa.eu/api/action/datastore_search?resource_id=#"
fields='["field1","field2"]'>
</datatables-datalet>
@element datatable-datalet
@status v0.1
@demo demo/index.html
@group datalets
