connect datatable to table Joomla

ItalPascal

My operating system is OS Yosemite, I have to create the database with utility TableTools? How can I connect to a table of Joomla? Where do I put this code:

$ (document) .ready (function () {
$ ('# myTable'). DataTable ();
});

Thanks for your cooperation
Sorry for my English translated by Google;)

Se qualcuno risponde in italiano sarei molto contento, grazie
