How do I connect a table in JQuery?

[elll]

I have this code:

$(document).ready(function() {

$("#pn_deactivatepositionnumber").autocomplete({

source: ,

minLength:0

}).bind('focus', function(){ $(this).autocomplete("search"); } );

});

I am trying to get data from a power portal table to create suggestions as a user types in a form field, but I don't know how to add the table as the source. Does anyone know what I should put?
