The KingTable widget offers two ways to override base functions:

• define a new type of KingTable, using its extend function
• pass a second parameter inside the constructor: it will be used to extend the instance

The KingTable adopts the extend function of Backbone library. This example shows how to use the extend function, to define a custom type of KingTable:

var SpecificTable = $.KingTable.extend({
  
  mixinAjaxPostData: function () {
    //overrides the base mixinAjaxPostData
  }

});

//create an instance of SpecificTable:
var instance = new SpecificTable({
  //options that would normally used
  url: "/api/some/url",
  $el: $("#container")
});

//render
instance.render();

The strength point of this approach, is that it makes possible to define reusable types.

This example shows how to override base functions, by using the constructor:

var instance = new $.KingTable({
  //options as first parameter
}, {
  //the second parameter is used to extend directly the instance, even overriding base functions
  mixinAjaxPostData: function () {
    //overrides the base mixinAjaxPostData
  }
});

The strength point of this approach, is that it is faster; and of course doesn't override the base definition of the KingTable prototype.
