I try to enclose treetable into my library, but there comes a problem about how to 

invoke each function in treetable individually. 

The main code snippet is as following:

2.  $.fn.treetable = function(method) {
3.     if (methods[method]) {
4.       return methods[method].apply(this, Array.prototype.slice.call(arguments, 1));
5.     } else if (typeof method === 'object' || !method) {
6.       return methods.init.apply(this, arguments);
7.     } else {
8.       return $.error("Method " + method + " does not exist on jQuery.treetable");
9.     }
10.   };

And the main problems is it using methods[method] to map the options to individual function, 

but if I hope to use its all function in my library via the same way, it will be duplicated and 

verbose. Something like that:

2. $.fn.myownfunction=function(options)
3. {
4.    this.treetable(options)
5. }

Seems useful, but It means I can not add my own options in initial step. Otherwise, I need to do the same things like  

2. $.fn.myownfunction=function(method)
3. {
4.    if (methods[method]) {
5.       return methods[method].apply(this, Array.prototype.slice.call(arguments, 1));
6.     } else if (typeof method === 'object' || !method) {
7.       return methods.init.apply(this, arguments);
8.     } else {
9.       return $.error("Method " + method + " does not exist on jQuery.myownfunction");
10.     }
11. }
12. 
    
13.  methods = {
14.    init:function(options, force){
15.    ....
16.    ......
17.    this.treetable(options, force);
18.    } 
19.    otherfunction:
20.    .....   
21.    ..............
22.  }

A work around, but not effectively.   Is there any other good way to fix the subject? thanks a lot
