如何去思考一个JQ的组件封装？想请教一个比较详细的思路，我自身在思考的时候对于这个学习没有一个太理想的思路。主要是在JS的代码结构规划上面。

比如：我有一个表格，里面放进了数量，名字，高度，宽度，等等一系列的数据，数据格式object,array,number,fn()等等各种都有。在外面调用这个组件时根据传入的数据将对应的信息显示出来。

这是一个别人封装的插件样例：

(function($ , undefined) {

    var Table = function (element, options) {
        this.$this = $(element);
        this.options = $.extend({}, $.fn.table.defaults, options);
        this.init();
    };
    // 使用proptotype给Table添加属性，
    Table.prototype = {
        constructor: Table,

        dataToObj: function(str){
            if(typeof str == "string" && str[0] == "&"){
                str = str.substring(1, str.length); 
            }
        
            if(typeof str == "string"){
                str = str.replace(/&/g,"','");
                str = str.replace(/=/g,"':'");
                str = "({'"+str +"'})";
                return eval(str); 
            }
        },

        init: function () {
            var options = this.options;
            if(!options.columns) return false;
            this.$this.html("");
            this.initTableHead();
            this.initTableBody(options.currentPage);
        },

        initTableHead: function(){
            var options = this.options,
                tableWrap = this.$this,
                attributesArr = [],
                theadStr = '<thead><tr class="'+options.hdBg+'">';

            for(var i=0, len=options.columns.length; i< len; i++){
                theadStr += '<th data-attribute="'+options.columns[i].dataIndex+'" width="'+(options.columns[i].width || "")+'">'+options.columns[i].title+'</th>';
                attributesArr.push(options.columns[i].dataIndex);
            }
            this.options.attributes = attributesArr;
            theadStr += '</tr></thead><tbody></tbody>';
            this.$this.append(theadStr);
        },

        initTableBody: function(currentPage){
            var that = this, options = this.options, data = null;
