js/jq动态创建表格的行与列

之前做了一个项目，需求是能动态创建表格行，动态创建表格的列，度了很多资料，都没有动态创建列的插件，所以自己动手写了一个

需求大概是（下图）

1.动态添加一行、2.动态添加一列，3.删除行、4.删除列，5.复制行，6.表头的选项是可自定义写入，7.表格的数据可后台传入，也可写入，8.提交数据到后台

//html文件（首先写在html文件中写好表格结构代码，后面再把注释掉的html压缩写到js文件中进行插件的封装）

<div class="creta-table"></div>

	<!--<div class="table">
        <ul class="tbody">
