这个表格写了很久了，最近才整理。
自定义表格可以根据数据自动生成表头，多级表头，列
约定的数据格式如下：

/** 数据格式
   *
   headList:[
   {
     prop:"date",
     label:"日期",
     width:"150",
     url:'',
     path:'',
     yl:'',
     children:[]
   },
   {
     prop:"",
     label:"地址",
     width:"",
     url:'',
     path:'',
     yl:'',
     children:[{
       prop:"province",
       label:"省份",
       width:"120",
       url:'',
       path:'',
       yl:'',
     },
       {
         prop:"zip",
         label:"邮编",
         width:"120",
         url:'',
         path:'',
         yl:'',
       }
     ]
   }
   ],
   tableData: [{

        province: '上海',
        city: '普陀区',
        address: '上海市普陀区金沙江路 1518 弄',
