      <div class="pagination-container">

data 中定义的变量
    data: function() {
    			return {
                       currentPage:1, //初始页
                    pagesize:10,    //    每页的数据　
                    total:0,
                    indexResultsTable:[],
                      
                }
    },
    // js 方法
    	methods: {
                 handleSizeChange:function(size){
                    this.pagesize = size;
                    this.getResultsTable();
                },
                   handleCurrentChange:function(page){
                    this.currentPage = page;
                    this.getResultsTable();
                },
                    //前端自己分页
                  getResultsTable:function() {
                    // es6过滤得到满足搜索条件的展示数据list
                    var self=this;
                    var list = self.accordionDataTwo.tableData;//后端回来表格的数据
                      //表格渲染的数据  indexResultsTable:[],
                    this.indexResultsTable = list.filter((item, index) =>
                        index < self.currentPage * self.pagesize && index >= self.pagesize * (self.currentPage - 1)
                    ) ;//根据页数显示相应的内容
                    this.total = list.length;
