当附件从后台请求，(即已有数据)，
重新渲染table的方法:

var active = {
            setAttachmentListView:function(_attachmentList){
                $.each(_attachmentList,function (index,item) {
                    var tr = $(['<tr id="upload-'+ index +'">'
                        ,'<td><a href="#" style="color:#1E9FFF" id="img_open_'+index+'" data-url="'+item+'">附件'+ (index+1) +'</a></td>'
                        ,'<td>已上传</td>'
                        ,'<td>'
                        ,'<button class="layui-btn layui-btn-mini layui-btn-danger test-upload-demo-delete">删除</button>'
                        ,'</td>'
                        ,'</tr>'].join(''));

                    //单个重传
                    tr.find('.test-upload-demo-reload').on('click', function(){
                        obj.upload(index, file);
                    });
                    tr.find("a#img_open_"+index).on('click',function () {
                        var url = $(this).attr("data-url");
                        if(url){
                            window.open(url);
                        }
                    })

                    //删除
                    tr.find('.test-upload-demo-delete').on('click', function(){
                        tr.remove();
                        attachmentList.splice(index,1);
                        uploadListIns.config.elem.next()[0].value = ''; //清空 input file 值，以免删除后出现同名文件不可选
                    });

                    attachmentListView.append(tr);
                });
            },
            
            
        };
