请问我的django分页组件，在后端向前端传数据时，如果是列表套字典的形式就可以正常分页，我传一个二维数组的形式，分页组件就失灵了，求帮我看一下问题在哪

下面这是分页组件的代码，也是在网上学的

from django.utils.safestring import mark_safe
class Pagination(object):
    def __init__(self, request, queryset, page_size=15, page_param="page", plus=5):
        from django.http.request import QueryDict
        import copy
        query_dict = copy.deepcopy(request.GET)
        query_dict._mutable = True
        self.query_dict = query_dict
        self.page_param = page_param
        page = request.GET.get(page_param, "1")
        if page.isdecimal():
            page = int(page)
        else:
            page = 1
        self.page = page
        self.page_size = page_size
        self.start = (page - 1) * page_size
        self.end = page * page_size
        self.page_queryset = queryset[self.start:self.end]
        total_count = len(queryset)
        total_page_count, div = divmod(total_count, page_size)
        if div:
            total_page_count += 1
        self.total_page_count = total_page_count
        self.plus = plus
    def html(self):
        if self.total_page_count <= 2 * self.plus + 1:
            start_page = 1
            end_page = self.total_page_count
        else:
            if self.page <= self.plus:
                start_page = 1
                end_page = 2 * self.plus + 1
            else:
                if (self.page + self.plus) > self.total_page_count:
                    start_page = self.total_page_count - 2 * self.plus
                    end_page = self.total_page_count
                else:
                    start_page = self.page - self.plus
                    end_page = self.page + self.plus
        page_str_list = []
        self.query_dict.setlist(self.page_param, [1])
        page_str_list.append('
首页
'.format(self.query_dict.urlencode()))
        if self.page > 1:
            self.query_dict.setlist(self.page_param, [self.page - 1])
            prev = '
上一页
'.format(self.query_dict.urlencode())
        else:
            self.query_dict.setlist(self.page_param, [1])
            prev = '
上一页
'.format(self.query_dict.urlencode())
        page_str_list.append(prev)
        for i in range(start_page, end_page + 1):
            self.query_dict.setlist(self.page_param, [i])
            if i == self.page:
                ele = '
{}
'.format(self.query_dict.urlencode(), i)
            else:
                ele = '
{}
'.format(self.query_dict.urlencode(), i)
            page_str_list.append(ele)
        if self.page < self.total_page_count:
            self.query_dict.setlist(self.page_param, [self.page + 1])
            prev = '
下一页
'.format(self.query_dict.urlencode())
        else:
            self.query_dict.setlist(self.page_param, [self.total_page_count])
            prev = '
下一页
'.format(self.query_dict.urlencode())
        page_str_list.append(prev)
        self.query_dict.setlist(self.page_param, [self.total_page_count])
        page_str_list.append('
尾页
'.format(self.query_dict.urlencode()))
        page_string = mark_safe("".join(page_str_list))
        return page_string

下面这个是我传二维数组的视图函数

#小波变换
def www(request):
    file_object = request.FILES.get("file")
    if file_object:
        data = xlrd.open_workbook(filename=None, file_contents=file_object.read())
        sheet = data.sheet_by_index(0)
        nrows = sheet.nrows
        list = []
        for i in range(1, nrows):
            list.append(np.array(sheet.row_values(i)))
        arr = np.array(list)
        p = pre()
        queryset = p.wave(arr)
        queryset = np.round(queryset,6)
        page_object = Pagination(request, queryset)  ########加这一句分页
        context = {"queryset": page_object.page_queryset,  # 分完页的数据
                   "page_string": page_object.html()  # 页码
                   }
        return render(request, 'wave2.html', context)
    return render(request,'wave.html')

下面这个是对应的前端页面

望采纳，Django分页组件需要接收一个可迭代的对象，所以传入的数据必须是一个可迭代的对象，比如列表、字典等。如果传入的是一个二维数组，则可能会导致分页组件失灵。
