【问题描述】：
有一些使用Flask 执行此操作的示例，因此理论上Pyramid 也应该可以这样做，但到目前为止，还不能。我正在尝试使用Pyramid web framework 中的DataTables JS 库显示 Pandas 数据框。这是我的文件夹/文件结构：
repo_name/
modules/
get_df.py
static/
theme.css
templates/
layout.jinja2
mytemplate.jinja2
views/
__init__.py
default.py
routes.py
development.ini
production.ini
setup.py
这些文件中的大部分都没有受到 Pyramid cookiecutter 代码here 的影响。但是我编辑的文件粘贴在下面。
views/default.py
from pyramid.view import view_config
from repo_name.modules.get_df import main
@view_config(route_name='home', renderer='../templates/mytemplate.jinja2')
def my_view(request):
df = main()
html_table = df.to_html(table_id='myTable')
return dict(project='my_project', table=html_table)
mytemplate.jinja2
{% extends "layout.jinja2" %}
{% block content %}
<div class="content">
<h1><span class="font-semi-bold">Pyramid</span> <span class="smaller">Starter project</span></h1>
<!-- <p class="lead">Welcome to <span class="font-normal">{{project}}</span>, a Pyramid application generated by<br><span class="font-normal">Cookiecutter</span>.</p> -->
<p class="lead">Welcome to <span class="font-normal">{{project}}</span>, a Pyramid application generated by<br><span class="font-normal">Cookiecutter</span>.</p>
</div>
{% endblock content %}
{% block additional_scripts %}
<!-- <script type="text/javascript" src="../static/mytemplate.js"></script> -->
<script type="text/javascript">
$(document).ready(function() {
$('#myTable').DataTable();
});
</script>
{% endblock %}

生成的网页不显示 DataTable 或原始 HTML 表格，它只显示带有 CSS 格式的默认 HTML 文本。对此的任何帮助将不胜感激！
