centos和windows之间使用jinja2的渲染结果不同

Question

我试图输出一个自定义样式的熊猫数据框到html。 我无法理解的一个问题是，当代码在Centos中呈现时，整数被呈现为float。windows上不会发生这种情况。你知道吗

输出

我找到了解决办法。你知道吗

通过检查代码，我发现给定的模板没有正确呈现。原因是round(precision)。你知道吗

所以，我改变了原来的模板一点，以“修复”它。 具体来说，我变了

        {% if c.value is number and c.value|int < c.value %}
                 {{c.value|round(precision)}}
        {% else %}
                 {{c.value}}
        {% endif %}

最初是{% if c.value is number %}。你知道吗

from jinja2 import Template

template = Template("""
        <style  type="text/css" >
        {% for s in table_styles %}
            #T_{{uuid}} {{s.selector}} {
            {% for p,val in s.props %}
                {{p}}: {{val}};
            {% endfor %}
            }
        {% endfor %}
        {% for s in cellstyle %}
            #T_{{uuid}}{{s.selector}} {
            {% for p,val in s.props %}
                {{p}}: {{val}};
            {% endfor %}
            }
        {% endfor %}
        </style>
        <table id="T_{{uuid}}" {{ table_attributes }}>
        {% if caption %}
            <caption>{{caption}}</caption>
        {% endif %}
        <thead>
            {% for r in head %}
            <tr>
                {% for c in r %}
                <{{c.type}} class="{{c.class}}">{{c.value}}
                {% endfor %}
            </tr>
            {% endfor %}
        </thead>
        <tbody>
            {% for r in body %}
            <tr>
                {% for c in r %}
                <{{c.type}} id="T_{{uuid}}{{c.id}}" class="{{c.class}}">
                {% if c.value is number and c.value|int < c.value %}
                         {{c.value|round(precision)}}
                {% else %}
                         {{c.value}}
                {% endif %}
                {% endfor %}
            </tr>
            {% endfor %}
        </tbody>
        </table>
        """)

st = pd.core.style.Styler(v1)
st.template = template
st.render()

我仍然不知道为什么不同的平台呈现出不同的效果。你知道吗
