我正在尝试对现有数据框实施某些样式设计,但一直出现错误。我尝试按照看似简单明了但似乎找不到this issue

的答案的pandas文档进行操作

我试图在移动到数据透视表之前查看df.style是否在为我的表工作,但是它没有显示模板中的任何更改。

DataFrame:

           DATE  FINAL_SCORE   FN    G    L  MODEL_SCORE    R   RV   SN   TC TICKER_id     id
0    2019-05-20          1.5  1.5  0.0  0.0          1.5  0.0  1.5  1.5  1.0       EWA   0001
1    2019-05-21          1.5  1.5  0.0  0.0          1.5  0.0  1.5  1.0  1.0       EWA   0002
2    2019-05-22          1.5  1.5  0.0  0.0          1.5  0.0  1.5  1.0  1.0       EWA   0003
3    2019-05-23          1.5  1.5  0.0  0.0          1.5  0.0  1.5  1.0  1.0       EWA   0004
4    2019-05-24          1.5  1.5  0.0  0.0          1.5  0.0  1.5  1.0  1.0       EWA   0005

这是我的views.py index()color_negative_red()的一部分:

def color_negative_red(val):
    color = 'red' if (-2.0 <= val >= 2.0) else 'black'
    return 'color: %s' % color

def index(request):
    scores = overall_scores.objects.filter(TICKER__in = countries, DATE = last_date).values()
    lag_scores_df = pd.DataFrame([x for x in overall_scores.objects.filter(TICKER__in = countries, DATE__gte = lag_date).values()])
    lag_scores_df = lag_scores_df.pivot_table(index = 'DATE', columns = 'TICKER_id', values = 'FINAL_SCORE')
    lag_scores_df.style.applymap(color_negative_red)
    sector_top_scores = sorted(sector_scores, key = lambda i: i['FINAL_SCORE'], reverse = True)[:5]
    context = {'sorted_top_scores': sorted_top_scores}
    return render(request, template, context)

index.html:

        <table class="table table-hover">
            <thead>
                <tr>
                    <th scope="col">Ticker</th>
                    <th scope="col">Final</th>
                    <th scope="col">G</th>
                    <th scope="col">L</th>
                    <th scope="col">R</th>
                    <th scope="col">FN</th>
                    <th scope="col">RV</th>
                    <th scope="col">SN</th>
                    <th scope="col">TC</th>
                    </tr>
            </thead>
            <tbody>
                {% for ticker in sorted_top_scores %}
                <tr>
                    <td>{{ ticker.TICKER_id }}</td>
                    <td>{{ ticker.FINAL_SCORE }}</td>
                    <td>{{ ticker.G }}</td>
                    <td>{{ ticker.L }}</td>
                    <td>{{ ticker.R }}</td>
                    <td>{{ ticker.FN }}</td>
                    <td>{{ ticker.RV }}</td>
                    <td>{{ ticker.SN }}</td>
                    <td>{{ ticker.TC }}</td>
                </tr>
                {% endfor %}
            </tbody>
        </table>
