python - pandas 数据框 - 索引列标题较低。为什么？

Question

我希望索引列标题“日期”与所有其他列位于同一行。现在，它低一排。我怎样才能解决这个问题？

@app.route('/closeprice', methods=['POST']) #route tells Flask what URL should trigger the function
def closeprice():    
    tickersym = request.form['ticker']
    pandas_ds = get_historical_data(tickersym, start, end, output_format='pandas')
    pandas_ds['closechg']=pandas_ds.close.pct_change() #closing daily change 
    server_data = (pandas_ds.style.applymap(color_negative_red, subset=['closechg']).format({'closechg':"{:.2%}"})).render()
    return render_template('view.html',tickersym=tickersym,tables=[server_data],titles = tickersym)

请尝试以下操作:

df.columns.name = df.index.name
df.index.name = None
