How to print table using Jinja2 (without page refresh)

The jinja template that you need is something like this:

<table border="1" class="dataframe">  <thead>    <tr style="text-align: right;">      <th></th>      <th>Part_number</th>      <th>Type_name</th>      <th>Short_desc</th>      <th>Price_1</th>      <th>Price_2</th>      <th>VAT</th>      <th>DB_source</th>    </tr>  </thead>  <tbody>      {% for row in mydata %}          <tr>                 <th>{{loop.index0}}</th>                <td>{{row['Part_number']}}</td>                <td>{{row['Type_name']}}</td>                <td>{{row['Short_desc']}}</td>                <td>{{row['Price_1']}}</td>                <td>{{row['Price_2']}}</td>                <td>{{row['VAT']}}</td>                <td>{{row['DB_source']}}</td>          </tr>      {% endfor %}  </tbody></table>

Check jinja2 documentation for more details

Sure Here is my code for html template:

{% extends "header.html" %}{% import "bootstrap/wtf.html" as wtf %}{% block content %}<div class="container"><form class="form-signin" method="POST" action="/search">    <div class="panel panel-default">        <div class="panel-heading">Service Part Inquiry</div>        <div class="panel-body">{{ form.hidden_tag() }}{{wtf.form_field(form.FGPN_Search)}}{{wtf.form_field(form.AssyTypeName_Search)}}{{wtf.form_field(form.Source_Search)}}<button type="submit" class="btn btn-primary btn-xsy">Search</button> </div>    </div></form></div> <!-- /container -->    {{data|safe}}    {% endblock %}

Code for function below. Actually I check condition only for "Source_Search": "Murexin", that why I deleted some codes (will be easier to understand for You :) I respect Your time):

    @app.route('/search',methods=['GET', 'POST'])    def search():        form = SearchForm()        if request.method == 'POST':            FGPN_Search = form.FGPN_Search.data            AssyTypeName_Search = form.AssyTypeName_Search.data            Source_Search = form.Source_Search.data        (...)            elif Source_Search == 'Murexin':                if len(FGPN_Search)>1:                    tablePLM=read_sql_query(select1 + "\'" + FGPN_Search + "\'" + select2 + "\'" + AssyTypeName_Search + "\'",CurDB_2)                    tableSIC = read_sql_query(selectSIC + "\'" + FGPN_Search + "\'",CurDB_1)                    mydata = pd.merge(tablePLM, tableSIC, on='PM_PARTNUMBER',how='outer')                    mydata.to_html()                            return render_template('search.html', form=form,data=mydata)            elif Source_Search == 'test':                return "<h1>test</h1>"            else:                flash("Please write anything.")                return render_template('search.html',form=form)        return render_template('search.html', form=form)
