Fail to Display dataframe in DataTable

Greetings, I am trying to display my dataframe on webpage using flask and datatable . Here is minimal code for data-table.

        if display == "display":
            source = ColumnDataSource(dataframe)

            Columns = [TableColumn(field=Ci, title=Ci) for Ci in dataframe.columns]  # bokeh columns
            # source = ColumnDataSource.from_df(data)
            data_table = DataTable(columns=Columns, source=source)
            script,div = components(data_table)

While executing above code I am getting an error(shown in below image)

I am not able to detect why I am getting this error.

Thanks in advance.

Hi @internshipdeco, that is not a minimal example. A minimal example is one that can be copy-pasted in to an editor, and immediately run, self-contained, without any modifications whatsoever. If you can provide a minimal reproducer, I will be happy to run it and investigate.

Sorry for late response.
I have figured out, why I am getting that error. This error " Error: SlickGrid’s ‘enableColumnReorder = true’ option requires jquery-ui.sortable module to be loaded " occurs when I am using “jquery-1.12.4.js, jquery-ui.js” in my webpage.

THIS IS MY CORRESPONDING PYTHON CODE:

from bokeh.layouts import column
from bokeh.models import ColumnDataSource
from bokeh.plotting import figure
from flask import Flask, render_template, request
import pandas as pd
from bokeh.embed import components
from bokeh.models.widgets import DataTable, TableColumn, StringFormatter

app = Flask(__name__)

def fig(data):
     source = ColumnDataSource(data=dict(index=[], HIGH=[]))
     source.data = source.from_df(data)
     #print(source.data)
     ts1 = figure(plot_height=350,plot_width=1300,sizing_mode='scale_width',    
   active_drag="box_zoom", toolbar_location="left", y_axis_label='PRICE')
    ts1.line('index', 'HIGH', source=source, color="green")
    layout = column([ts1])
    return  layout

@app.route('/', methods = ['GET', 'POST'])
def index():
    data = {
    "HIGH": [833.31, 832.38, 828.84, 818.25, 817.2, 811.59, 798.39, 798.5, 801.3, 806.59, 806.15, 804.25, 800.34,
             787.64, 785.22, 786.23, 785.67, 775.16, 764.28, 761.91]}
    dataframe = pd.DataFrame(data)
    chck_box = request.args.get("display_data")
    plot = fig(dataframe)
    ' '''''
    source = ColumnDataSource(dataframe)

    # Columns = [TableColumn(field=Ci, title=Ci) for Ci in dataframe.columns]  # bokeh columns
    # source = ColumnDataSource.from_df(data)
     columns = [
        TableColumn(field='HIGH', title='High',
                    formatter=StringFormatter(text_align="center")),
    ]
data_table = DataTable(columns=columns, source=source, width=700, height=380)
     script1, div1 = components(data_table)
     script, div = components(plot)
     return render_template("table.html", script=script, div=div, script1 =script1, div1=div1)
 if __name__ == '__main__':
       app.run(debug=True)

When I use “jquery-1.12.4.js, jquery-ui.js” in my webpage, I get that error, after removing
**"script src=“https://code.jquery.com/jquery-1.12.4.js” and **
script src=“https://code.jquery.com/ui/1.12.1/jquery-ui.js from web page everything works fine.

I think there might be some compatibility issue between bokeh-tables-1.3.1.min.js and jquery-1.12.4.js, jquery-ui.js…

Any suggestion would be great for me. Please help…
Thanks in advance.

That’s entirely possible. Unfortunately, the only suggestion I have is to use one of the jquery versions that does work, and avoid the ones that don’t. Or alternatively, to not use enableColumnReorder.

It would be reasonable to make a GitHub issue about this, with full information to reproduce, and that would be good to have to keep track of this. But just being up front, it’s probably not something any of the few core devs would be able to prioritize very soon.

Thank you for your time. I have created two different web page for time-being and that works fine.
