Add Options to display DataFrame Index

[Sinhrks]

Thanks for the great package!

Currently, spyre doesn't render DataFrame index by default. Is it reasonable to add an option to switch the behaviour?

Also, there is a bug when a DataFrame has a named Index. Pls see the below image which has unnecessary row.

from spyre import server

import numpy as np
import pandas as pd

idx = pd.Index(list('ABCDE'), name='index')
df = pd.DataFrame(np.random.randn(5, 5), index=idx)

class Example(server.App):

    tabs = ['example']
    outputs = [{"output_type" : "table",
                "output_id" : "table_id",
                "tab" : "example",
                "on_page_load" : True }]

    def getData(self, params):
        return df

app = Example()
app.launch(port=9093)

Sorry, I found the latter bug is caused by pandas.DataFrame.to_html() side. I've issued pandas-dev/pandas#10344.

What I would like to ask you in this issue is whether adding an option to draw Index is reasonable because Index can contain meaningful information such as datetime.

@sinhrks couldn't you just call the .reset_index() method on the dataframe?

[Sinhrks]

Possible as a workaround, but DataFrame.index often contain important information. I think it is better to always display index if there is no switching option.

@sinhrks i've addressed this issue here and here

to include the index column in your tables put:
server.include_df_index = True
at the top of your app after you import the server class.
