Problem with html.Iframe

I am trying to load and print all the console output into Dash. Tried Markdown first but not working well. Then I used html.Iframe. The place where I got stuck is it is not showing the white-space of the tables in the text file. For example below:

Here is my code:

the ‘white-space’:’ pre-wrap’ seems not working to do the job. I am curious how I can fix this or if there is a better way to show this txt. Thanks

import dash
import dash_core_components as dcc
import dash_html_components as html

text_markdown = “”
f = open(‘stdout.txt’)
line = f.readline()
text_markdown = “”
while line:
text_markdown += “
”+line
line = f.readline()
f.close()

app = dash.Dash(name)

app.layout = html.Div([
html.Div([

dcc.Markdown(text_markdown)

                       html.Iframe(

                               srcDoc = text_markdown,
                               style={'border': 'none', 'width': '100%', 'height': 600,'white-space':' pre-wrap'},)
            ])

])

if name == ‘main’:
app.run_server(debug=False)

Here is a sample text file:

The file has these tracks: [‘DEN’, ‘DT’, ‘DT_SHEAR’, ‘GR’, ‘NET_SAND_LRP’, ‘NEU’, ‘POR_LRP’, ‘POR_SAND_LRP’, ‘RES_DEP’, ‘SWT_LRP’, ‘SWT_SAND_LRP’]

Problem was solved by switching to dcc.Textarea
