Color rows of pandas dataframe and convert to HTML table

Question

I am trying to show a pandas dataframe using flask. I was successfully doing so, until I decided to colour some of the dataframe\'s rows. In particular I fail when I apply t

Answer 1

As the error message indicates, you are trying to use the DataFrame.to_html() method on a Styler object, since df.style.apply returns a Styler object and not a DataFrame.

The docs say you can use the render() method to render the HTML.

Something like this:

style1 = df.style.apply(highlight_greaterthan,threshold=1.0,column=['C','B'], axis=1)
df_html = style1.render()

The output of style1.render() would be:
