Displaying arbitrary HTML using Hovertool

Hi,

Upon a mouse-over event, I’d like to use the hover tool to display arbitrary HTML. Basically, what I"m doing is this:

for idx in plot_df.index:

plot_df.loc[idx, ‘html_str’] = post_peer_review.loc[idx, [col1, col2]].to_html()

and then turning plot_df into a ColumnDataSource, and using the hovertool to display ‘html_str’. This however quotes the html, and does not display it.

Unfortunately, I cannot put the actual html into the hovertool and refer to values in the ColumnSource, because the information is coming from a separate dataframe and contains a variable number of rows. It would of course be possible to put some clever javascript to nicely format a table depending on row numbers, but it would be much nicer to let pandas handle that for me.

Is there a way to get the hovertool to display the html without quoting it?
