Rise: Markdown table rendering

[kakila]

For some reason tables are rendered very small, I can zoom into them to see the content, of course, this makes other parts of the slide not visible.
Is there a way to increase the overall size (respect to headers, text, etc...) of rendered tables?

Seems related to #175 and #255

From the links you have posted I found that including a cell at the top of the notebook with

%%HTML
<style>
.rendered_html table, .rendered_html th, .rendered_html tr, .rendered_html td {
     font-size: 100%;
}
</style>

seemed to fix table output.

Thanks for the info, we can probably add this piece to the rise.css...

Thanks @eitanlees, but I am running IJulia. I guess that's a solution for python
In julia I get

UndefVarError: Markdown not defined

@kakila Would changing %%HTML to %%html work, as suggested below?

@kakila In IJulia you can use the following in a Julia code cell, Julia do not have magic commends.

HTML("""
<style>
.rendered_html table, .rendered_html th, .rendered_html tr, .rendered_html td {
     font-size: 100%;
}
</style>
""")

I had a presentation with many Pandas dataframes displayed, and they were all coming out smaller than the text. The solution from @eitanlees above fixed my problem. Thank you!

Is this something that needs to be changed in Pandas, or in RISE? If the former, I could do a pull request if I had a bit better of an idea of what needs to be changed... If the latter, this is a problem that pretty much anyone building RISE presentations for notebooks that use Pandas will encounter.

IMHO, we should fix it on RISE, it is just a matter to include that css in the main.less (https://github.com/damianavila/RISE/blob/master/src/less/main.less) and check that we are not breaking other table-related stuff.

Happy to review a PR if you want to make a try!
