| "I've been working on making presentations in IPython lately. I often end up using tables in my presentations and publications, and wanted a way to format them nicely from IPython notebooks. So I added the PrettyTable class, along with some basic themes, to [my fork of ipywidgets](https://github.com/mgymrek/ipywidgets). This allows for easily formatting the way tables are displayed. This is similar in spirit to the [ipy_table](http://github.com/epmoyer/ipy_table/) repository, but with more modular themes and the ability to add any property to tables that you can do with CSS.\n", | |
