table-magic

Allows you to seamlessly switch between CSV, TSV, HTML, SQL, markdown and a little form-based editor. Also allows you to preview the table as it would appear on GitHub.

Feature	Description
Renders markdown	Uses showdown library to render contents of table cells
Escapes quotes	Easier to edit without so only uses them when necessary
Preview table matches GitHub style	As closely as possible
Import HTML	Converts back and forth
Preserves alignment	Between all views
Markdown formatting	Adds spaces, makes things more legible
Form view	Create tables with buttons!

I've made this as a little learning exercise to play with Primer, Atom, GitHub Desktop and GitHub itself.

I keep an up-to-date version of this on my GitHub Pages site: http://table-magic.guntrip.co.uk/
