Tableling is a table plugin based on Backbone.Marionette. It leverages Backbone and Backbone.Marionette components to provide an extensible table that can be easily integrated into existing Marionette applications. Tableling leaves the styling to you; this demo shows a table styled with Twitter Bootstrap.
Check out Tableling's documentation wiki. It explains the code used for this demo.
