DataTables is open source and is actively being developed to add new features and plugins, and fix bugs.
DataTables works well with Bootstrap, Foundation, and jQuery UI. A list of existing themes that support DataTables are listed on their site.
Handsontable provides easy to follow tutorials for those new to the plugin, detailed documentation on using the features and examples of the plugin in use.
Cells that are filled out with non-Latin script such as Korean, Japanese, Chinese, etc display the first character as Latin.
Handsontable was developed and is currently supported by the development team at [Handsoncode] (http://handsoncode.net/)
