We created a Sandbox site so that you could try our WordPress table plugin before you buy it. It has a number of pre-defined WordPress tables illustrating the plugin features, and you’re free to create a table in WordPress and see how the plugin works.

Also is available free wpDataTables Lite version of the plugin. While some of the premium features are reduced, wpDataTables Lite is still quite a handy tool which would allow you to quickly create tables in WordPress from different sources: Excel, CSV, JSON, XML and Serialized PHP array.
