Hello Irfan

Thank you for your interest in our plugin.

wpDataTables can't be used to create databases but if you're referring to pulling the data from the database where only 3 values of a certain column are selected, you can do that with some custom SQL query.

Something like the queries mentioned here.

Please note: Using this plugin feature requires at least a basic knowledge of SQL. It is assumed that you can create the table in some MySQL data manager (e.g., PHPMyAdmin, MySQL Workbench), and prepare a SQL query that will return the data you need. If you do not know how to use MySQL, refer to the “Create a MySQL-query-based table by generating a query to MySQL database” section. It will explain how to create complete tables or MySQL queries without this basic knowledge. Please be advised that preparing MySQL queries for you is not included in the plugin support.
