Hello Ron.

There aren't built-in features that would allow you to do this, but you can count the number of rows with some custom MySQL Queries.

Our logic is based on a PHP SQL parser which has full support for the SQL dialect for the following statement types

SELECT, INSERT, UPDATE, DELETE, REPLACE, RENAME, SHOW, SET, DROP, CREATE INDEX, CREATE TABLE, EXPLAIN and DESCRIBE.

Some of them are disabled for security reasons.

Filtering, sorting, and searching may not work properly if you include:

• Accent graves ( ` ) around the table name
• JOIN functions
• UNION functions
• CONCAT functions
• sub-queries

You can try preparing a MySQL view (which will return the data that you need, call it e.g. “view1” and then build a wpDataTables based on a simple query like "SELECT * FROM view1″.
