Hi,
Tablepress tables are not actually possible to return as results (it is only a storage post type for the table contents), but used as shortcodes within post type contents.
When using the index table engine, the plugin will automatically parse the contents from the tablepress tables and return the posts containing the tables.
If you need exact word matches, I recommend using the “AND with exact keyword matches” when using the index table: https://i.imgur.com/FVlJMYG.png
