Table for logged in users

Hi,

thanks for your post, and sorry for the trouble.

Something like this is not possible natively, so that using an extra plugin might be the best. You could also use a simple code solution like http://justintadlock.com/archives/2009/05/09/using-shortcodes-to-show-members-only-content

Another idea is to hide certain rows/column to logged-out users, via the TablePress Extension from https://tablepress.org/extensions/hide-data-logged-out-users/. After installing and activating that, you could use a Shortcode like
[table id=123 hide_rows_logged_out="3-8" /]
to hide rows 3 through 8 from users that are not logged in.

Regards,
Tobias
