Hi, Clement

Sorry for the delay

Yes. The easiest way to achieve this is, you can create one "main table" for Administrators to edit,

and you can make an SQL Query from this table, to present this one for front-end clients.

For example, main Manual table;

And then find what is the SQL name of the table on the Editing tab, like this :

Make a new SQL Query based table, like this :

SELECT * FROM wp_wpdatatable_4  

( In your case it can be different table number):

And you will have another table, that you can place on the page for clients;

This table will pull data from the main table, and you can set only certain columns - to be edited;

for columns you don't wish to allow them to edit, just set Editor Type as NONE :

Let me know how this sounds? Thank you
