Hi, milan.

Sorry for the delayed response.

-

Yes. There is a workaround for this use-case with our premium plugin.

We have advanced filters available, which you can use to predefine a filter for the "user ID" column.

I will show you an example.

- First we add that hidden "user_id" column on the source Form, which you can hide in our plugin from the front-end if needed. 

We will then add a predefined filter value to this column, using a PlaceHolder "%CURRENT_USER_ID%";

- Check that the filter type is set as "Text", as shown on this screenshot.

- Here is how an example table linked to a source file looks before we make any changes, with visible filters above the table.

And now, when we set the pre-filter, with Administrator logged in ( In our case, the user ID is 1), we only see rows matching that user ID.

- (If you need more detailed information about using Placeholders in wpDataTables, here is our documentation about that https://wpdatatables.com/documentation/table-features/using-placeholders/);

- The user_ID filter is still visible, which means, if someone changes/deletes this value, they could see the whole table.

We will hide it from the front-end with some custom CSS added in the "Customize" section of the main table settings.

- It should be easy to do, depending on your knowledge of HTML and CSS.

You have to find the correct selector using the browser inspector tool, add the style "display:none" property to it, and it will disappear from the front-end.

On our example table, the custom CSS is :

#table_1_5_filter_sections  {
    display:none; }

- Now, the user_ID filter is gone from the front-end.

- Optionally, you can hide the user_id column from the front-end, if needed, either using the column settings tab or the "column list" button from the back end Admin area.

- If you need more details about this, don't hesitate to contact us further.

And i just wanted to point out that you can try wpDataTables before purchasing

 on our sandbox Demo sites ( you can find links for the main plugin Demo,  

as well as add-on Demos, in my signature),

and there is a 15-day money-back guarantee period, 

so if you purchase the plugin, you can safely fully test it out, and if it doesn't fit your needs you can request and receive a refund in that period. ( same goes for all plugins and add-ons)

Let me know if you have any additional questions.
