Hi, Mike 

Firstly, I would like to sincerely apologize for the delayed response as we have been experiencing an unusually high number of tickets. I am sorry that it has taken longer than usual to respond to your concern and your patience is highly appreciated.

There can be different ways to achieve predefined filters for our tables.

-

If you wish to try Pre-filtering tables through URL,  please check out this page with examples.

-

You can also use placeholders for table generation.

1. For example, if you have a MySQL query-based table, you can use this query:

SELECT * FROM yourDatabaseTable
WHERE someColumn = %VAR1%

%VAR1% can be defined in the Placeholders tab when you're creating a table, 

then you can have multiple SQL Query-based tables that each have a different value filtered of that column.

2. 

Or, if you don't add the condition in an SQL query, you can add %VAR1% in column settings -> Filtering, under "Predefined filtering value".

Then, you can have different versions of the same table, with the VAR1 value passed in the shortcode,

let's say if we had a "Regions" column and we wish to filter a different region per each page.

If we want page 1 for example only filtered for "Region A" , you can set predefined filter to this column as %VAR1% (filter type has to be set as text) :

Then for a page where we need only Region 1 filtered, use shortcode [wpdatatable id=1 var1='Region A'] ,

 page 2 for only "Region B", shortcode would be [wpdatatable id=1 var1='Region B'] and so on, 

to apply the values defined in the shortcode to the filter.

( This filtering method can be used for any table type, besides Simple Tables)

I also made a short video example - please check it out here.

Let me know if that is what you needed.

Thank you
