Hello John

Thank you for your interest in our plugin.

wpDataTables has calculation functions which are used to display MIN or MAX values of that column, and to calculate AVG and SUM values of that column.

Then, there are Formula columns which are used to calculate data between columns depending on the formulas you define in those columns. Unfortunately, you can't combine formula columns and calculation functions.

When you take a look at the documentation, please try out our sandbox site, where you can test these and all other features of the plugin.

Hi again Krzysztof

You can apply the Number Range Slider as a filtering option for Integers and Floats. However, one number range slider applies only to the table it's coming from - it cannot affect multiple tables. So, all this data should be in the same table.

The plugin doesn't have any comparing features, so something like this would need to be done as a custom solution.
