Hi, Brian

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.

These export functionalities are based on a 3rd party HTML5 library. There are some limitations in this library

Unfortunately, you can not export columns that are hidden – they will not be visible in any exporting or printing tool.

More details about it here.

We might try to add functionality for this in the future, but I can't say an ETA on it.

You can suggest this as a built-in feature on this link https://wpdatatables.com/documentation/feature-suggestion/ and our developers would place it on their "TO-DO" list.

As more customers request a feature, it gets pushed quicker on the list. We always strive to make our product better and deliver the most value to our end users, so we carefully review each suggestion.

Hi, Brian

Terribly sorry for taking so much time on this.

I did my best efforts to find any workarounds for this but unfortunately did not find any.

Maybe it can be done with a high level of custom work, but I am not sure, to be honest.
Our developers are very busy at the moment, working on some priority tasks and fixing bugs and issues with our plugins, so they won't be having the time for custom work in the near future.

We can recommend reaching out to someone who does custom solutions, such as WP Kraken,
but we can't advise on their pricing.
