Hello soportesv.

Thank you for your purchase.

This may not be achieved as easily as one might think. You can add a rule like this:

and then apply the following CSS in Custom CSS under main settings of wpDataTable:

table.wpDataTable tbody tr td.test{
display: none !important;
}

but that would just hide the column's contents and move the others to the left. So, you'd still have the header and footer active, which cannot be removed dynamically, by adding the conditional rule:

That just looks bad.

You can add this CSS:

table.wpDataTable tbody tr td.test{
opacity: 0 !important;
}

so the table looks like this:

Now it hid the contents of the first column.

So, there's no way of dynamically hiding the entire column using rules.

Fixed table header would be considered a custom solution, and you can take a look at this link to see if it gives you some ideas as to how it can be implemented.

Please note that customization questions like this one are not covered in the included support for the plugin. Included support covers help with bugs and general inquiries for the plugin features, but not writing custom code. As you're developing some custom solution if you need our assistance we can offer you our paid customization service.

Sorry for any inconvenience.

Best regards.
