Hi Alex,
Thank you for your purchase.

Can you please send me the link of that table so I can take a look and give you my suggestion.

Best regards.

HI Alex,

I will need an link of that table in order to inspect the element and see if it is possible to center the image.

You can also do it by yourself by clicking the right button and choose Inspect element.

Then the console will open and you can find the selector for that column.

Best regards.

Hi Alex,

Unfortunately I still can not predict the selector of that element and it will be much more easier if I can see the table live and find that selector.

Maybe this link can help you out.

When you find a selector from inspecting the element use the code from the link below to apply the desired CSS.

Best regards.

Hi Alex,

This is what I get when I try to access your page ( attachment) 

As a solution my suggestion is to take a look at our documentation about Styling the columns.

At the bottom of the documentation you will notice CSS classes.

For example give a CSS class for one of your columns with the image columnImage class.

Then in wpdatatables settings page in custom CSS field you can enter this code

table.wpDataTable td.columnImage{
text-align: center !important;
}

The only thing that can be time consuming is to add that custom CSS class to all of the columns where you have that images.

Best regards.
