Delete plug-in

I had to delete the spreadsheet plug-in because I was continually getting an error message in my error logs. I erased the plug-in using the delete button in my WordPress dashboard but I am still getting the error messages. Is there something in my database that I should erase as well? There are a bunch of tables in my database that I think are created by the plug-in. They all start with WP_DHX_… For example one of them is WP_DHX_data. Were they created by the plug-in? Any help would be greatly appreciated thanks

could you provide details about error message?
Here is a list of created database tables:

You may delete all of them if you don’t need the data of spreadsheet anymore.
