In Confluence, there is no option to move items around through drag & drop and it would require the user has the option to manually copy and paste the content (crtl/cmd+c/v).

For tables, depending on its size, it would be toilsome for the user to have to select all the content
and have it placed in a different part of the page. This would be a feature request to provide an additional method to copy and paste tables with a button in the editor, which would make it to not carry any formatting tied to the table as well.
