The above one is the complete code to create row actions. This is one of my convenient way to use use row actions.  Here my db name is

” wp_kv_pluginpress. ” here i listed all the plugins. this is just for understanding.  and “kvcodes_edit_plugins” is the main function to create object and perform row actions too.
