manage_<id>_columns

Description

apply_filters( 'manage_<id>_columns', (array) $array ); 

The dynamic portion(s) of the hook name refer to the ID of a specific screen. For example, the screen ID for the Posts list table is edit-post, so the filter for that screen would be manage_edit-post_columns.
