The filter for modifying, removing or adding columns to post list in WordPress admin panel is manage_{$post_type}_posts_columns.
Which hook you need to use for controlling the output of the column content depends on whether or not your post type is set to be hierarchical or not.
Any non-hierarchical post types, including WordPress’ built-in post type ‘post‘, use the hook name manage_{$post_type}_custom_column. Any hierarchical post types, including WordPress’ built-in post type ‘page‘, use the hook name manage_pages_custom_column (note: no injection of post type name in the hook name).
