这个show_in_admin_all_list 中的参数register_post_status() 函数确定给定的post状态是否包含在post表格视图中。

最短的版本可能是：

add_action( \'init\', function() use ( &$wp_post_statuses )
{
    $wp_post_statuses[\'draft\']->show_in_admin_all_list = false;

}, 1 );

add_action( \'init\', function()
{
    register_post_status( \'draft\',
        [
            \'label\'                     => _x( \'Draft\', \'post status\' ),
            \'protected\'                 => true,
            \'_builtin\'                  => true, 
            \'label_count\'               => _n_noop( \'Draft <span class="count">(%s)</span>\', \'Drafts <span class="count">(%s)</span>\' ),
            \'show_in_admin_all_list\'    => false, // <-- we override this setting
        ]
    );

}, 1 );

为了避免重复默认设置并支持将来可能的设置更改，我们可以使用get_post_status_object() 而是：

add_action( \'init\', function()
{   
    $a = get_object_vars( get_post_status_object( \'draft\' ) );
    $a[\'show_in_admin_all_list\'] = false; // <-- we override this setting
    register_post_status( \'draft\', $a );

}, 1 );

下面的代码将删除post 岗位类型。

查询参数all_posts 值为1 添加到菜单链接，以确保我们仅在必要时应用此修改（admin post filters（All，Mine，Published，Sticky，Scheduled，Drafts）下的所有链接将为我们添加此查询参数，但单击管理菜单时并非如此，因此我们需要自己添加它。

将下面的代码放入主题的functions.php 或者在插件中。

// Add a query argument to the Posts admin menu.
// This is used to ensure that we only apply our special filtering when needed.
add_action( \'admin_menu\', \'wpse255311_admin_menu\', PHP_INT_MAX );
function wpse255311_admin_menu() {
    global $menu, $submenu;

    $parent = \'edit.php\';
    foreach( $submenu[ $parent ] as $key => $value ){
        if ( $value[\'2\'] === \'edit.php\' ) {
            $submenu[ $parent ][ $key ][\'2\'] = \'edit.php?all_posts=1\';
            break;
        }
    }
}

// Hide draft posts from All listing in admin.
add_filter( \'pre_get_posts\', \'wpse255311_pre_get_posts\' );
function wpse255311_pre_get_posts( $wp_query ) {
    $screen = get_current_screen();

    // Ensure the the all_posts argument is set and == to 1
    if ( ! isset( $_GET[\'all_posts\'] ) ||  $_GET[\'all_posts\'] != 1 ) {
        return;
    }

    // Bail if we\'re not on the edit-post screen.
    if ( \'edit-post\' !== $screen->id ) {
        return;
    }   

    // Bail if we\'re not in the admin area.
    if ( ! is_admin() ) {
        return;
    }

    // Ensure we\'re dealing with the main query and the \'post\' post type
    // Only include certain post statuses.
    if ( $wp_query->is_main_query() && $wp_query->query[\'post_type\'] === \'post\' ) { 
        $wp_query->query_vars[\'post_status\'] = array (
            \'publish\',
            \'private\',
            \'future\'
        );
    }  
}
