这并不容易，因为没有钩子来添加行操作。但是，您可以取消注册日期列，并使用添加的行操作重新注册自己的日期列。不幸的是，有点黑。

我已尝试确保以下代码适用于帖子类型“推荐”

首先注册新的日期列，然后注销旧的：（使用manage_{post_type}_posts_columns 挂钩）

add_filter(\'manage_testimonials_posts_columns\', \'my_custom_date_column_head\'); 
function my_custom_date_column_head($columns) {  
    $columns[\'date2\'] = \'Date\';  
    unset( $columns[\'date\'] );
    return $columns;  
}

然后使新的日期列可排序（按“日期”）。使用manage_edit-{post_type}_sortable_columns 挂钩）

add_filter( \'manage_edit-testimonials_sortable_columns\', \'my_custom_date_column_sort\' );
function my_custom_date_column_sort( $columns ) {
    $columns[\'date2\'] = \'date\';
    return $columns;
}

现在是有趣的一点-显示专栏的内容。我几乎复制并粘贴了WordPress用来填充日期列的内容，然后在末尾添加了操作。

使用manage_{post_type}_posts_custom_columns 挂钩）

add_action( "manage_testimonials_posts_custom_column", \'my_custom_date_column_content\',10,2);
function my_custom_date_column_content($column, $post_id ){
    global $post,$mode;

    if( \'date2\' != $column )
        return;

    //**** Display default content of date column *******//

    if ( \'0000-00-00 00:00:00\' == $post->post_date ) {
        $t_time = $h_time = __( \'Unpublished\' );
        $time_diff = 0;
    } else {
        $t_time = get_the_time( __( \'Y/m/d g:i:s A\' ) );
        $m_time = $post->post_date;
        $time = get_post_time( \'G\', true, $post );

        $time_diff = time() - $time;

        if ( $time_diff > 0 && $time_diff < 24*60*60 )
            $h_time = sprintf( __( \'%s ago\' ), human_time_diff( $time ) );
        else
            $h_time = mysql2date( __( \'Y/m/d\' ), $m_time );
    }

    if ( \'excerpt\' == $mode )
        echo apply_filters( \'post_date_column_time\', $t_time, $post, $column, $mode );
    else
        echo \'<abbr title="\' . $t_time . \'">\' . apply_filters( \'post_date_column_time\', $h_time, $post, $column, $mode ) . \'</abbr>\';

    echo \'<br />\';

    if ( \'publish\' == $post->post_status ) {
        _e( \'Published\' );

    } elseif ( \'future\' == $post->post_status ) {
        if ( $time_diff > 0 )
            echo \'<strong class="attention">\' . __( \'Missed schedule\' ) . \'</strong>\';
        else
        _e( \'Scheduled\' );

    } else {
