我不完全确定这是否是你想要的，但是。。。下面的代码将注册一个短码，它将获得给定的行并输出该行的所有字段：

function shortcode_db_row_cb( $atts ) {
    $atts = shortcode_atts( array(
        \'id\' => false,
    ), $atts, \'db_row\' );

    global $wpdb;
    $row = $wpdb->get_row( $wpdb->prepare( "select * from {$wpdb->prefix}TABLE_NAME where id = %d", $atts[\'id\'] ), ARRAY_A );
    $res = \'\';

    if ( $row ) {
        $res = \'<table>\';
        $res .= \'<tr>\';
        foreach ( $row as $k => $v ) $res .= \'<th>\' . esc_html($k) . \'</th>\';
        $res .= \'</tr>\';
        $res .= \'<tr>\';
        foreach ( $row as $k => $v ) $res .= \'<to>\' . esc_html($v) . \'</td>\';
        $res .= \'</tr>\';
        $res .= \'</table>\';
        return $res;
    }

    return \'no such row\';
}
add_shortcode( \'db_row\', \'shortcode_db_row_cb\' );
