Moodle自定义区块开发问题：HTML表格显示位置异常

问题根源在于你直接使用echo输出表格，这会把内容直接发送到页面输出流，导致表格显示在页面顶部而非区块内部。正确的做法是将表格的HTML内容赋值给区块的content->text属性。

修改后的代码如下：

class block_scorecard extends block_base {

    function init() {
        $this->title = get_string('pluginname', 'block_scorecard');
    }

    function get_content()  {
        global $DB;

        if ($this->content !== NULL) {
            return $this->content;
        }

        $courses = $DB->get_records('scorm_scoes_track', ['element' => 'cmi.core.total_time']);
        $table = new html_table();
        $table->head = array('No of attempts','Time modified','status');
        
        foreach ($courses as $course) {
            $attempt = $course->attempt;
            $timemodified = userdate($course->timemodified, get_string('strftimerecentfull'));
            $status = $course->value;
        
            $table->data[] = array($attempt, $timemodified, $status);
        }

        // 关键修改：将表格HTML赋值给content文本，而非直接echo
        $this->content = new stdClass;
        $this->content->text = html_writer::table($table);       
        return $this->content;
    }
}

核心修改说明： #

• 移除了直接输出表格的echo html_writer::table($table);语句
• 将html_writer::table($table)生成的HTML字符串直接赋值给$this->content->text
• 补充了return $this->content，确保区块能正确返回渲染内容
