除了composer安装，直接下载的怎么配置？

下载好了之后，放在vendor文件下面，然后配置一下yiisoft下面的exetension.php里面的配置就可以的，难点在于按照yii框架的类自动加载机制配置好别名

参照yii\grid\GridView的这两个方法

public function renderTableBody()
    {
        $models = array_values($this->dataProvider->getModels());
        $keys = $this->dataProvider->getKeys();
        $rows = [];
        foreach ($models as $index => $model) {
            $key = $keys[$index];
            if ($this->beforeRow !== null) {
                $row = call_user_func($this->beforeRow, $model, $key, $index, $this);
                if (!empty($row)) {
                    $rows[] = $row;
                }
            }

            $rows[] = $this->renderTableRow($model, $key, $index);

            if ($this->afterRow !== null) {
                $row = call_user_func($this->afterRow, $model, $key, $index, $this);
                if (!empty($row)) {
                    $rows[] = $row;
                }
            }
        }

        if (empty($rows)) {
            $colspan = count($this->columns);

            return "<tbody>\n<tr><td colspan=\"$colspan\">" . $this->renderEmpty() . "</td></tr>\n</tbody>";
        } else {
            return "<tbody>\n" . implode("\n", $rows) . "\n</tbody>";
        }
    }

public function renderTableRow($model, $key, $index)
    {
        $cells = [];
        /* @var $column Column */
        foreach ($this->columns as $column) {
            $cells[] = $column->renderDataCell($model, $key, $index);
        }
        if ($this->rowOptions instanceof Closure) {
            $options = call_user_func($this->rowOptions, $model, $key, $index, $this);
        } else {
            $options = $this->rowOptions;
        }
        $options['data-key'] = is_array($key) ? json_encode($key) : (string) $key;

        return Html::tag('tr', implode('', $cells), $options);
    }

@Edwin 看源码啊

@Edwin 具体通过这个来设置的
$keys = $this->dataProvider->getKeys();
