## テーブル
複数のデータを同じような形式で表示します。データを並べ替えたり、フィルタリングしたり、テーブルで比較したりすることができます。
### 基本テーブル
基本テーブルはデータを表示するためだけのものです。
:::demo オブジェクトの配列で `el-table` の属性 `data` を設定した後、`el-table-column` の `prop` (配列 `data` に含まれるオブジェクトのキーに対応) を用いてテーブルのカラムにデータを挿入し、属性 `label` を用いてカラム名を定義することができます。また、属性 `width` を用いて列の幅を定義することもできる。

2021-09-04 19:29:28 +08:00
1 行選択に対応しています。
:::demo テーブルは 1 行選択をサポートしています。これを有効にするには、`highlight-current-row` 属性を追加します。行の選択が変更されると `current-change` というイベントがトリガされ、そのパラメータは変更後の行と変更前の行である `currentRow` と `oldCurrentRow` である。行のインデックスを表示したい場合は、新しい `el-table-column` を追加して `type` 属性を `index` に代入すると、1 から始まるインデックスが表示されます。

### 並び替え
データを素早く、見つけやすいまたは比較しやすいようにソート出来ます。
2021-09-04 19:29:28 +08:00
:::demo 特定のカラムに `sortable` 属性を設定し、そのカラムに基づいてデータをソートする。これは `Boolean` を受け付け、デフォルト値は `false` である。テーブル属性 `default-sort` を設定して、デフォルトのソート列と順序を決定する。独自のソートルールを適用するには、`sort-method` や `sort-by` を用いる。バックエンドからのリモートソートが必要な場合は、`sortable` を `custom` に設定し、テーブル上で `sort-change` イベントをリッスンします。イベントハンドラではソートカラムとソート順にアクセスできるので、API からソートされたテーブルデータを取得することができます。この例では、特定のカラムの値を整形するために `formatter` という名前の別の属性を使います。これは 2 つのパラメータを持つ関数を受け入れます。 `row` と `column` の 2 つのパラメータを持つ関数を受け付ける。この関数は、`row` と `column` の 2 つのパラメータを持つ関数を受け付ける。

### サマリー行
数字のテーブルの場合、各列の合計を表示するテーブルのフッターに追加行を追加することができます。
2021-09-04 19:29:28 +08:00
:::demo `show-summary` を `true` に設定することでサマリー行を追加することができる。デフォルトでは、サマリー行の最初のカラムは何も合計せずに常に 'Sum' を表示します (表示するテキストは `sum-text` で設定できます)。もちろん、独自の合計の振る舞いを定義することもできます。そのためには、`summary-method` に配列を返すメソッドを渡すと、配列の各要素がサマリー行の列に表示されます。この例の 2 番目の表に詳細なデモを示します。

### Custom index
`type=index` カラムで行のインデックスをカスタマイズすることができる。
:::demo 行のインデックスをカスタマイズするには、`el-table-column` の `type=index` で `index` 属性を用いる。これが数値に代入されている場合、すべてのインデックスはその数値のオフセットを持つことになる。また、各インデックス（`0`から始まる）をパラメータに持つメソッドも受け付けており、戻り値はインデックスとして表示される。
