 :::demo After setting attribute `data` of `el-table` with an object array, you can use `prop` (corresponding to a key of the object in `data` array) in `el-table-column` to insert data to table columns, and set the attribute `label` to define the column name. You can also use the attribute `width` to define the width of columns.

If you need to display row index, you can add a new `el-table-column` with its `type` attribute assigned to `index`, and you will see the index starting from 1.

 ### Sorting
@@ -927,27 +829,18 @@ You can also select multiple rows.
 Sort the data to find or compare data quickly.
 
 :::demo Set attribute `sortable` in a certain column to sort the data based on this column. It accepts `Boolean` with a default value `false`. Set table attribute `default-sort` to determine default sort column and order. To apply your own sorting rules, use `sort-method` or `sort-by`. If you need remote sorting from backend, set `sortable` to `custom`, and listen to the `sort-change` event on Table. In the event handler, you have access to the sorting column and sorting order so that you can fetch sorted table data from API. In this example we use another attribute named `formatter` to format the value of certain columns. It accepts a function which has two parameters: `row` and `column`. You can handle it according to your own needs.

 ### Expandable row
 
 When the row content is too long and you do not want to display the horizontal scroll bar, you can use the expandable row feature.
 :::demo Activate expandable row by adding type="expand" and slot. The template for el-table-column will be rendered as the contents of the expanded row, and you can access the same attributes as when you are using `slot` in custom column templates.

 ### Summary row
 
 For table of numbers, you can add an extra row at the table footer displaying each column's sum.
 :::demo You can add the summary row by setting `show-summary` to `true`. By default, for the summary row, the first column does not sum anything up but always displays 'Sum' (you can configure the displayed text using `sum-text`), while other columns sum every number in that column up and display them. You can of course define your own sum behaviour. To do so, pass a method to `summary-method`, which returns an array, and each element of the returned array will be displayed in the columns of the summary row. The second table of this example is a detailed demo.

 ### Ligne de somme
@@ -1462,36 +1370,17 @@ Lorsque le contenu d'une ligne est trop long et que vous ne souhaitez pas affich
 Pour les tableaux de nombres, vous pouvez ajouter une ligne en plus pour afficher la somme de chaque colonne.
 
 :::demo Mettez l'attribut `show-summary` à `true` dans `el-table`. Par défaut, la première colonne n'affiche que 'Sum' (vous pouvez configurer ce label avec `sum-text`), alors que les autres affichent la somme de chaque colonne. Vous pouvez choisir comment effectuer l'opération grâce à `summary-method`, qui doit retourner un tableau, cahque élément correspondant à la somme de chaque colonne. La deuxième table de cet exemple montre tout cela en pratique.

-| Attribut      | Description          | Type      | Valeurs acceptées       | Défaut  |
-|----------------|----------------------|-----------|-----------------------|----------|
-| data | Les données de la table. | array | — | — |
-| height | La hauteur de la table. Par défaut la hauteur est `auto`. Si sa valeur est un nombre, la hauteur est en px; si c'est un string, la valeur est assigné au style.height de l'élement. La hauteur est affectée par les styles externes. | string / number | — | — |
-| max-height | Table's max-height. The legal value is a number or the height in px. | string / number | — | — |
-| stripe | Si la table est rayée. | boolean | — | false |
-| border | Si la table à une bordure verticale. | boolean | — | false |
-| size | Taille de la table. | string | medium / small / mini | — |
-| fit | Si la largeur des colonnes s'adapte au conteneur. | boolean | — | true |

-| row-style | Fonction qui retourne un style pour chaque ligne. Peut aussi être un objet assignant un style à chaque ligne. | function({ row, rowIndex }) / object | — | — |
-| cell-class-name | Fonction qui retourne un nom de classe pour chaque cellule. Peut aussi être une simple chaîne de caractères assignant une classe à chaque cellule. | function({ row, column, rowIndex, columnIndex }) / string | — | — |

-| header-cell-style | Fonction qui retourne un style pour chaque cellule de header. Peut aussi être un objet assignant un style à chaque cellule de header. | function({ row, column, rowIndex, columnIndex }) / object | — | — |
-| row-key | Clé de chaque ligne, utilisée pour optimiser le rendu. Requise si `reserve-selection` est activé. Quand c'est un `String`, l'accès multi-niveaux est supporté, e.g. `user.info.id`, mais `user.info[0].id` n'est pas supporté. Dans ce dernier cas une `Function` devrait être utilisée. | function(row) / string | — | — |
-| empty-text | Texte à afficher quand il n'y a pas de données. Vous pouvez changer cette zone grâce à `#empty`. | string | — | No Data |

-| expand-row-keys | Détermine les lignes qui sont étendues, contient les clés des lignes correspondantes. Vous devriez configurer `row-key` avant celle-ci. | array | — | — |
-| default-sort | Détermine l'ordre de tri par défaut. La propriété `prop` détermine la colonne par défaut, `order` détermine l'ordre par défaut. | object | `order`: ascending / descending | Si `order` est absent, son défaut sera `ascending`. |
-| tooltip-effect | Propriété `effect` de Tooltip. | string | dark / light | dark |

 选择多行数据时使用 Checkbox。
 
 :::demo 实现多选非常简单: 手动添加一个 `el-table-column`，设 `type` 属性为 `selection` 即可；默认情况下若内容过多会折行显示，若需要单行显示可以使用 `show-overflow-tooltip` 属性，它接受一个 `Boolean`，为 `true` 时多余的内容会在 hover 时以 tooltip 的形式显示出来。

 ### 排序

 对表格进行排序，可快速查找或对比数据。
 
 :::demo 在列中设置 `sortable` 属性即可实现以该列为基准的排序，接受一个 `Boolean`，默认为 `false`。可以通过 Table 的 `default-sort` 属性设置默认的排序列和排序顺序。可以使用 `sort-method` 或者 `sort-by` 使用自定义的排序规则。如果需要后端排序，需将 `sortable` 设置为 `custom`，同时在 Table 上监听 `sort-change` 事件，在事件回调中可以获取当前排序的字段名和排序顺序，从而向接口请求排序后的表格数据。在本例中，我们还使用了 `formatter` 属性，它用于格式化指定列的值，接受一个 `Function`，会传入两个参数：`row` 和 `column`，可以根据自己的需求进行处理。

 ### 展开行
 
 当行内容过多并且不想显示横向滚动条时，可以使用 Table 展开行功能。
 :::demo 通过设置 `type="expand"` 和 `slot` 可以开启展开行功能，`el-table-column` 的模板会被渲染成为展开行的内容，展开行可访问的属性与使用自定义列模板时的 `slot` 相同。

 ### 表尾合计行
 
 若表格展示的是各类数字，可以在表尾显示各列的合计。
 :::demo 将 `show-summary` 设置为 `true` 就会在表格尾部展示合计行。默认情况下，对于合计行，第一列不进行数据求合操作，而是显示「合计」二字（可通过 `sum-text` 配置），其余列会将本列所有数值进行求合操作，并显示出来。当然，你也可以定义自己的合计逻辑。使用 `summary-method` 并传入一个方法，返回一个数组，这个数组中的各项就会显示在合计行的各列中，具体可以参考本例中的第二个表格。
