row-key:【function】行數據的 Key,用來優化 Table 的渲染;在使用 reserve-selection 功能與顯示樹形數據時,該屬性是必填的。類型為 String 時,支持多層訪問:
user.info.id,但不支持
user.info[0].id,此種情況請使用
Function。
expand-row-keys:【Array 】 可以通過該屬性設置 Table 目前的展開行,需要設置 row-key 屬性才能使用,該屬性為展開行的 keys 數組。
expand-change:【事件Table Events】
當用戶對某一行展開或者關閉的時候會觸發該事件(展開行時,回調的第二個參數為 expandedRows;樹形表格時第二參數為 expanded)
