row-key:【function】行数据的 Key,用来优化 Table 的渲染;在使用 reserve-selection 功能与显示树形数据时,该属性是必填的。类型为 String 时,支持多层访问:
user.info.id
,但不支持 user.info[0].id
,此种情况请使用 Function
。expand-row-keys:【Array 】 可以通过该属性设置 Table 目前的展开行,需要设置 row-key 属性才能使用,该属性为展开行的 keys 数组。
expand-change:【事件Table Events】当用户对某一行展开或者关闭的时候会触发该事件(展开行时,回调的第二个参数为 expandedRows;树形表格时第二参数为 expanded)
