### 最主要就是用到属性的绑定 :class （动态绑定多个class） ###

:class="\[(k+1)%2==1?'trclock':'',curId==k?'trhover':'',selectedId==k?'trselected':''\]"

(k+1)%2==1?'trclock':'' 当前行是奇数行则使用 trclock样式；

curId==k?'trhover':'' 当curId==k时 trhover样式添加进当前TR，通过mouseenter mouseleave 两个函数来控制curId的值；

selectedId==k?'trselected':'' 当selectedId==k时 trselected 样式添加进当前TR，通过点击事件select(k)来设置selectedId的值；
