vue element table expand 扩展行点击行展示且保证只展示一行

背景:因为element里面的扩展行支持多行展示扩展行,但接到了需求,只能展示一行,如:第一行扩展,点击第二行的时候,第一行收起,第二行展开。同时改成点击行展示扩展内容

:data="eventTableData"
style="width: 100%"
@cell-click="clickTable"
ref="refTable"
@selection-change="handleSelectionChange"
@expand-change="expandSelect"
>

data:{

eventTableData:[],

expands:[],

}

methods:{

clickTable:function(row, column, cell, event){//展开事件日志列表
if(cell.cellIndex!=3 && cell.cellIndex!=10){
this.refs.refTable.toggleRowExpansion(row); } this.getnoTicketReason(1) { that.expands = [] if (row) { that.expands.push(row); } this.">refs.refTable.toggleRowExpansion(expandedRows[0]);
} else {
that.expands = [];
}
},

}
