el-table中添加 row-class-name，绑定@row-click事件

<el-table:data="list":row-class-name="tableRowClassName"@row-click="handleRowClick"
>
</el-table>

给el-table中的每个row对象里添加index属性

tableRowClassName({ row, rowIndex }) {row.index = rowIndex;
},

点击

handleRowClick(row, column, event) {console.log(row,row.index)
}
