element-ui绑定delete按钮不触发点击事件

源代码:

<template slot-scope="scope">
    <el-button type="warning" @click="edit(scope.row)">编辑</el-button>
    <el-button type="danger" @click="delete(scope.row)">删除</el-button>
</template>

更改后:

<template slot-scope="scope">
    <el-button type="warning" @click="edit(scope.row)">编辑</el-button>
    <el-button type="danger" @click="showDelete(scope.row)">删除</el-button>
</template>
