用vue写个系统后台用户管理界面嘛

当然可以！以下是一个示例代码，用 Vue 框架和 Element UI 组件库搭建一个用户管理后台界面：

<template>
  <div>
    <el-table :data="users">
      <el-table-column prop="id" label="ID"></el-table-column>
      <el-table-column prop="name" label="用户名"></el-table-column>
      <el-table-column prop="email" label="邮箱"></el-table-column>
      <el-table-column prop="status" label="状态" :formatter="statusFormatter"></el-table-column>
      <el-table-column label="操作">
        <template slot-scope="scope">
          <el-button type="primary" size="small" @click="editUser(scope.row)">编辑</el-button>
          <el-button type="danger" size="small" @click="deleteUser(scope.row)">删除</el-button>
        </template>
      </el-table-column>
    </el-table>
    <el-dialog :visible.sync="dialogVisible" title="编辑用户">
      <el-form :model="form">
        <el-form-item label="用户名" :label-width="formLabelWidth">
          <el-input v-model="form.name"></el-input>
        </el-form-item>
        <el-form-item label="邮箱" :label-width="formLabelWidth">
          <el-input v-model="form.email"></el-input>
        </el-form-item>
        <el-form-item label="状态" :label-width="formLabelWidth">
          <el-select v-model="form.status">
            <el-option label="正常" value="normal"></el-option>
            <el-option label="禁用" value="disabled"></el-option>
          </el-select>
        </el-form-item>
      </el-form>
      <div slot="footer" class="dialog-footer">
        <el-button @click="dialogVisible = false">取消</el-button>
        <el-button type="primary" @click="saveUser">保存</el-button>
      </div>
    </el-dialog>
  </div>
</template>

<script>
import axios from 'axios'

export default {
  data() {
    return {
      users: [],
      dialogVisible: false,
      formLabelWidth: '80px',
      form: {
        id: '',
        name: '',
        email: '',
        status: ''
      }
    }
  },
  created() {
    this.getUsers()
  },
  methods: {
    getUsers() {
      axios.get('/api/users').then(response => {
        this.users = response.data
      })
    },
    editUser(user) {
      this.form = Object.assign({}, user)
      this.dialogVisible = true
    },
    saveUser() {
      axios.put(`/api/users/${this.form.id}`, this.form).then(response => {
        this.getUsers()
        this.dialogVisible = false
      })
    },
    deleteUser(user) {
      if (confirm(`确定要删除用户 ${user.name} 吗？`)) {
        axios.delete(`/api/users/${user.id}`).then(response => {
          this.getUsers()
        })
      }
    },
    statusFormatter(status) {
      return status === 'normal' ? '正常' : '禁用'
    }
  }
}
</script>

这是一个非常基础的示例，仅包含了用户列表、编辑和删除功能。你可以根据自己的需求，添加更多功能和页面元素。同时，你也需要根据你的后端 API 接口进行相应的数据请求和处理。
