        <el-col :span="12">
          <el-form-item>
            <el-button type="primary" @click="onSubmit">立即创建</el-button>
            <el-button>取消</el-button>
          </el-form-item>
        </el-col>
      </el-form>
    </el-row>
  </div>
</template>

<script>
export default {
  name: 'HelloWorld',
  data () {
    return {
      form: {
        name: '',
        region: '',
        date1: '',
        date2: '',
        delivery: false,
        type: [],
        resource: '',
        desc: ''
      }
    }
  },
  methods: {
    onSubmit () {
      console.log('submit!')
    }
  }
}
</script>

<style scoped>

</style>

如上图demo，我没理解复选框为什么不能左移，解决的办法是什么？有没有遇到的呢？

Answer 1

没用过element-ui，借鉴ant design提供个参考。
首先，row和col最好还是保持父子关系，<el-form><el-row>而不要<el-row><el-form>
其次，这种情况通常是<el-col>的高度差导致的，可以考虑使用多个<el-row>避免这个情况，或者先通过<el-row><el-col></el-col><el-col></el-col></ed-row>形成两列的布局，然后在每列中添加多个element就行了。

Answer 2

复现了下，他的布局是使用float+width实现的，而不是flex，其中有几个el-form-item的高度是28，有的是29，这是bug的原因，很奇怪，具体原因不清楚，你可以统一设置下高度
