::: title 设置第几步状态

这里设置`status` 会覆盖掉`current-status`

        <lay-step-item title="Fourth" content="Fourth step"></lay-step-item>
    </lay-step>
<lay-button size="xs" @click="previous">上一步</lay-button>
<lay-button size="xs" @click="nexts">下一步</lay-button>
</div>
</template>

import { ref } from 'vue';

export default {
  setup() {
    const loading = ref(true);
    const active = ref(-1);
    const nexts = () => {
      if (active.value++ >=3) active.value = 0
    };
    const previous = () => {
