1. 英文改为中文

转为中文的方式：用 ElementPlus的日历组件如何改为中文

2. 修改样式

<script setup lang="ts">

3. 自定义头部

<el-calendar v-model="value" ref="calendar">
   <template #header="{ date }">
       <el-button-group>
           <el-button size="small" @click="selectDate('prev-year')">
               上一年
           </el-button>
           <el-button size="small" @click="selectDate('prev-month')">
               上个月
           </el-button>
       </el-button-group>
       <span>{{ date }}</span>
       <el-button-group>
           <el-button size="small" @click="selectDate('today')">今天</el-button>
           <el-button size="small" @click="selectDate('next-month')">
               下个月
           </el-button>
           <el-button size="small" @click="selectDate('next-year')">
               下一年
           </el-button>
       </el-button-group>
   </template>
<el-calendar/>



const value = ref(new Date());
const dateList = ref([])
const calendar = ref();
const selectDate = (val) => {
    dateList.value.length = 0
    calendar.value.selectDate(val);
};
function handleMonthChange(date) {
    dateList.value.push(date)
    // date 是切换后的日期，根据这个日期来计算开始日期和结束日期
    // const year = date.getFullYear();
    // const month = date.getMonth();
    // const startDate = new Date(year, month, 1); // 开始日期
    // const endDate = new Date(year, month + 1, 1); // 结束日期


    //根据开始日期和结束日期来查询数据，然后更新视图
    // ...
}

4. 增删改功能接入

    <div class="container my-container">
        <a-card :bordered="false" :style="{ width: '100%' }">
            <el-calendar v-model="value" ref="calendar">
