+### 自定义日期文案
+
+通过传入`formatter`函数来对日历上每一格的内容进行格式化
+
+```html
+<van-calendar
+  v-model="show"
+  type="range"
+  :formatter="formatter"
+/>
+```
+
+```js
+export default {
+  methods: {
+    formatter(day) {
+      const month = day.date.getMonth();
+      const date = day.date.getDate();
+
+      if (month === 4) {
+        if (date === 1) {
+          day.topInfo = '劳动节';
+        } else if (date === 4) {

+### 平铺展示
+
+将`poppable`设置为`false`，日历会直接展示在页面内，而不是以弹层的形式出现
