fullcalander只渲染了一部分

[enginefuture]

您好，想请问一个问题，我把个人主页页面当到了对话框，打开对话框后，日历组件不能全部渲染出来。

<template>
  <el-dialog
    :model-value="dialogVisible"
    @close="close"
    :title="mode === 'add' ? '新增' : mode === 'edit' ? '编辑' : '查看'"
    width="90%"
    @open="handleDialogOpen"
    draggable
  >
    <el-tabs @update:modelValue="handleTabChange">
      <el-tab-pane label="个人中心">
        <div class="page-container">
          <div class="info" />
          <el-row :gutter="20">
            <el-col :span="7" :offset="1">
              <el-card class="box-card">

日历组件只渲染了一部分，拖动窗口后大小后，才会完全渲染完成。
