Vue 3 中使用 Element Plus 的 `el-table` 组件实现自适应高度

npm install element-plus --save
# 或者
yarn add element-plus
   

<template>
  <div ref="tableContainer" class="table-container">
    <el-table
      :data="tableData"
      :height="tableHeight"
      style="width: 100%"
    >
      <el-table-column prop="date" label="日期" width="180"></el-table-column>
      <el-table-column prop="name" label="姓名" width="180"></el-table-column>
      <el-table-column prop="address" label="地址"></el-table-column>
    </el-table>
  </div>
</template>
<script>
import { ref, onMounted, onUnmounted } from 'vue';
import { ElTable, ElTableColumn } from 'element-plus';
export default {
  components: {
    ElTable,
    ElTableColumn,

      // 更多数据...
    ]);
    const tableContainer = ref(null);
    const tableHeight = ref(0);
    const updateTableHeight = () => {
      if (tableContainer.value) {
        // 计算表格的高度
        const containerRect = tableContainer.value.getBoundingClientRect();
        const containerHeight = containerRect.height;
        tableHeight.value = containerHeight - 20; // 减去一些边距或标题栏的高度
      }
    };
    // 监听窗口大小变化
    const handleResize = () => {
      updateTableHeight();
    };
    onMounted(() => {
      updateTableHeight(); // 初始化时计算一次高度
      window.addEventListener('resize', handleResize);
    });
    onUnmounted(() => {
      window.removeEventListener('resize', handleResize);
    });
    return {

      tableHeight,
      tableContainer,
    };

<style scoped>
.table-container {
  height: 100vh; /* 你可以根据需要调整这个值 */
  overflow: auto;
}
</style>
