＜el-table＞ 表头的字数多于5时，表头单元格的字符串的行、列数按近似黄金分割比例 (√5 - 1)/2 排列

以下是基于Element UI的组件的实现方式：

1. 在中添加自定义的表头模板，并给表头模板绑定一个ref。

<el-table-column prop="name">
  <template slot="header">
    <div ref="tableHeader" class="custom-header">
      {{ $column.label }}
    div>
  template>
el-table-column>

1. 在 mounted 钩子中获取表头单元格的行、列数，并根据黄金分割比例进行排列。

mounted() {
  this.$nextTick(() => {
    const tableHeader = this.$refs.tableHeader;
    const headerWidth = tableHeader.offsetWidth;
    const headerHeight = tableHeader.offsetHeight;
 
    // 黄金分割比例
    const ratio = (Math.sqrt(5) - 1) / 2;
 
    // 计算行数和列数
    const rowCount = Math.ceil(1 / ratio);
    const colCount = Math.ceil(ratio);
 
    // 计算每个单元格的宽度和高度
    const cellWidth = headerWidth / colCount;
    const cellHeight = headerHeight / rowCount;
 
    // 将单元格位置设置为绝对定位
    tableHeader.style.position = 'relative';
 
    // 遍历每个单元格并设置它的位置
    let row = 0;
    let col = 0;
    Array.from(tableHeader.childNodes).forEach((cell) => {
      cell.style.position = 'absolute';
      cell.style.left = `${col * cellWidth}px`;
      cell.style.top = `${row * cellHeight}px`;
      col++;
      if (col === colCount) {
        col = 0;
        row++;
      }
    });
  });
}

完整的代码示例可以参考以下代码片段：

<template>
  <el-table :data="tableData">
    <el-table-column prop="name">
      <template slot="header">
        <div ref="tableHeader" class="custom-header">
          {{ $column.label }}
        div>
      template>
    el-table-column>
    <el-table-column prop="age" label="Age">el-table-column>
    <el-table-column prop="gender" label="Gender">el-table-column>
  el-table>

<script>

  data() {
    return {
      tableData: [
        { name: 'John Doe', age: 30, gender: 'Male' },
        { name: 'Jane Doe', age: 25, gender: 'Female' },
        { name: 'Bob Smith', age: 40, gender: 'Male' },
      ],
    };
  },
  mounted() {
    this.$nextTick(() => {
      const tableHeader = this.$refs.tableHeader;
      const headerWidth = tableHeader.offsetWidth;
      const headerHeight = tableHeader.offsetHeight;
 
      // 黄金分割比例
      const ratio = (Math.sqrt(5) - 1) / 2;
 
      // 计算行数和列数
      const rowCount = Math.ceil(1 / ratio);
      const colCount = Math.ceil(ratio);
 
      // 计算每个单元格的宽度和高度
      const cellWidth = headerWidth / colCount;
      const cellHeight = headerHeight / rowCount;
 
      // 将单元格位置设置为绝对定位
      tableHeader.style.position = 'relative';
 
      // 遍历每个单元格并设置它的位置
      let row = 0;
      let col = 0;
      Array.from(tableHeader.childNodes).forEach((cell) => {
        cell.style.position = 'absolute';
        cell.style.left = `${col * cellWidth}px`;
        cell.style.top = `${row * cellHeight}px`;
        col++;
        if (col === colCount) {
          col = 0;
          row++;
        }
      });
    });
  },
};
