以下是基于Element UI的<el-table>组件的实现方式:
- 在<el-table-column>中添加自定义的表头模板,并给表头模板绑定一个ref。
html
<el-table-column prop="name">
<template slot="header">
<div ref="tableHeader" class="custom-header">
{{ $column.label }}
</div>
</template>
</el-table-column>
- 在 mounted 钩子中获取表头单元格的行、列数,并根据黄金分割比例进行排列。
js
mounted() {
this.$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:
html
<template>
<el-table :data="tableData">
<el-table-column prop="name">
<template slot="header">
<div ref="tableHeader" class="custom-header">
{{ $column.label }}
</div>
</template>
</el-table-column>
<el-table-column prop="age" label="Age"></el-table-column>
<el-table-column prop="gender" label="Gender"></el-table-column>
</el-table>
</template>
<script>
export default {
data() {
return {
tableData: [
{ name: 'John Doe', age: 30, gender: 'Male' },
{ name: 'Jane Doe', age: 25, gender: 'Female' },
{ name: 'Bob Smith', age: 40, gender: 'Male' },
],
};
},
mounted() {
this.$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++;
}
});
});
},
};
</script>
<style scoped>
.custom-header {
display: flex;
align-items: center;
justify-content: center;
font-weight: bold;
font-size: 18px;
}
</style>
