可以使用第三方库"xlsx"来导出xlsx文件,并通过设置表头和样式来自定义导出的文件。具体实现步骤如下:
1. 安装"xlsx"库:
```javascript
npm install xlsx --save
```
2. 导入"xlsx"库和数据:
```javascript
import XLSX from 'xlsx';
const data = [
{ name: "张三", age: 18, sex: "男" },
{ name: "李四", age: 20, sex: "女" },
{ name: "王五", age: 22, sex: "男" }
];
```
3. 定义表头和样式:
```javascript
const headers = ["姓名", "年龄", "性别"];
const styles = {
header: {
fill: {
fgColor:{rgb:"EDEDED"}
},
font: {
color: { rgb: "000000" },
bold: true
}
},
cell: {
font: { sz: 14 }
}
}
```
4. 定义导出文件的格式和文件名:
```javascript
const fileType = 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet;charset=UTF-8';
const fileExtension = '.xlsx';
const fileName = '用户信息表';
```
5. 将数据转换为表格:
```javascript
const worksheet = XLSX.utils.json_to_sheet(data);
```
6. 设置表头和样式:
```javascript
worksheet["A1"].v = headers[0];
worksheet["B1"].v = headers[1];
worksheet["C1"].v = headers[2];
worksheet["A1"].s = styles.header;
worksheet["B1"].s = styles.header;
worksheet["C1"].s = styles.header;
let range = XLSX.utils.decode_range(worksheet["!ref"]);
for(let i = 1; i <= range.e.r; i++) {
let ref = XLSX.utils.encode_col(0) + i;
worksheet[ref].s = styles.cell;
ref = XLSX.utils.encode_col(1) + i;
worksheet[ref].s = styles.cell;
ref = XLSX.utils.encode_col(2) + i;
worksheet[ref].s = styles.cell;
}
```
7. 将表格增加到工作簿中:
```javascript
const workbook = XLSX.utils.book_new();
XLSX.utils.book_append_sheet(workbook, worksheet, "Sheet1");
```
8. 导出xlsx文件:
```javascript
const file = XLSX.write(workbook, { bookType: 'xlsx', type: 'buffer' });
let blob = new Blob([file], {type: fileType});
saveAs(blob, fileName + fileExtension);
```
