要创建多级表头,您可以使用以下步骤:
1. 首先,您需要定义表头的结构。您可以使用包含多个级别的数组来表示多级表头。例如:
```
const headers = [
[
{ header: "First Name", key: "firstName", width: 10 },
{ header: "Last Name", key: "lastName", width: 10 }
],
[
{ header: "Address", key: "address", width: 20 },
{ header: "City", key: "city", width: 10 },
{ header: "State", key: "state", width: 10 },
{ header: "Zip Code", key: "zipCode", width: 10 }
]
];
```
在这个示例中,我们定义了一个包含两个级别的表头。第一级包含“First Name”和“Last Name”两个列,第二级包含“Address”、“City”、“State”和“Zip Code”四个列。
2. 接下来,您可以使用`json_to_sheet`函数创建工作表。在第二个参数中,将表头结构传递给`header`属性。例如:
```
const sheet = XLSX.utils.json_to_sheet(data, { header: headers });
```
这将创建一个多级表头的工作表。
完整代码示例:
```
const data = [
{ firstName: "John", lastName: "Doe", address: "123 Main St", city: "Anytown", state: "CA", zipCode: "12345" },
{ firstName: "Jane", lastName: "Smith", address: "456 Oak Ave", city: "Otherville", state: "TX", zipCode: "67890" }
];
const headers = [
[
{ header: "First Name", key: "firstName", width: 10 },
{ header: "Last Name", key: "lastName", width: 10 }
],
[
{ header: "Address", key: "address", width: 20 },
{ header: "City", key: "city", width: 10 },
{ header: "State", key: "state", width: 10 },
{ header: "Zip Code", key: "zipCode", width: 10 }
]
];
const sheet = XLSX.utils.json_to_sheet(data, { header: headers });
```
