xlsx 用来处理要导出的数据一般常用的就是json_to_sheet() 和table_to_sheet() json_to_sheet用来处理后台返回的json数据格式 table_to_sheet用来处理页面中的table表格
xlsx-style 用来设置导出表格的样式 上下左右居中、颜色、字体大小、表格的边框…
下载 xlsx xlsx-style
npm install xlsx xlsx-style
引入
// 源码什么的都不需要改动
import XLSX from 'xlsx';
import XLSXStyle from 'xlsx-style';
在vue页面中调用
import { createWs, sheet2blob, openDownloadDialog } from "../../utils/exportExcel"
const titles = {
landNumber: '宗地号',
name: '姓名',
xiangName: '乡名称',
cunName: '村名称',
createTime: '档案上传日期',
qlrSignTime: '权利人签署日期',
typeList: '驳回原因'
}
const fields = ['landNumber', 'name', 'xiangName', 'cunName', 'createTime', 'qlrSignTime', 'typeList']
const ws = createWs(
this.excelData, // 后台返回的json数据
fields,
titles
)
openDownloadDialog(sheet2blob(ws), '权利人分析.xlsx');
配置表格的方法(创建的js文件)
export function createWs(data, fields, titles) {
const ws = XLSX.utils.json_to_sheet(data, {
header: fields,
});
/*const = merges: [
