Vue3导入表格功能

<el-table :data="datas" style="width: 100%" id="exportTableRef"></el-table>

// 导入依赖
import * as XLSX from "xlsx/xlsx.mjs";
 
// 导出方法
exportBtn() {
    let table_elt = document.getElementById("exportTableRef")
 
    // Extract Data (create a workbook object from the table)
    let workbook = XLSX.utils.table_to_book(table_elt);
 
    // Process Data (add a new row)
    let ws = workbook.Sheets["Sheet1"];
    XLSX.utils.sheet_add_aoa(ws, [], {
      origin: -1,
    });
 
    // Package and Release Data (`writeFile` tries to write and save an XLSB file)
    XLSX.writeFile(workbook, "导出.xlsx");
}
