element ui table 导出excel表格

1.安装相关依赖 xlsx file-saver

npm intall --save xlsx
npm intall --save file-saver

2.在组件头里边引入插件

import FileSaver from "file-saver";
import XLSX from "xlsx";

3.定义导出Excel表格事件

exportExcel() {
      let fix = document.querySelector(".el-table__fixed");
      let wb;
      if (fix) {
        //判断要导出的节点中是否有fixed的表格，如果有，转换excel时先将该dom移除，然后append回去 可以避免行重复
        wb = XLSX.utils.table_to_book(
          document.querySelector("#table").removeChild(fix)
        );
        document.querySelector("#table").appendChild(fix);
      } else {
        wb = XLSX.utils.table_to_book(document.querySelector("#table"));
      }
      let wbout = XLSX.write(wb, {
        bookType: "xlsx",
        bookSST: true,
        type: "array",
      });
      try {
        //文件名可以自定义
        FileSaver.saveAs(
          new Blob([wbout], { type: "application/octet-stream" }),
          "仪表数据.xlsx"
        );
      } catch (e) {
        if (typeof console !== "undefined") console.log(e, wbout);
      }
      return wbout;
    },

4.template中 table加上id

5. 按钮绑定导出excel事件

<el-button
      type="primary"
      @click="exportExcel"
      >导出表格</el-button
    >
